To get around this issue, end-device rejoins once every 10 days.
The worst case scenario is that the G/w dies right after a sensor rejoin, and comes back up after 10 days. In this case the sensor data is missed until the next sensor re-join (10 days worst case).
Sensors session on the end-device side is alive and the
F_Cnt
is increasing. The G/W also sees the sensor traffic. TTN cannot see sensors.Todo:
