Hi!  
I try to set home position using mavlink command MAV\_CMD\_DO\_SET\_HOME  
Command accepted and executed, but home position doesn’t changed. MAVLINK\_STATUS\_TEXT displays old home position. What i’m doing wrong?  
mavlink\_message\_t msg;  
mavlink\_command\_long\_t cmd;  
cmd.command = (uint16\_t)MAV\_CMD\_DO\_SET\_HOME;  
cmd.param1 = 1.0f;  
cmd.param2 = 0.0f;  
cmd.param3 = 0.0f;  
cmd.param4 = 0.0f;  
cmd.param5 = lat;  
cmd.param6 = lon;  
cmd.param7 = alt;  
cmd.target\_system = ProtocolIDs::mavlinkVehicleID;  
cmd.target\_component = ProtocolIDs::mavlinkCompID;  
mavlink\_msg\_command\_long\_encode(ProtocolIDs::mavlinkSysID, ProtocolIDs::mavlinkCompID, &msg, &cmd);

PX4 Firmware: 1.5.5

Not sure where you’re sending it from, but cmd.target\_component might be wrong. Try 0 or 1 there.

Problem solved. cmd.target\_component = 1, cmd.target\_system = 1. Thanks!

One more question: what is the altitude of this command? Absolute (AMSL) or relative (AGL)? There is no information on this in the documentation.

Hi! I several years do not develop UAVs and unfortunately I can’t help with these issues.
