lora_pkt_fwd

[Máté Eckl]

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,
Máté

$ mts-io-sysfs show lora/product-id
MTAC-LORA-868
$ mts-io-sysfs show lora/hw-version
MTAC-LORA-1.0

This card is a USB card and must use the /opt/lora/basic_pkt_fwd or gps_pkt_fwd binaries.

v3.x packet forwarder with V2 protocol is not available for USB cards.
V1 protocol is used in basic/gps pkt_fwds

I do not now and ever have had basic_pkt_fwd on my install. I thought it to be a mistake in the manual.

Could you tell me the name of the package from which I can install this executable?

Thank you very much, it seems to be working fine.
