Device not working as a class C device

[fainlaip]

Dear Gotthardp,

I am trying to establish my own LoRaWAN network and for that purpose I have decided to go with Your open source newtork server.
I am using STM32 devboards and Beckhoff PLC as a local host. I have successfully deployed and configured the network server and as the application server I am using Node-Red.

I have two issues regarding Your network server:

-in the STM32Cube IDE I have configured the end node as a class C device, but it is still operating as a class A device.
-the cycle for transmiting data is set to 30 seconds and at the beginning the device is indeed working properly, i.e. transmiting data every 30 seconds, but then, after maybe 10 or more cycles, it starts transmiting data every after 2-3 minutes.

After trying to debug these problems for some time, I decided to try and go with another network server (The things network) and there, with the same configuration, everythings seems to works fine. I am able to send downlinks whenever I desire to and the end node is transmiting uplinks after every 30 seconds for as long as it is active.

Looking forward to Your reply.

Best regards,

Filip
