Hello, to request a single parameter you need the param_id or param_index.
Where do you get this information from? Must you do a
PARAM_REQUEST_LIST first to get a list of all the parameters then parse out the one you want?
Thanks!
Well, yes, if you don’t know the textual name of the parameter to stick
into PARAM_REQUEST_READ.param_id, then you’re going to have to get the
list and let the user work out which one they want 
Note that the name is the only stable identifier for a parameter; the
numeric ID used for mavlink transfer is ephemeral.
