Failed to start the concentrator - Lorank8 Issue with Packet Forwarder v4.0.1"

Hello everyone,

I am encountering an issue with my Lorank8 gateway after updating the Packet Forwarder to version 4.0.1 (Semtech Packet Forwarder) and using the software from Ideetron’s repository.

When I run lora_pkt_fwd, the program fails to start, giving me the following error:

root@lorank8:/home/debian/lorank8v1# ./start
Starting the standard Semtech packet forwarder.
*** Beacon Packet Forwarder for Lora Gateway ***
Version: 4.0.1
*** Lora concentrator HAL library version info ***
Version: 5.0.1;

In the system logs (/var/log/syslog), I see this message:

Nov 27 09:41:35 lorank8 systemd[1]: lorank.service: Unit entered failed state.

I would appreciate any guidance or troubleshooting steps to resolve the issue.

Thank you in advance!

Yes, I am still experiencing the same issue. It hasn’t been resolved, so this topic is still needed.
