SIK Radio Configuration via Cube Orange USB Passthrough

Hello,

I’m working with a Cube Orange running ArduCopter 4.3.8 and Mission Planner 1.3.80. My RFD900 radio is buried deep within the UAV, making it very inconvenient to access its serial port directly for configuration.

Sometimes I forget the radio’s frequency settings, which prevents me from connecting to it or the Cube via RF. I’m trying to use the USB connection to the Cube (via Mission Planner) to configure the radio using serial passthrough, but it doesn’t seem to work.

Does ArduPilot support configuring RFD900 radios through the Cube’s USB passthrough, or is there a workaround to access the radio settings without directly connecting to its serial port?

Thanks in advance for any insights or suggestions!

Passthrough support has probably been improved in 4.4.x, 4.5.x and 4.6.x
