i work with WGM110 with BGlib API, 1.0.1 sdk version. It communicates with an extern MCU.
there are some specifications about the time the module needs to elaborate a command?
if i want to start a server?
if i want to connect to a server?
How much is the time between the command response and the conclusive event?
There are no such specs, other than you need to wait for each command response before sending the next command. The time between command and associated event(s) (if any) depends on the command, there are no strict timings for those.
there are a max time limit for the command response?
if i send a command, is it possible that i wait indefinitely before i receive the response?
There is no spec for this as I mentioned above but you shouldn't be waiting indefinitely for a response. This is something you can obtain empirically, but if you want a guess I would say 100ms should be more than enough.
