RN2483 end-device does not work

Hi there,

Some days ago I was testing some RN2483-based nodes and everything was working fine: end-devices transmitted messages and everything was shown in both consoles (application and gateway). However, although I did not even change the sketch or the hardware, I couldn’t see the traffic in the consoles anymore.

I’ve been trying to find out what could have happened, I can’t even see the join request of the end-device. I have tried registering a new device in the application (but appears as never seen) and replacing the LoRaWAN module, but still doesn’t work. I copy here the log file from the gateway:

I’m using an Arduino board with the RN2483 (LoRaWAN_08_join_otaa_send_unconfirmed), and the gateway is a Raspberry Pi 2B with the iC880A concentrator.

I printed the output of the Arduino sketch and it seems that there’s an error when the module attempts to set the EUI (LoRaWAN.setDeviceEUI(DEVICE_EUI))

Did something similar happen to anyone else? I appreciate any kind of help :grin:

did you find it ?

Hi @BoRRoZ,

I didn’t find it yet, is there an additional way to check that the gateway is working properly?

I changed the location of the gateway some weeks ago, but I used the network with the new location and I found no problem until some days ago. In any case, I’ll notify any advance.

Thank you for your interest :blush:

Hi Celia,

I’m sure you checked and double checked … just some ideas

  • can you reach the gateway with another node
  • start problems gateway (reset a few times)
  • powersupply gateway
  • did you try resetting the rn2483 to factory default
  • resetting the frame counter in console
  • obvious… battery, measure voltage on RN2483 when switched on
  • creating a new application with the ‘old’ node
  • creating a new node with the old application

Hi @BoRRoZ ,

I’ve checked these options, but I haven’t tried resetting several times the gateway or testing the power supply… I’ll test that and as soon as I find the problem I’ll post it :grin:

Regards,
Celia

Hi, I finally found the problem!

My gateway is deployed outdoors, so I though that the antenna could be in bad state due to bad weather conditions. However, everything seemed to be working fine.

I took the antenna and carried it indoors to analyse it in more detail and I found out an strange noise coming from the concentrator. It was the Vcc cable (from the Raspberry Pi to the concentrator) that wasn’t in good state :weary:

I have replaced it and soldered all unions in order to avoid future problems. Now it’s outdoors and everything working fine :grin:

I hope it helps other people with similar issues, thanks for your interest!!

Regards,
Celia
