Setting up Multitech Conduit Gateway for TTN

terrence · June 10, 2016, 1:25am

I am not doubting you, but where can I read up on this bug?
Thanks.

Lespagnol · June 10, 2016, 3:35pm

Hi terrence,

When you send a set uplink counter command the module returns OK but when you read back the counter the value has not been updated.

Start module
Send : mac set upctr 12
Receive : ok

But when you send a frame the sequence number is not 12.

This bug has been seen on every rn2483 0.9.5 and rn2903 0.9.5

@kersing Hi Jac are you going/willing to provide an ipk package for the latest version of the Packet forwarder? would be great to experiment with a private backend.

kersing · June 13, 2016, 4:31pm

@ajtalsma

Sorry, no, I will not be attempting to build the newest software for MultiTech conduits, the reason:

v2.2.0 - 2015-10-08

Removed FTDI support in makefiles to align with HAL v3.2.0.

As the MultiTech gateways are FTDI based it won’t be possible to run the newest versions of the HAL and packet forwarder on them. The new software requires SPI communications to meet timing requirements.

ajtalsma · June 14, 2016, 3:38pm

Ok thanks for the info. Does that mean the Multitech conduit hardware is obsolete with regards to the development of the packet forwarder? In other words, why buy this gateway if it won’t support future functionality/requirements?

diegogutierrez · June 8, 2017, 2:59pm

I’m at the same point, lora-pkt-pwd is running and registering to TTN. But the Lora server did not.

I want to join my mDot. Any suggestions?

diegogutierrez · June 8, 2017, 4:10pm

I am working with MULTITECH’s “MultiConnect Conduit IoT Starter Kit for LoRa Technology”. I have been able to connect to TTN by following the guide: https://www.thethingsnetwork.org/docs/gateways/multitech/aep.html

I have the following queries:

The kit comes with an mDot box node and it has stopped connecting to the Lora signal. It only connects when from mLinux I launch the lora-network-server but this causes my gateway to stop connecting to TTN.

So, when I run ttn-pkt-forwarder does the Lora Radio service launch? When I used the command sh installer.sh will the packet forwader and the server be installed?
MDot box firmware does not support ttn-packet-forwarder? I just want the mdot to detect the radio signal.

bickster1 · June 8, 2017, 4:27pm

I haven’t used my gateway in awhile. Sorry.

kersing · June 8, 2017, 7:12pm

Have you configured the mDot to use the TTN keys and frequencies?

The ttn-pkt-forwarders interfaces between the conduit radio and the network forwarding all valid LoRaWAN packets to TTN. No additional software in the conduit is required.

diegogutierrez · June 8, 2017, 8:29pm

I’ll be working on it, thank you so much.
Let’s Keep in touch.

Hello,
I have problem with Multitech gateway. I’m using ttn-pkt-forwarder with 2 uplink servers. One is for our private purposes, connected via semtech protocol. Second is for ttn network. Uplink messages is fully functional to both servers. Problem is with downlink messages. These messages are not sent to nodes. Messages have arrived to gateway, but ther are not sent to nodes.
There is a log from gateay:

lgw_receive:1165: FIFO content: 1 10 0 5 13
lgw_receive:1184: [2 17]

When I used default lora-packet-forwarder, downlink messages are fully functional, but there is a limitation to one network server, so I cannot expand my gateway to ttn network. Can you tell me, where can be a problem?

Thank you.

kersing · December 20, 2017, 12:30pm

The log you are showing does not contain any downlink message, just uplink. Is the gateway receiving downlink data?

davidhrbaty · December 20, 2017, 12:59pm

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.

davidhrbaty · December 20, 2017, 2:13pm

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.

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

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
Paul
