Part 1 – AT Commands for All Universal IP Devices  
Chapter 1 – General AT Commands for All Universal IP Devices  
#LEGACYMODE – Legacy Mode Enable/Disable  
About Legacy Mode:  
Note: This command is for all devices except the SocketEthernet IP (MT100SEM-IP)  
Legacy mode allows for smoother transition to TCP/IP based connectivity from standard analog  
interface connections.  
When #LEGACYMODE=1, the stack will be in pseudo legacy mode where the commands &S,  
&D, &C, A, D, S0, E, V operate independently of the stack. The commands will be saved to a  
different NVRAM location and will not affect the IP stack once legacy mode has been exited.  
Once in legacy mode, the user can configure the #TCP values and issue an ATD command to  
make a connection to the remote host. If necessary, the user can also issue  
ATDxxxxxxxxxxxxppppp where x is the decimal address and ppppp is the remote port. The stack  
will perform the physical connection and present the user with the proper messages:  
NO CARRIER  
NO ANSWER  
CONNECT  
OK  
ERROR  
Description: If legacy mode is enabled, the AT interface tries to behave like a legacy analog modem. ATD and  
ATA will function on the TCP stack instead of the physical connection. Responses will behave like  
that of an analog modem.  
Syntax:  
Set Value: AT#LEGACYMODE=1  
View Values: AT#LEGACYMODE?  
Values:  
Default:  
0 Disable legacy mode  
1 Enable legacy mode  
0
#RESET – Reset Main Processor or Internal Modem  
Description: This command will force a reset on the Stack and internal radio or just the internal radio.  
Syntax:  
Values:  
AT#RESET =<value>  
0 Reset the Stack and internal modem  
1 Reset the internal modem only.  
Note: This value is not valid for the SocketEthernet IP (MT100SEM-IP) and the  
SocketWireless Wi-Fi (MT810SWM-IP)  
AT#RESET=0  
Example:  
Note:  
After issuing AT#RESET, it can take up to 45 seconds before the MT810SWM-IP is ready to  
accept AT Commands. When configuring the MT810SWM-IP using security mode WPA or  
WPA2, the bootup time will take longer.  
#SHIELDCHAR – Configure the Shielding Character for DLEMODE  
Description: This parameter defines the shield character for the clients that use shielding (also known as DLE  
shielding with regards to UIP).  
Note: This command is for all devices except the SocketWireless Wi-Fi (MT810SWM-IP)  
Syntax:  
AT#SHIELDCHAR=[<parameter1>]  
AT#SHIELDCHAR?  
Values:  
0-255 (an integer value between 0 and 255)  
Responses:  
\r\n#SHIELDCHAR: VALUE\r\n

cases, the TCP/IP stack software will provide the SMTP password (associated to the SMTP user  
name) for the email sending process.  
If this parameter is an empty string, the authentication mode is inactive.  
If both this parameter and the SMTPUN parameter are not empty, the authentication mode is  
active.  
Syntax:  
Values:  
AT#SMTPPW="<value>"  
AT#SMTPPW? Read or display the current setting (or AT#VSMTP, AT#VALL).  
Alphanumeric ASCII text string up to 64 characters. No default.  
#SMTPSERV – Set SMTP Server Address  
Description: To send email messages the TCP/IP stack software must know the address of the SMTP server  
that is to be used. In most cases, the local ISP maintains the SMTP server.  
Syntax:  
AT#SMTPSERV="<value>"  
AT#SMTPSERV? Read or display the current setting (or AT#VSMTP, AT#VALL).  
Values:  
32-bit number in dotted-decimal notation (i.e., xxx.xxx.xxx.xxx) or  
Alphanumeric ASCII text string up to 120 characters if DNS is available. No default.  
#SMTPUN – Set SMTP User Name  
Description: To send email messages, some SMTP servers use an authentication process. In these cases,  
the TCP/IP stack software will provide the SMTP user name (associated with a SMTP password)  
for the email sending process.  
If this parameter is an empty string, the authentication mode is inactive. If both this parameter and  
the SMTPPW parameter are not empty, the authentication mode is active.

#SENDMAILi – Send Mail without Interactive Mode  
Important Note: MT5692SMI-IP supports only SENDMAIL1 options.  
Description: This command sends one of the 3 pre-defined email combinations. Once an IP link is established,  
the attached host can direct the TCP/IP stack to send an email message at any time (except  
when the TCP/IP stack software is already in a process using TCP resources).  
The header of this email is built using the REC1/2/3, CCREC1/2/3 and SUBJ1/2/3 parameters  
while the body is filled in the BODY1/2/3 parameter.  
This command is similar to a “send email” operation issued by a standard messaging client on a  
PC.  
Syntax:  
AT#SENDMAILi  
Example:  
Note: In #SENDMAILi, the i is to be replaced with #SENDMAIL1, #SENDMAIL2, or  
#SENDMAIL3.

