I had a situation where my lora gateway was offline for ~2 months and was brought back online.
I noticed the devices that were active on that gateway did not come back online (these are Elsys ERS motion sensors).
From viewing the uplinks coming from the back-online gateway I noticed that the devaddr of a device doing ConfirmedDataUp is the same as one in the device_activation table on chirpstack_ns postgres server. This leads me to think that the device is not configured to try to rejoin on not receiving downlinks.
- How do devices lose the Activation on the chirpstack application server? Is it based on time?
- Can I reinstate the existing activation and get the data flowing as expected?
- What else should I try?
