lora_pkt_fwd

I am trying to configure a basic packet forwarder for my LoraWAN but nor the start script nor the manual way reaches to make it work.

With the init script it always seemed to start properly, but in the end there was no running packet forwarder process running, so I started trying to start it manually.
With the deamon I followed this tutorial and produced the steps necessarry for version <3.2 (mine is 3.12.27). I note that some of the steps were incorrect.

The output was the following:

root@mtcdt:/opt/lora# /etc/init.d/lora-packet-forwarder start
Found lora card MTAC-LORA-868
Starting lora-packet-forwarder: OK

The pid file is present, but the process is not running.

I started to debug this by running the program manually.

I’ve already gone through a lot of forum topics and issues, but they were mostly related to GPS or cellular modules which I don’t have.

The lora-network-server seemed to work properly before I started to reconfigure it.

My hardware configuration is the following:
- Multitech MultiConnect Conduit (MTCDTIP-220L-868-OP)
- 553/686 Lora module
- Ethernet module

Thanks in advanced,
