Yesterday we decided to migrate to v3 version, chosen one of our applications and used windows CLI tool to generate and export devices JSON. All devices were activated by ABP.
After re-creating the devices in v3, we not only were not able to make them work but it also stopped working in v2 (other, untouched applications are still working). No live data for the devices both in v2 and v3, I have triple checked all IDs and keys. We have changed application name in v3 to more accurate, but I believe it’s not important?
Finally after checking through other threads tried to change ABP to OTAA for one device but still not lucky. Also, we didn’t migrate all gateways as I’ve read that they point to v2 ones anyway.
We’re not really experienced in TTN, in v2 it was very easy for us to setup the gateways/devices but we struggle here. Any help would be appreciated.
