hi there
I used QGC and with mavlink connected with my AP.
when connect to my AP, “Parameters” button in “vehicle setup” is on and I did not understand, how to respond and handle msg in “MAVLINK_MSG_ID_PARAM_SET” !!!
I tried with “mavlink_msg_param_value_pack” to respond it (with same index), but QGC did not accept.
HOW TO SOLVE THAT???
OK
I solve it but not complete, i checked with if condition and delete it and my job become OK.
my variable in QGC and AP changed but QGC after some times notify me to no respond param_set
I confused
