I am working on an end device.
Most of the time the join process completes successfully - though I see an alarming number of times where it doesnt. I am hosting a gateway myself while developing.
I am using the LR1110 development board connected to a Nordic development kit.
Firmware version 1.0.7
The issue I am trying to wrap my head around is that after a successful join I see unsolicited upling data messages.
This has started after I implemented sending data earlier today. See the below picture for an example.
I could successfully see the data I transmitted earlier. I then stopped sending data and only joined the device. But the unsolicited messages kept showing up.
The message come in some 20 seconds after joining and sometimes more messages will show up with 10 seconds intervals consisting of just 2 bytes. On those 2-byte messages no port is listed.
The content of the larger package is very similar from time to time, only a few bytes change. One byte ( the 4B in the picture ) seem to be an increasing counter.
The 2-byte messages change content every time.
I can add that I have successfully received data from TTN.
However receiving can only happen a short while after joining as no events seem to be happening a short while after joining. It seems it could be in conjunction with some of those messages received in TTN…
Any tips and hints are highly appreciated.
