SE878Kx-Ax Family EVK User Guide Communication Interface
Communication Interface
The modules offer several ways of communication to and from the host processor. For
simplicity in this document, the interface described in the examples is in UART mode.
Please refer to MT-GNSS Families Software User Guide for a full description of
messages and commands from/to the modules.
7.1 Commands
A command is a defined Data Packet sent from a host processor to the GNSS-Baseband
Controller. The regular structure of the command is:
message-ID,<PktType,data1,…,dataN>*<checksum><CR><LF>
Parameters, if present, are delimited by “,” characters as per the NMEA protocol. All commands
are proprietary and therefore all command-ID’s begin with the “$PMTK” character sequence.
7.2 Messages
Messages sent from the module to the host processor and have the basic structure illustrated
below:
message-ID,<PktType,data1,…,dataN>*<checksum><CR><LF>
Individual data fields are delimited by “,” characters. The checksum is provided for purposes
of bit error detection by the host if desired.
The modules output certain standard messages as defined in the NMEA-0183 protocol
standard. The message-ID for standard messages begins with an NMEA message ID: “$GP”
indicating GPS, “$GL” indicating GLONASS and “$GN” indicating global navigation.
The modules also output proprietary messages. As with commands, proprietary message-IDs
begin with “$PMTK.” Note that some proprietary messages are responses to input commands.
1VV0301480 Rev. 0 Page 23 of 27 2018-06-20
SE878Kx-Ax Family EVK User Guide Communication Interface
7.3 NMEA-0183 Messages Description
The table below summarizes the periodic output messages:
Message ID Description
$GPRMC Recommended minimum specific GNSS data
$GPGGA GNSS fix data. (Position, Navigation, and Time data
$GPVTG Course and speed over ground.
$GNGSA GNSS Active Satellites and Dilution of Precision (DOP)
$--GSV
GNSS satellites in view.
“GP” talker ID reports GPS
“GL” talker ID reports GLONASS satellites
“BD” talker ID reports BEIDOU satellites.
Table 7-1 Output Messages
All messages are output once per second. Multiple GSA and GSV messages may be reported
in each second.
