UDK mDot Not Joining mLinuxConduit

[Ashu Joshi]

I have gone over the steps over and over again. And trying to get teh mDOT UDK to communicate with the mLinux Conduit as described here: http://www.multitech.net/developer/software/lora/getting-started-with-lora-conduit-mlinux/

I don’t see any log file for the lora-network-server on Conduit but when I grep on the running process – I do see the lora-network-server is running.

I simply cannot get it to work. The firmware on UDK/MDOT issued by ATI command is 1.0.8. This is the output on the debug console of the UDK:

Can you share your configuration?

On mDot
AT&V

On Conduit
Contents of /var/config/lora/lora-network-server.conf

Also you could try these commands to run the network server manually and see if there are errors in starting

> /etc/init.d/lora-network-server stop
> cd /opt/lora/
> ./lora-network-server -c /var/config/lora/lora-network-server.conf

Hello Ashu

On the mLinux Conduit can you please issue opkg list | grep lora
and post the results.

[Ashu Joshi]

Steve – here is the list of opkg:
root@mtcdt:/var/config/lora# opkg list | grep lora
lora-network-server – 0.0.9.2-r0.0
lora-packet-forwarder – 1.4.1-r8.16
lora-query – 0.0.1-r0.0
root@mtcdt:/var/config/lora#

[Ashu Joshi]

Jason:

I have tried both ways:
1. Private – by setting network[“public”] to false and AT+PN=0
2. Public – by setting network[“public”] to true and AT+PN=1

The results below are with public

Steve: I tried running from the command line as you suggested, I have copied the output. Important to note that this combination was previously working with the TTN so it had the Packetforwarder setup. I changed it back for normal network server

You will want to update the lora-network-server to 1.0.8
See the downloads page. This will also fix the init script that was modified for TTN.

Jason – thanks – that did it – worked like a charm – upgrading the lora-network-server. Thanks!
