kimson305@gmail.comMy system : b-l072z-lrwan board
Sending cycle : 20s
Connected device number : 22
question :
Initially, all devices are connected and data is received.
I can see all device’s packet node-red & LoRaWAN – Packets
After a few days, you will not be able to receive data after the device is disconnected.
If you do not restart the device, the symptoms are the same.
Note that the device does not stop. I2C or LED operates normally.
What could be the cause of this?
frequency occupancy?
TxTime is too short?
