MAVLink Control Vehicle Speed

Dear All,

I would like to slow down or speed up vehicle through MAVLink protocol.

msg.msgid = MAVLINK_CMD_DO_CHANGE_SPEED // #178

// output_buf shows “FE 08 91 01 01 B2 01 00 01 00”
How to send output_buf message to control vehicle speed?

Many thanks. Please advice.

Best Regards,

I can only suggest to use MAVSDK to avoid having to deal with low level MAVLink.
