Device_session_ttl undocumented? Where to put this setting to avoid ABP loosing there keys?

[IoTThinks]

I recommend to upgrade to latest ChirpStack v4.7.
Then the device session will not be expired any more.

Else you may try this with Chirpstack v4.5

Stop devices being deactivated after a time

Hi Is there a way to stop the LoRa App Server from deactivating devices. Our devices are not always on and we use ABP. So when we come to use them, half the time they dont work because they have been deactivated. We then have to go back through and reactivate them all. Thanks Chris
