Hello,
I am running Chirpstack and I have encountered an issue that I’m hoping to get some help with. I searched the forums, but didn’t find any issues substantially similar to mine.
I can provide any logs, configuration, or additional information required upon request.
When I boot up my LoRa device, my sensor will not successfully communicate correctly for a period of time before the sensor internally resets and requests a new Join. This is repeatable and happens every time.
Here is the sequence if the sensor and LoRa device are turned on at the same time:
-JoinRequest
-JoinAccept
-ConfirmedUp
-UnconfirmedDown
-ConfirmedUp
-ConfirmedUp
-ConfirmedUp
-ConfirmedUp
-ConfirmedUp
-…etc until the sensor does an internal reset
-JoinRequest
-JoinAccept
-ConfirmedUp
-UnconfirmedDown
-ConfirmedUp
-UnconfirmedDown
-…and so on, it works as expected now
If the LoRa device is restarted but the sensor is not, it looks like this:
-ConfirmedUp
-ConfirmedUp
-ConfirmedUp
-ConfirmedUp
-ConfirmedUp
-…etc until the sensor does an internal reset
-JoinRequest
-JoinAccept
-ConfirmedUp
-UnconfirmedDown
-ConfirmedUp
-UnconfirmedDown
-…and so on, it works as expected now
I have looked at the transmissions as best I can, but I don’t understand what is going on or why the message are being “ignored” by Chirpstack until the device does a Join the second time.
There is a lot of data, so I will link it:
