I have a Pixhawk Lite (mavID: 1) and an AlceOSD (mavID: 200) connected in my Plane (running Plane 3.6 f/w)
On connecting MP to this setup over telemetry radio, I almost immediately get connected to the Pixhawk, I can see the underlaying HUD data being updated, but then MP is still trying to gain a connection with the OSD which it tries and eventually times out. Instead of just allowing the Pixhawk connection to remain usable, it then disconnects all devices, including the Pixhawk and I am left disconnected. So because of one problem device, I can not connect and use MP with Pixhawk.
Eventually after about 10 retries, I manage to get connected to both devices successfully and MP is then usable finally. My gripe here is that all it takes is one problem device to render MP unusable. Can the connection method please be reconsidered to improve connectivity in situations such as the above?
