RAK 7205 5205 setup and TTN v3

Issue: Have both RAK5205 and RAK7205 devices and am trying to simply trying to get them to connect to a gateway. However, with both I follow the QSG (Quick Start Guide | RAKwireless Documentation Center) but with both devices I’m getting an “ERROR 82” from the serial terminal. Tried a number of different configs, but I feel like I’m missing a step. Doesn’t seem to even try to connect to a gateway.

Any help would be appreciated,
Thanks!

Welcome to RAK forum @mofresh :slight_smile:

Please try to input a value on APPEUI and not all 0.

An all 00’s AppEUI is valid, and recommended by TTNv3. I see this as a bug on the RAKwireless firmware side.