Notes: An error has occurred during the communication with the remote  
SMTP server. It may also happen during the data transfer (after the  
OK message).  
This error can be due to one of the following reasons:  
-
The DNS servers are not able to resolve the SMTP server  
address  
-
-
-
The SMTP server is temporarily out of service  
The authentication (SMTPUN, SMTPPW) is not valid  
Email address specified in REC1 or CCREC1 is not valid

#PUTMAIL – Send Mail to Recipient with Interactive Mode  
Description: This command allows the attached host to send an email message containing body text passed  
to the TCP/IP stack over the serial port. Once an IP link is established, the attached host can  
send an email message at any time (except when the TCP/IP stack software is already in a  
process using TCP resources).  
The header of this email is built using the REC1, CCREC1 and SUBJ1 parameters.  
This command is similar to a “send email” operation issued by a standard messaging client on a  
PC.  
Syntax:  
AT#PUTMAIL  
IMPORTANT NOTE:  
You must issue the <CR><LF> bytes (binary value: 0D 0A) as the first data bytes if a header is  
NOT being constructed in order to finish the internal headers correctly. This mechanism is in  
place to allow for the addition of custom headers such as MIME data.  
Command  
Possible Responses  
AT#PUTMAIL  
Ok_Info_WaitingForData  
Note: You have to configure only  
receiver address1, copy address1, and  
subject1 before or during the session,  
but content (body) of the email is typed  
when the TCP/IP session is  
established. Content is not echoed.  
Notes: An SMTP session has been successfully opened  
with the remote SMTP server.  
Once the TCP/IP stack has displayed this message,  
all the data received on the serial port is sent within  
the email body.  
The (CR)(LF)(.)(CR)(LF) sequence sent by the  
attached host indicates the TCP/IP stack the end of  
the email body.  
<CR><LF>  
Note: See Important Note above.

#FTPGET – Download Files from FTP Server  
Description: This command, sent by the attached host, directs the TCP/IP stack to connect to the specified  
FTP server and to retrieve the specified file from this server. Once the operation is completed, the  
TCP/IP stack closes the FTP connection.  
Once an IP link is established, the attached host can retrieve a file from an FTP server at any  
time (except when the TCP/IP stack software is already in a process using TCP resources).  
This command is similar to a GET operation (with an automatic connect/disconnect) issued by a  
standard FTP client on a PC. The TCP/IP stack handles the global FTP process by itself.  
Note: The TCP/IP stack will signal the attached host of the end of the file that is being  
downloaded with a single <ETX> character. The <ETX> characters that are part of the file data  
will be shielded as <DLE><ETX>. The <DLE> characters that are part of the file data will be  
shielded as <DLE><DLE>. The attached host will need to remove the shielding <DLE>  
characters.

#FTPPUT – Upload Files to FTP Server  
Description: This command sent by the attached host directs the TCP/IP stack to connect to the specified FTP  
server and to upload the data received on the serial port to the specified file on this server. Once  
the operation is completed, the TCP/IP stack closes the FTP connection.  
Once an IP link is established, the attached host can send a file to a FTP server at any time  
(except when the TCP/IP stack software is already in a process using TCP resources).  
This command is similar to a PUT operation (with an automatic connect/disconnect) issued by a  
standard FTP client on a PC. The TCP/IP stack handles the global FTP put process by itself.  
Note: The TCP/IP stack will interpret only an <ETX> character as the end of the file to be  
transferred if it’s not preceded by a <DLE> character. As a consequence, the attached host must  
send <ETX> characters preceded by <DLE> characters, and it must also code <DLE> characters  
as <DLE><DLE>.

