I’m trying to use a Reach M+ as part of a configuration for a drone, and am having issues with trying to get the whole system to work. We’re using a Pixhawk 2.1 Cube, and the Reach is powered separately. The serial ports and stop bits have all been checked, and I’m trying to use the Reach and the NMEA output from Mission Planner to push out GPS data . However, the Pixhawk isn’t recognizing that it has a GPS unit connected to it. I was wondering if anyone had previous experiences with this kind of issue or has any suggestions on how to make it work. Thanks.
