Setting up Multitech Conduit Gateway for TTN

Please learn how to format forum messages so people can read them. Do not just dump a lot of text in a message and expect us to sort it out.
Your gateway is not receiving any downlink data (at least not in this partial log). Just uplink (node to back-end) traffic which is forwarded according to the log. If you are receiving downlink data (back-end to node) the counters in the [DOWNSTREAM] section (apart from PULL_DATA which is just a heart beat) would be <> 0.

Hello, sorry for previous format of my message. My mistake.
In DOWNSTREAM section is PULL_DATA sent:3 , so this is data which network server want to send to end node,or not?
My end device is Adeunis RF field tester. If I send data through basic multitech lora-packet forwarder, I got ack back to Adeunis tester. Buf If I send data throuth ttn-pkt-forwarder, I never got ack back to Adeunis tester. Configuration of multitech gateway for both packet forwarders is the same.

There is a log from basic lora packet forwarder from multitech:

I thnik, that problem is, that the ttn forwarder listen to downlink messages only from ttn network and not from my own network server.

kersing · December 20, 2017, 5:43pm

No, that is the gateway sending a keep alive to the back-end. Not downstream data.

I am not seeing any indication in the log you’re quoting that the uplink packet is forwarded to your server, so I do not expect that server to send downlink data.

Hi kersing

would appreciate if you could help with the issue connecting Multitech Conduit AEP to TTN, bascially I setup up by following the guide athttps://www.thethingsnetwork.org/docs/gateways/multitech/aep.html.
However once started, I always get error message saying that connection to server failed, such as:

15:33:19 ERROR: [TTN] Connection to server “thethings.meshed.com.au” failed, retry in 240 seconds

Meanwhile I can ping the URL from the conduit, I tried both DHCP and static IP but no difference made. Thought this might be related to DNS, I double checked and confirmed that 8.8.8.8 has been setup as DNS server, and I even put the server IP to /etc/hosts but still no success.

The conduit FW is version 1.4.3, with AU915 Lora mCard.

@leoy you will have to jump into the local_conf.json file and add a server port 1882

In /var/config/lora/local_conf.json

Look for the line starting with “server_address” and change the server to

“server_address”: “thethings.meshed.com.au:1882”,

Save and reboot, should work for you now

cheers
