4.2.2.34 "Turn On GPS Pass-through" command
This command will turn on the GPS engine and will output the NMEA messages from the GPS engine over the Bluetooth GATT
connection. The NMEA messages conform to NMEA-0183 rev. 3.0. The following NMEA messages are output at a one second
update rate:
GPRMC
•
GNRMC
•
GPGGA
•
GNGGA
•
GPGSA
•
GNGSA
•
GPGSV
•
GPGLL

GNGLL

Note: Depending on GPS engine configuration and status of the fix, all message types shown here may or may not
be present. For example, the ST100 board is shipped with its GPS engine configured to obtain location using both
GPS and GLONASS constellations. This results in several messages types (for example, GNGGA and GNGSA) to have
an "N" as the second character, indicating that the data within those messages was calculated from "aNy" satellite
constellation. Calculation from GPS only would result in a "P" in that position (for "gPs").
