Docker
First install DockerDesktop and docker-compose:
Then you can export a path to mount as a volume and spin up the containers:
export DATA_DIR = /some/path/to/mount
docker-compose --file software/container/docker-compose.yml up
Mosquitto
mosquitto_sub -h localhost -t '#' -p 1883
mosquitto_pub -h localhost -p 1883 -t '/' -m $(date --utc +%s)
Grafana
You can login to Grafana: http://localhost:3000/login (admin:admin)
Node-RED
NodeRed is running here: http://localhost:1880/
A simple introduction to Node-RED can be found - along with the nodes / the code - in this repository, please have a look!
Hardware
We are using HelTec Automation Wirelsess Sticks ESP32 Dev-Boards.
PinOut
The PinOut of our version 3 modules can be found here: https://docs.heltec.org/en/node/esp32/dev-board/hardware_update_log.html#wifi-lora-32-hardware-update-logs
License
For some parts of the Heltec board you need a "license".
USB-C
Our HelTec Automation Wirelsess Sticks ESP32 Dev-Boards already have USB-C. But they do not support Power Deliver (PD). If your computer tries to do PD, just plug a cheap USB hub between the board and your computer.
Arduino IDE
HelTecs GitHub repo can be found here: https://github.com/HelTecAutomation/Heltec_ESP32
I had to install VCP Drivers, first: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads
You can add their Board Manager to the boards managers URLs: https://github.com/HelTecAutomation/Heltec_ESP32/blob/master/library.json and find their libraries in the IDE (Sketch -> Include Library -> Manage Libraries... Search for "heltec esp32").
These boards are already V3 boards, so be careful selecting the right board and port (VCP).
Install esptool
Esptool is a Pyhton program to flash ESP32. As it's a Pyhton tool you can install it using pip:
pip install esptool
Find the port
Usually you can find the used port using esptool.py:
esptool.py write_flash_status --non-volatile 0
Using MicroPython
Download the firmware: https://micropython.org/download/
Flash it using esptool: https://micropython.org/download/GENERIC_S3/
esptool.py --chip esp32s3 write_flash -z 0 ~/Desktop/GENERIC_S3-20220117-v1.18.bin
