I am measuring temperatures in my beehives.
Setup: cubecell-AB01, EU868, ABP, ADR=off, UNCONFIRMED uplinks, measurement every 15 minutes, deepsleep in between. My own Things Indoor gateway handles all traffic.
This worked great under TTN V2 for > 1year with hardly any uplinks lost.
Migrated my gateway to TTN V3, everything still worked fine.
Then I reprogrammed my cubecells to make the uplinks to V3 rather than V2.
After initial trouble (had to edit the RegioEU868.h file to get the correct RX timings) it seemed to work.
But:
- all my devices stop after exactly 84 uplinks, after reboot I have noticed that the LIPO batteries are partially drained, minus 0.3 Volt or so.
- sometimes each uplink causes a downlink.
- sometimes the cycle changes from 15 minutes to 10-15 seconds.
Any suggestions what I can do to resolve these issues?
