Hi,

I am having trouble starting the packet forwarder using the web interface.
the status is always no matter how many times i restart or save and restart. Can someone help me out with this issue?

Hi,

You could try accessing the Conduit via SSH and try the following instructions:

1) To see why the packet forwarder is not getting started, look at output of forwarder when run from the command line:

# /etc/init.d/lora-network-server stop
# cd /var/run/lora/1/
# ./lora_pkt_fwd

See troubleshooting guide in Downloads on this page.

2) Try to manually reload the FPGA firmware. If this is not functioning as shown below, then there is a hardware issue:

# mts-io-sysfs store lora/creset 0
# mts-io-sysfs show lora/cdone
0 <<-- Expected output # mts-io-sysfs store lora/creset 1 # mts-io-sysfs show lora/cdone 1 <<-- Expected output

I used sudo and was able to start the concentrator manually.

sudo ./lora_pkt_fwd

I have installed LoRa gateway bridge in my system and to make sure the packet forwarder send data to the bridge i used the below command

sudo tcpdump -AUq port 1700

but no response. I followed the below link for trouble shooting
