Cts/rts m+

I have a M+ that I am hooking up to pixhawk cube orange and was wondering if it is crucial to have cts/rts connected. I have only gps1 left as a serial port. How crucial is it to have flow when sending ERB to the cube?

Hi Matthew,

To output data from Reach M+ only TX, RX and GND pins are required.

I had the tx/rx backwards works like a charm now!
