Bluetooth corrections with all-in-one micro pcb

Here is a quick write-up on using bluetooth corrections with an All In One micro pcb.

My requirements:

  1. Use a bluetooth xbee to send corrections to a single micro f9p from Lefebure android app.
  2. Lefebure NTRIP app needs gga from the bluetooth xbee.

Steps to achieve this;

  1. Send NMEA out on UART2

  2. Change UART2 Baudrate to 38400 to allow communication with xbee

  1. Enable GGA messages on UART2 (DON’T FORGET TO SAVE THIS CONFIGURATION!)

  1. Now we have a problem, because there is no way to send the GGA message from UART2 to the xbee. I’m sure there is a better solution, but here is what works for me.

Solder a wire from one of these highlighted pins…

to this pin.

This is how I did it.

RTK!!!
