Hello everyone,

I am trying to send customized data to my onboard computer from ground station. To avoid radio communication between ground station and onboard computer, I wish to send data to APM first and APM can re-send this data to the onboard computer by using USB cable.

Can anyone give me some suggestion to do that? Does it work if I send  the message FILE_TRANSFER_PROTOCOL (#110) of MAVLINK from ground station and let on-board computer to receive this message from APM?

I appreciate your help.
