Configuration of the Multitech Conduit on Packet Forwarder

[Rafael Dos Santos]

Hi,
when i restart the lora-network-server, i get a problem because the json file “global_conf” isn’t generated.
what can i do?

Do you have any messages being generated by the device?

What is the message from this command:
> /etc/init.d/lora-network-server restart

Is the MTAC-LORA card seated properly and being read? MTAC-LORA info should show on the dashboard in the bottom right corner.

Hi Jason,

the message is:

stopping lora-network-server OK
starting lora-network-server OK

and no problem with the MTAC-LORA

Rafael,

The global_conf.json file should be created in this directory

/var/run/lora/1/

It will contain the json that has been entered into the packet forwarder configuration text area when configured for packet forwarder mode.

Can you provide more details one what you have done or what you are trying to do?

[Rafael Dos Santos]

Jason,
Thanks I see the file now.

But I want to test if the packet forwarder can be LoRa to LoRa.
I think that can’t result.

How can i do LoRaToLoRa with the gateway?
Can I install 2 MTAC-LORA on the Conduit?

[Jason Reiss]

The MTAC-LORA radio can send and receive lora packets. With the correct settings the they can communicate.

The “ipol” setting is enabled when communicating with the end points.
The “ipol” setting is not enabled when end points are communicating with the gateway.

Two cards can be installed and used and two packet forwarder processes can be started. The network server will only use one card by default.

Thanks Jason

Jason,
another question, I have 2 x gateway and one end point. I want to transmit data from mDot to gateway and after that gateway to gateway.
because I have a rang problem and I want to use one gateway like a “relay”.

It’s possible to send data gateway to gateway from LoRa communication?

[Jason Reiss]

It would be “possible” to repeat the packet with one conduit, however there is no software available to support this.

This will only work with upstream packets. Downlink packets would arrive late.

[Rafael Dos Santos]

Ok, thanks Jason
I will try

[Rafael Dos Santos]

Jason,
do you know which file I need to edit?
Node-Red on the Multitech conduit, can solve my problem?

Thanks for your attention

[Jason Reiss]

There is no software available to support this. It would be a custom application running on the conduit.

Node-red could be used to listen for UDP packets from the forwarder and send them back to the forwarder with the key { “imme”: true } added to the packet.

For more details on downlink packet format see:

Thanks, Jason
