Persist OTAA Keys / ABP Counter

[dbrgn]

Is there a way to persist the keys that were negotiated during OTAA? Or alternatively, can I somehow extract them to persist (and then restore) them myself?

Similarly, can I somehow extract and restore the packet counter in ABP mode?

If I'm not mistaken, this is possible with the RN2483 modules.

Oh, I missed those. Thanks.

This is not possible yet and already discussed in:

https://forum.pycom.io/topic/1407/how-to-save-and-restore-lorawan-context-using-.

Some modules like the RN2483 do support it, some others like the RM186 don't. IMHO LoRaWan doesn't offer a clear, best-practice, strategy for doing this.

With the LoPy you could of course add the functionally to the firmware since the source code is available .
