[Multitech Conduit] Cannot connect mLinux 5.0 to loraserver.io

Hi all,

After upgrade Multitech conduit mlinux to version 5.0 and install lora-packet-forwader , lora-gatway-bridge ( https://www.loraserver.io/lora-gateway-bridge/gateway/multitech/).
I configurate global_conf.json in folder /var/config/lora-packet-forwader: ( lora server ip).
“gateway_conf”: {
“gateway_ID”: “008000000000A88X”,

The LoRa Gateway Bridge is installed on a separate machine.
I try to troubleshoot connect from server to gateway: ( gateway ip).

Loraserver return error:


Double check your GW ID : “gateway_ID”: “008000000000A88X”, in your global.conf file

vs “gateway_ID”: “008000000000A882" in your loraserver definition


I don’t see an error in your screenshot. If you only have one gateway, you will always see this output on that screen, the same when this feature has been disabled.

I recommend you to look at the Live LoRaWAN frames, that will show you the received / sent frames and will tell you if any data is received from your gateway.

Hi ric2498,

gateway_ID in global_conf and loraserver is same.

Hi brocaar,

Thanks for your reply. But can i received data without status connected from gateway?

Hi brocaar,

I cannot see any data from Live LoraWAN frames.

Please see the troubleshooting guide: https://www.loraserver.io/guides/troubleshooting/gateway/. It will help you to debug the gateway connectivity.

i had a simmilar problem… maybe it helps.

do you have a local_config file on the same or also another directory? i had one and the global_config was overritten by the local one. so the device did not connect to my loraserver but to another server (defined in the local_config).
