Notes
- GPS, GLONASS, SBAS, QZSS are enabled by default
- Blue PPS LED blinking (1Hz) means 3D is fixed
- Update rate of 1Hz & baudrate of 9600 are default
- Baud 9600 - 115200 are supported by INAV/BF/Ardupilot
- Update rate of 5Hz with INAV UBLOX Protocol
- Update rate of 10Hz with INAV UBLOX7 Protocol
- Compass alignment (arrow forward):
- INAV/BF: CW 270° Flip
- Ardupilot/Mission Planner: Rotation None
- BF doesn’t support GPS position hold and RTH
- GPS Rescue mode is supported by BF3.5 or last
- No need compass for fixed wings with INAV firmware
- The scratches on ceramic antenna are the result of tuning the antenna by UBLOX.
