How to change NwkSKey?

[mhruska]

Hello,

I need to change NWKSKEY as my end device as hard coded one. I found an option to do it under end deivces - General Settings - Network Layer however when I try to update it I get this error message:

Submit failed
Invalid value of field session.keys.nwk_s_enc_key.key

Thanks

That means you have to add the end device as ABP, not OTAA. The ABP dialog allows entering your own session keys.
