Not able to send command

[Gocrackit]

I am not able to change the mode. Can anyone please help me out how to change the mode.

My code

var changeMode=SetMode(customMode: 216, targetSystem: 1, baseMode: 88); var frm = MavlinkFrame.v1(sequence, systemId, componentId, paramRequestList); socket.send(frm.serialize(), d.address, d.port);
