Maybe its the fact we are not setting the below in the config line and only setting bit rate
Do you know the below settings for mission planner maybe we could match them on ser2net or ser2net take interface defaults if not set
This is what we use:
ser2net -c udp,14550:raw:600:/dev/ttyAMA0:57600 remaddr=ipv4,udp,192.168.0.7,4550
Maybe it should be:
ser2net -c udp,14550:raw:600:/dev/ttyAMA0:57600 8DATABITS NONE 1STOPBIT remaddr=ipv4,udp,192.168.0.7,4550
But unsure what the settings are for Pixhawk so the serial on the pi3 matches
