Network and application session keys the same among all my ABP devices

I have them the same on all my devices because it made it faster to program.

And what about the DevAddr?

(Typically the DevAddr is not unique for all existing devices, but that needs a unique NwkSKey indeed.)

And just to be sure: you’re not using the Semtech demo keys, right? (Both keys being 2B7E151628AED2A6ABF7158809CF4F3C for that.)
