No communication with LoRa node post setup

Greetings,
The lora-app-server UI works perfectly well which enabled me for creation of network server , service profie, device profile and to some extent application along with addition of device.

The problem:
I cannot receive any message from lora node (RAK 811) however it does receive a message(confirmation message) after transmission of data

Output @ LoRa node based on ABP configuration set using https://localhost:80808

Am I missing something?

Please check the loraserver logs. Nothing in the above logs relate to the received frame from your device. You also might want to check this guide: https://www.loraserver.io/lora-gateway-bridge/install/debug/.

And can you see an uplink going through your gateway ?

I apologise for my delayed response and thank you for replying , @brocaar @Clement

No I cannot see the uplink.
And for some reason Im failing to understand I cant start my lora concentrator(RAK 831) as suggested in setup guide I have linked the packet forwarder to the working RAK831 lora_gateway and made packet_forwarder as service.

I can see the frame counter when I run test_loragw_hal located at /libloragw which prior to packet forwarder installation didnt exist.

Sending packet #94, rf path 0, return 0
status -> 2:
TX finished
d9.40.0.0.0.0.0.5.0.9a.14.1.0.6.0.0.54.58.2e.54.45.53.54.2e.4c.4f.52.41.2e.47.57.2e.0.0.0.5f.end
+++
output I get when I run test_loragw_hal However I can only see the Rx led on glow once upon startup and then doesnt blink which was not the case prior to installation of packet forwarder.(May mean that I have messed up with something here too).

The loraserver , lora-app-server and packet-forwarder are running as services although packet forwarder tries to restart almost everytime stating failed to start concentrator so I went in for /opt/semtech/packet-forwarder/lora_pkt_fwd and after manually reseting the my concentrator I ran ./lora_pkt_fwd which gave me following log:

I have configured local_conf.json as follow:

/* Settings defined in global_conf will be overwritten by those in local_conf /
“gateway_conf”: {
“gateway_ID”: “XXXXXXXXXXXXXXX” /
you must pick a unique 64b number f$
}
}

and the global_conf.json is set as EU868 and with same gatway ID

mosquitto_sub -v -t “gateway/+/rx” //I am getting no log for this upon usage

journalctl -f -n 100 -u lora-gateway-bridge //Same for this no log

sudo tcpdump -AUq -i lo port 1700 //Same of this too

I have install lora-gateway-bridge, loragateway and packetforwarder too…

Where shoud I start from to fix this problem?

You’re problem is clearly coming from your gateway.

You have no log in server part because you don’t forward any message from your “offline” gateway.

Can you paste your global_conf.json file here ?

@Clement thanks for replying

@Clement
I did manage to run packet forwarder (/opt/semtech/packet_forwarder/lora_pkt_fwd/lora_pkt_fwd) and it runs perfectly too the Rx led of the RAK 831 board is up and it can receive the message from RAK 811 however:

at+mode=0
OK

at+set_config=dev_addr:ZZZZZZZZ&nwks_key:YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY&apps_key:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
OK

at+join=abp
OK

at+send=0,2,000000000000007F0000000000000000

OK

at+recv=2,0,0

this is what I get at the UI

and then if I go for confirmed uplink

at+send=1,2,000000000000007F0000000000000000

I reveive the confirmation after a dealy of like 5-6mins
and no data at live device data

and this mosquitto_sub -t “gateway/#” -v gives
