Create a simple lora mesh network based on the open source RadioHead library, with arduino uno and esp32 modules equipped with LoRa tranceivers. Publishes the information collected by the nodes on a web dashboard via MQTT events.
This program should set up a LoRa mesh network. Depending on its node ID, it will wait for incoming LoRa messages and reply an ACK message to the sender. If the node ID is #1, it also relays the message via MQTT events to a public cloud broker. All other nodes will send hello messages to the other nodes on the network waiting for the ACK. If any node is out of coverage, the entire network is in charge of rerouting the routes so that the messages continue to reach their destination.
It was designed to work with two modules:
- Arduino UNO + Lora Shield transceiver (https://docs.arduino.cc/hardware/uno-rev3 + https://emging.com.ar/producto/shield-emging-lora-v1-1-915mhz-rfm95w/)
- Heltec ESP32 LoRa Wifi v2 (https://heltec.org/project/wifi-lora-32/)
Simple Server for a Dashboard. It's shows MQTT incoming messages.
For the deployment of the solution, you only have to upload the node code to each device taking into account the previously assigned node ID. You must also configure in both codes the MQTT Brocker and Topic to use.
To deploy the dashboard, follow the instructions below:
$ git clone https://github.com/chewydc/PFI_UADE.git
$ cd PFI_UADE
$ cd Dashboard
$ npm install
$ npm start
