Sorry to reopen this thread but I tried adding an extra GPS module but wasn’t able to make it work. Hereis how I am trying to do it
I am using a GPS module based with the Ublox Neo-m8n chip and I am connecting it via the UART port
My etc/default/arducopter is as follow:
ARDUPILOT_OPTS="-A udp:192.168.1.29:14550 -E /dev/ttyAMA0"
I am not using radio telemetry so I removed the -C option.
I’ve set the mission parameters GPS_TYPE2, GPS_AUTO_SWITCH and SERIAL4 as instructed.
Any ideas what may be going wrong?
