I’m developing a custom Ground Control Station (GCS) for my UAV project, and I’m trying to get full telemetry link quality data directly from my telemetry radios. My telemetry radio supports the RADIO_STATUS (ID 109) MAVLink message, which reports fields like RSSI, remote RSSI, noise levels, TX buffer, and packet error counts. However, in my custom GCS I cannot see RADIO_STATUS by default. Behavior I’m seeing: If I first connect to the drone with Skydroid GCS, I can see RADIO_STATUS messages appearing in Skydroid. If I then close Skydroid GCS and connect my custom GCS, I still receive RADIO_STATUS normally. But if I reboot the drone and connect only my custom GCS (without using Skydroid first), I no longer receive RADIO_STATUS. It seems Skydroid GCS is doing something during the initial connection that causes the radio to start injecting RADIO_STATUS messages into the MAVLink stream. My GCS is not doing that yet.
Question: Has anyone else faced this? What handshake or initial packet do I need to send to trigger RADIO_STATUS injection right after connection, without having to use Skydroid first? Thanks in advance!
