This node collect data through LoRa from several edges-nodes or smart-meters.

Clone
git clone https://gitlab.com/electr-nica/2020-medidores-mesh/firmware/middle-node -
Go to the project folder
cd middle-node -
Build
source make.sh -
Run
sudo docker start node
The serial port to LoRa is set to dev/ttyUSB0 by default, you can change that in the config.json file before build or inside the container file system.
-
To view the logs of the container
sudo docker container node --follow --since 0m -
To stop it
sudo docker stop node
The hat uses the UART0 as the way to communicate with the LORA module, so it is necesary to make some adjustments to the rpi in order to use it tha way.
-
Open
sudo raspi-configand selectInterface Optionsthen, at the optionP6about "Serial Port" selectYesand lastyNoto the presented options. That to allow the usage of the UART for general purpose. -
Edit the config file
sudo nano /boot/config.txtand enable the uart verifing the lineenable_uart=1, and disable the bluetoothdtoverlay=disable-bt -
Reboot the rpi
sudo reboot. -
Verify that "json/config.json" at middle-node is set to the serial port related to the uart, that could vary depending on what rpi you are using: serial0,AMA0 or S0. Try and test.
-
Verify the serial port in the Dockerfile.
The folder json contains the config file where you can modify the default values for parameters.
Before build the container make sure the dockerfile contains the timezone corresponding to your location.
To develop you should not execute the make.sh file which is used for production purposes. Instead, just develop through the source files (src folder) and a virtual environment of python Remember to install the requirements before run.
tip: run from the parent folder because all path files are relative to this (ie. python src/main.py)