Chapter 4 – FTP AT Commands  
#FTPGETPATH – Set Path to Get a File from FTP Server  
Description: In order for the TCP/IP stack software to get a file from the FTP server, the TCP/IP stack software  
must know the path of the relevant file. For example: ftp.companyx.com/wireless/WPST or, if you  
at in the root ftp.companyx.com, you can then simply type /  
Syntax:  
AT#FTPGETPATH="<value>"  
AT#FTPGETPATH? Read or display the current setting (or AT#VFTP, AT#VALL).  
Values:  
Alpha-numeric ASCII text string up to 120 characters.  
Note: Depending on the FTP server, the value can be used for getting a file from the root  
directory of the FTP server. No default.  
#FTPPUTPATH – Set Path to Send Files to FTP Server  
Description: In order for the TCP/IP stack software to send a file to the FTP server, the TCP/IP stack software  
must know the path of the relevant file. For example: ftp.companyx.com/wireless/WPST or, if you  
at in the root ftp.companyx.com, you can then simply type /  
Syntax:  
AT#FTPPUTPATH="<value>"  
AT#FTPPUTPATH? Read or display the current setting (or AT#VFTP, AT#VALL).  
Values:  
Alpha-numeric ASCII text string up to 120 characters.  
Note: Depending on the FTP server, the value can be used for getting a file from the root  
directory of the FTP server. No default.  
#FTPAPPEND – Append Data to Server  
Description: This command sent by the attached host directs the TCP/IP stack to connect to the specified FTP  
server and to append the data received on the serial port to the specified file on this server. Once  
the operation is completed, the TCP/IP stack closes the FTP connection.  
Once an IP link is established, the attached host can send a file to a FTP server at any time  
(except when the TCP/IP stack software is already in a process using TCP resources).  
This command is similar to a PUT operation (with an automatic connect/disconnect) issued by a  
standard FTP client on a PC. The TCP/IP stack handles the global FTP put process by itself.  
Note:  
Certain conditions must be met in order to use this command. First, the FTP server must support  
this command as some servers do and some servers don't. Also, the client performing the  
APPEND operation must read/write to the FTP server as well.  
Syntax:  
AT#FTPAPPEND  
#FTPNETWORKTIMER – FTP Client Network Transmit Safety Timeout Value  
Description: This parameter determines the inactivity time in seconds of the TCP TX buffer.  
Note: This command is for all devices except the SocketWireless Wi-Fi (MT810SWM-IP)

#PERSISTENTSOCKET - Persistent Socket  
Description: If enabled and the physical connection is present, a socket will be created automatically.  
Note: This command is for all devices except the SocketEthernet IP (MT100SEM-IP).  
Syntax:  
AT#PERSISTENTSOCKET=<Persistentsocket value>,<Result Codes>  
AT#PERSISTENTSOCKET? Read or display the current setting (or AT#VALL).  
Values:  
0 – Persistent socket is disabled  
1 – The TCP originate is started (#OTCP=1)  
2 – The TCP listener is started (#LTCPSTART=1)  
3 – The UDP originate is started (#OUDP=1)  
4 – The UDP listener is started (#LUDPSTART=1)  
5 – The TCP originate is started (#OTCP=2)  
6 – The TCP originate is started (#LTCPSTART=2)  
Result Codes: 0 All result codes will be suppressed during socket connection/disconnection  
1 All result codes will be displayed during socket connection/disconnection  
Defaults:  
Example:  
0,1  
AT#PERSISTENTSOCKET=1,0  
#DLEMODE – Set DLE Mode  
Description: When using socket TCP, the attached host has the choice whether or not to code the ETX  
character.  
Syntax:  
AT#DLEMODE=id,<DEL Mode value>  
AT#DLEMODE=id Read or display the current setting (or AT#VTCP=id, AT#VALL).  
id:  
Enter a Profile Setting: 1 or 2 {1,2}  
Values:  
Set the value that the Profile will use:  
0
1
When DLEMODE is set to 0, no specific process is needed on [ETX] characters.  
It means that it is not possible for a host to request an end of connection or to receive a clear  
indication of the end of a connection from the TCP/IP stack.  
When DLEMODE is set to 1, the [ETX] character means a request or an indication of end of  
connection.  
As a consequence, [ETX] characters that belong to the payload data must be sent by the  
host on the serial port preceded by a DLE character. Similarly, ETX characters received by  
the TCP/IP stack from the Internet are sent to the host through the serial port preceded by a  
DLE character.  
Default:  
1

#TCPPORT – Set TCP Port for Remote Peer  
Description: To exchange data over TCP, the TCP/IP stack software must know the port of the remote peer  
used for the TCP session.  
Syntax:  
AT#TCPPORT=id,<TCP Port number for remote peer value>  
AT#TCPPORT=id Read or display the current setting (or AT#VTCP=id, AT#VALL).  
id:  
Values:  
Enter a Profile Setting: 1 or 2 {1,2}  
Set the value that the Profile will use:  
From 1 to 5 digits (each digit between 0 and 9 inclusive). Note that numbers above 65,535 are  
illegal as the port identification fields are 16 bits long in the TCP header.  
Default:  
1
#TCPSERV – Set Address of Remote TCP Server  
Description: To exchange data over TCP, the TCP/IP stack software must know the address of the remote  
TCP server (or host) that is to be used.

