Detailed Description

Summary of supported sentences (note: order changed): GLL - Lat, long, time, status RMC - Lat, long, time, status, speed, true heading, date, magnetic variation GGA - Lat, long, time, status (enhanced), #sats, horizontal precision, altitude, geoidal seperation, differentialGPS age, differentialGPS referenceID VTG - true heading, magnetic heading, speed knots, speed km/hr GSA - Satelite IDs GSV - Satelite SNR in dB data.

Todo:

(SRLM): this needs unit testing. I also haven't tested the inlining of the function.

Member Function Documentation

bool MTK3339::GetStatus ( void  )

inline

bool MTK3339::Start ( int  rxPin, int  txPin, int  ppsPin = -1  )

inline

Send configuration packets:

220 PMTK_SET_NMEA_UPDATERATE 100 (milliseconds, 10Hz) 251 PMTK_SET_NMEA_BAUDRATE 115200 (baud) 341 PMTK_API_SET_NMEA_OUTPUT GLL 0 (disabled) RMC 1 (10 Hz) VTG 0 (disabled) GGA 1 (10 Hz) GSA 5 (2 Hz) GSV 5 (2 Hz)

Requires that the previous baud be either 9600 (factory default) or 115200. Other baud rates are not supported, and will result in GetStatus() == false.
