SIYI HM30 Ground Unit Unable to Connect to a particular Cube via Mission Planner

Cube Autopilot
1

Hello,

I’m encountering an issue where my Ground Unit is unable to connect to the Cube using Mission Planner. The setup seems correct, and I’ve checked the following:

  • The Cube and Ground Unit are set to the same baud rate.
  • The correct COM port is selected in Mission Planner.
  • The telemetry connection is secure and powered correctly.

Despite these checks, Mission Planner fails to establish a connection. The Companion Computer can connect to the Cube via MAVProxy without issues, but the Ground Unit cannot connect through Mission Planner.

Has anyone faced a similar problem or can suggest any troubleshooting steps to resolve this?

This is happening on only 1 cube in the lot, others it is working fine with SIYI

Thanks for your assistance!
