LoRa® - How can I tell if I am still joined to the network?
After I have joined a network over OTAA, how can I subsequently tell if I am still joined to this or any network?
In order to get the status of the module you can try to use the mac get status command. This command returns the current status of the module. The value returned is a 32-bit mask represented in hexadecimal form. The significance of the bit mask is described in the "RN2483 LoRa Technology Module Command Reference User's Guide" which can be downloaded from the RN2483 product page; go to Documents > User Guides.
Bit 0 represents the join status (0 - network not joined, 1 - network joined ).
