# IoT Platform
|
|
|
|
## Docker
|
|
|
|
First install DockerDesktop and `docker-compose`:
|
|
|
|
- https://www.docker.com/products/docker-desktop/
|
|
- https://docs.docker.com/compose/install/
|
|
|
|
Then you can export a path to mount as a volume and spin up the containers:
|
|
|
|
```sh
|
|
export DATA_DIR = /some/path/to/mount
|
|
docker-compose --file software/container/docker-compose.yml up
|
|
```
|
|
|
|
### Mosquitto
|
|
|
|
```sh
|
|
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](./software/flow/README.md)!
|
|
|
|
## 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"](https://docs.heltec.org/general/view_limited_technical_data.html#esp32-lora-series).
|
|
|
|
### 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`:
|
|
|
|
```sh
|
|
pip install esptool
|
|
```
|
|
|
|
### Find the port
|
|
|
|
Usually you can find the used port using `esptool.py`:
|
|
|
|
```sh
|
|
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/
|
|
|
|
|
|
```sh
|
|
esptool.py --chip esp32s3 write_flash -z 0 ~/Desktop/GENERIC_S3-20220117-v1.18.bin
|
|
```
