TTN best practice states to store device address once OTAA join is successful. How do you retrieve the TTN device address using the Sodaq_RN2483 library?
It is not in the library at this moment. Keep in mind when you save the DevAddr, AppSKey and NwkSkey also save the FcntUp. When you re-connect with a lower counter, the frame counter checks inside TTN will block all your packages.
If you have suggestion to the library you can help us to make it better on GitHub!