#LTCPSTART – Open Listening Mode  
Description: This command, sent by the attached host, directs the TCP/IP stack to open a listening TCP  
connection on the specified TCP port.  
Once an IP link is established, the attached host can open a listening TCP socket at any time  
(except when the TCP/IP stack software is already in a process using TCP resources).  
The TCP connection will be active upon reception of a TCP connection request sent by a remote  
allowed TCP peer (TCPSERV) on the appropriate TCP port (TCPPORT).  
Once opened, this TCP connection may be closed by the remote TCP peer or by the attached  
host by sending an ETX character on the serial port (depending on the DLEMODE parameter).  
Notes:  
The LTCP command can be aborted before an incoming TCP request has been received by  
issuing an <ETX> character on the serial port.  
If the DLEMODE parameter is set to 1, the TCP/IP stack will interpret an <ETX> character only as  
a close request if a <DLE> character does not precede it. As a consequence, the attached host  
must send <ETX> characters preceded by <DLE> characters, and it must also code <DLE>  
characters in <DLE><DLE>. Similarly, each <ETX> character present in the payload data of the  
TCP frame will be coded by the TCP/IP stack on the serial port as <DLE><ETX>. Each <DLE>  
character will be coded as <DLE><DLE>. The attached host must then decode the TCP socket  
flow to remove these escape characters.  
If the DLEMODE parameter is set to 0, the TCP/IP stack will never close the TCP connection  
(unless an error occurs).  
Syntax:  
AT#LTCPSTART=id  
id:  
Values:  
Enter a Profile Setting: 1 or 2 {1,2}

#OUTPORT – UDP/TCP Local Port Number  
Description: Controls the local port that the UDP/TCP connection is bound to.  
Syntax:  
Values:  
AT#OUTPORT=<Port Number value>  
AT#OUTPORT? Read or display the current setting (or AT#VALL ).  
Set the port number local connection will use:  
From 1 to 5 numeric digits (0 to 9).  
Note: Numbers above 65,535 are illegal since port identification fields are 16-bits long in the  
IDP header.  
Default:  
37500  
#OTCP – Open a TCP Connection  
Description: This command sent by the attached host directs the TCP/IP stack to open a TCP connection to  
the specified TCP server. Once an IP link is established, the attached host can open a TCP  
connection at any time (except when the TCP/IP stack software is already in a process using  
TCP resources).  
This TCP connection may be closed by the remote TCP server or by the attached host via  
sending an ETX character on the serial port (depending on the DLEMODE parameter).  
DLEMODE Value Notes:  
Depending on the DLEMODE value, the attached host may close this TCP connection by sending  
an ETX character.  
• If the DLEMODE parameter is set to 1, the TCP/IP stack will only interpret an <ETX> character  
as a close request if it’s not preceded by a <DLE> character. As a consequence, the attached  
host must send <ETX> characters preceded by <DLE> characters, and it must also code  
<DLE> characters in <DLE><DLE>. Similarly, each <ETX> character present in the payload  
data of the TCP frame will be coded by the TCP/IP stack on the serial port as <DLE><ETX>.  
Each <DLE> character will be coded as <DLE><DLE>. The attached host must then decode  
the TCP socket flow to remove these escape characters.  
• If DLEMODE is set to 0, the host cannot close the TCP connection (unless an error occurs).  
If the remote TCP server closes the connection, the TCP/IP stack sends an ETX character on the  
serial port.

id:  
Values:  
AT#OTCP=id

#UDPDLEMODE – Set DLE Mode  
Description: The attached host has the choice whether or not to code the ETX character.  
Note: This command is for all devices except the SocketWireless Wi-Fi (MT810SWM-IP).  
Notes:  
If UDPDLEMODE is disabled, the user MUST use the RS232 DTR signal to perform a socket  
disconnect or disconnect the network connection  
Details:  
If UDPDLEMODE is enabled, these rules must be followed: The user must shield all transmitted  
ETX ([x03]) and DLE (x10) characters by preceding these characters with a DLE (x10).  
The UIP stack will shield all UDP received ETX ([x03]) and DLE (x10) characters by preceding  
these characters with a DLE (x10), the user must un-shield by removing the DLE (x10) shield  
character.  
An example payload to transmit from user to UIP stack:  
(x01 x02 x03 x04 x01 x10) must be sent to the UIP stack as: (x01 x02 x10 x03 x04 x01 x10  
x10). Notice the x10 before the [x03] and before the x10.  
An example received payload by the UIP over UDP:  
(x01 x02 x03 x04 x01 x10) is received by the UIP stack, the user will receive: (x01 x02 x10  
x03 x04 x01 x10 x10). Notice the x10 before the [x03] and before the x10.  
In summary: Encoding - 0x03 == 0x10 0x03  
Encoding - 0x10 == 0x10 0x10

