I was wondering are we able to receive rockblock messages from rpi or odroid, so if i wanted to send a command to rockblock to return to home, would i able to retrieve that message from the actual rockblock or would i need an internet connection on the rpi to receive that kind of message ?
Ardupilot supports the Rockblock directly, no need for RPi or Odroid: RockBLOCK Satellite Modem — Plane documentation
