Making custom parameters in QGC

#1

I’ve been trying for a while to add new parameters that I can edit in QGroundControl but nothing seems to work. Anyone done this before? how did you do it and does it show up fully in QGroundControl?

Hello!
Parameter protocol is explained here: https://mavlink.io/en/services/parameter.html
Your MAV should receive message with id PARAM_REQUEST_LIST from GCS right after connect.
Then, MAV should send its parameters one by one to GCS using mavlink predefined structure named “mavlink_param_value_t”.

For example:

mavlink_param_value_t param;
param.param_count = [number of MAV parameters]
param.param_index = [id of MAV parameter]
param.param_type = [MAV_PARAM_TYPE::select_type_here]
param.param_value = value_of_parameter

Then encode this structure to mavlink message and send to GCS.