#ANSWERMODE – Set Answering Mode  
Description: The TCP/IP stack can handle incoming calls. This parameter defines how the TCP/IP stack will  
behave when receiving an incoming call.  
Syntax:  
Values:  
AT#ANSWERMODE=<value>  
AT#ANSWERMODE? Read or display the current setting (or AT#VPHY, AT#VALL).  
0 - Ignore. Ignores the incoming call. In this case, it is the responsibility of the host to accept/not  
accept the incoming call by issuing the AT#ACCEPT command.  
1 - Automatic Answer. The TCP/IP stack goes off hook and accepts the incoming call. As  
described below, the calling number must match the one specified in the CALLSCREENNUM  
parameter. (The RINGCOUNT parameter must be > 0).  
2 - Static Callback. The TCP/IP stack ignores the incoming call and then automatically dials  
(DIALN1 or DIALN2 determined by the DIALSELECT parameter) by issuing an  
AT#CONNECTIONSTART command. The calling number must match the one specified in  
the CALLSCREENNUM parameter. The RINGCOUNT parameter must be > 0.  
3 - Dynamic Callback. The TCP/IP stack ignores the incoming call and then automatically dials  
the calling number by issuing an AT#CONNECTIONSTART command. For this feature, the  
Caller ID service is mandatory. As described below, the calling number must match the one  
specified in the CALLSCREENNUM parameter.  
4 - Automatic Connection Using SMS. The TCP/IP stack matches the message from an  
incoming SMS message to the #SMSPHRASE parameter. If a match occurs,  
#CONNECTIONSTART is issued. (The RINGCOUNT parameter must be 0).  
0
Default:  
Note: If #ANSWERMODE is set to a value other than 0, the user must enable caller ID. To  
enable caller ID, use the command AT+CLIP=1.  
Note: A wake-up SMS message will NOT work if the device is busy.  
#SMSPHRASE – Set Incoming SMS Phrase  
Description: When receiving an incoming SMS and #ANSWERMODE=4, the SMS message allows the  
TCP/IP stack to identify a specific message from the sender. This information is helpful in  
preventing unauthorized SMS to trigger actions on the TCP/IP stack.  
Notes: A setting of 0 (zero) disables all remote SMS messages.  
This command is for all devices except the SocketWireless Wi-Fi (MT810SWM-IP)  
Syntax:  
AT#SMSPHRASE="<parameter1>"  
AT#SMSPHRASE? Read or display the current setting.

#CALLBACKTIMER – Set Automatic Call-Back Wait  
Description: This parameter defines the number of seconds the TCP/IP stack will wait before an automatic  
call-back operation occurs after receiving an incoming call. It applies only when the  
ANSWERMODE parameter is set to an automatic call-back mode (value>1). This timer starts at  
the end of the ringing signal.  
Syntax:  
AT#CALLBACKTIMER=<value>  
AT#CALLBACKTIMER? Read or display the current setting (or AT#VPHY, AT#VALL).  
Values:  
Default:  
Integer between 2 and 255 inclusive. This timer is set in seconds.

#CALLSCREENNUM – Set Caller ID Service  
Description: When receiving an incoming call, the caller identification (Caller ID) service allows the TCP/IP  
stack to identify the phone number of the remote caller. This information is helpful in preventing  
unauthorized callers to trigger actions on the TCP/IP stack.  
This parameter allows the user to filter the incoming calls when the ANSWERMODE parameter is  
set to an automatic mode (value>0). This filtering doesn’t apply when the ANSWERMODE  
parameter is set to 0. In this case, it is the host’s responsibility to accept or reject the incoming  
call. If an incoming phone number is not authorized, the TCP/IP stack will ignore it.  
Syntax:  
Values:  
AT#CALLSCREENNUM=<value>  
AT#CALLSCREENNUM? Read or display the current setting (or AT#VPHY, AT#VALL).  
0 - Zero. Remote caller not authorized.

