While messing around with my MTK i found a weird initialization string in the AP_GPS_MTK_Common.h for waas.
It is currently:
#define WAAS_ON "$PSRF151,1*3F\r\n"
this string doesn't seem to be a valid command judging from the documentation.
Is it a 3Drobotics special?
Wouldn't this be correct?
#define WAAS_ON "$PMTK301,2*2E\r\n"
