Sending a Custom Packet Over LoRa On-Demand

[Brice LaVie]

Hello,

I am trying to deploy an application in which there are several “client” MultiTech Conduit AEPs and I want to be able to encode data into a custom packet and send it, over LoRa, to a central MultiTech Conduit AEP to then parse the packet and aggregate the data. All Conduits will be the same model.

How would this configuration be achieved in the simplest possible way? Is there a way to send a custom packet to the internal MQTT broker on the client that, in turn, sends the packet over LoRa to the “server” Conduit that can then be decoded using software that is listening on a topic over MQTT?

Thanks

Normally packets scheduled and sent by the network server will be target at the end-devices. These packets are transmitted with reversed polarity so that other gateways do not see them and they do not interfere with end-device uplinks. The network server schedules transmission and regulates the duty-cycle of the gateway transmitter where required by law.

The MQTT message to the network server can only be used to queue packets to end-devices. RAW lora messages cannot be queued or transmitted.

One possibility is to use an MTAC-XDOT card as a secondary transmitter configured as an end-device connecting to the central Conduit via LoRaWAN.