About GPIO  
If the specific hardware allows GPIO (check availability with AT#GPIO=1), then you may specify certain external  
events from the GPIOs to trigger specific stack functions; i.e., email, upload files, download files. In order for this  
to work, you must configure the specific function first. For instance, if SENDMAIL1 will be called, then all  
settings pertaining to SENDMAIL1 must be configured before the #GPIO command is configured.  
Note:  
MultiModem iCell: The MultiModem iCell allows for the following GPIO IDs and GPIO function combinations:  
GPIO 1 - 2: GPIO function 0 may be selected  
GPIO 3 - 4: GPIO functions 0, 1, 2 and 3 may be selected  
GPIO 5:  
GPIO function 3 may be selected  
SocketModem iCell: The SocketModem iCell allows for the following GPIO IDs and GPIO function combinations:  
GPIO 1 - 2: GPIO function 0 may be selected  
GPIO 3 - 4: GPIO functions 0, 1, 2 and 3 may be selected  
GPIO 5:  
GPIO 5 is non-functional  
#GPIO – Enable/Disable and Configure External GPIO Driven Events

Chapter 16 – AT Commands for GPS-Enabled Devices  
GPS Message Syntax  
GPS message syntax that is sent from the UIP device to the backend server:  
<GPSPREFIX><GPSURAIS><NMEA_MESSAGE><CR><LF>  
Where  
<GPSPREFIX> is the unique prefix. Length is 0 to 4 characters (Character format or requirements  
usually provided by backend service)  
<GPSURAIS> is the unique remote asset identification string. Length is 0 to 20 characters (This  
string may be provided by the backend service)  
<NMEA_MESSAGE> is a standard NMEA sentence received from the internal GPS receiver  
<CR><LF> is a Carriage Return and a Line feed  
The message that will be transmitted can be viewed with the #GPSGETMESSAGE command. The  
difference from the viewed message and the transmitted message will be the NMEA message parameters  
due to timestamp changes and or location changes.  
The <GPSPREFIX><GPSURAIS><NMEA_MESSAGE><CR><LF> is a popular format used by numerous  
services. Along with the format, the following rules are followed:  
Typical transmission protocol is UDP (format provided by backend service) due to low overhead, however  
TCP is available  
Multiple GPS message can and will be transmitted granted the specific message type is enabled  
(GPSGPVTG, GPSGPRMC, etc)  
Typical minimum message type needed by the backend services is usually the GPRMC or GPGGA and  
GPVTG messages (Requirement provided by the backend server)  
Do not use the $ character in either the <GPSPREFIX> or <GPSURAIS> sections  
Typical transmission intervals to the backend service are 5sec and greater (Requirement provided by  
backend server)  
GPS Message Examples  
The following examples use a <GPSPREFIX> configured to && and a <GPSURAIS> configured with  
ID1111

Application Note – GPS NMEA Messages  
Introduction  
The NMEA (National Marine Electronics Association) 0183 Standard is a standard protocol for  
interfacing navigational devices; e.g., GPS and DGPS receivers over a serial interface. The  
complete document of this standard may be obtained from NMEA at http://www.nmea.org. We  
wish to thank SkyTraq Technology, Inc. for providing the following summary of NMEA Messages.  
NMEA Protocol Overview  
Message Format  
The structure of an NMEA message is shown below.  
Checksum Range  
Start of  
Sequence  
$ or !  
Address Field Data Field(s)  
<Address>  
Checksum  
Field  
End of  
Sequence  
[,<data field>] [,<data field>] *<checksum> <CR><LF>  
Start of Sequence  
All sentences begin with the sentence start delimiter character “$” or “!”.  
Address Field  
The address field is used to define the sentence. Characters with digits and upper case letters  
are permitted to be in the address field. Note that the address field is required. It cannot be a null  
field. This field is subdivided into 2 fields.  
<XX>  
<XXX>  
Talker Identifier  
Sentence Formatter  
Talker Identifier is always GP for a GPS receiver. The sentence formatter defines the format and  
the type of data.  
Data Field(s)  
Data fields are delimited by a “,” and contain valid characters specified in NMEA 0183 standard. It  
can consist of fields of variable lengths.  
Checksum  
The checksum field is the 8-bit exclusive OR (no start or stop bits) of all characters in the  
sentence. Checksum consists of 2 characters and is represented as a hex number.  
End of Sequence  
All sentences always end with sentence termination delimiter character “$” or “!”.
