## About The Project
> ⚠️ **Important note:**
> This project has a strong dependency on the specific hardware and software configurations used. It is provided for reference only for those who wish to create a similar system.
[Go](https://go.dev/) script for acquiring and transmitting data and media stream from the various sensors mounted on the embedded system from the race car through cellular network.
### Features
- Collecting data from the modem, GPS, and sensors by executing [ModemManager](https://modemmanager.org/) cli commands
- Updating [LiveKit](https://livekit.io/) room metadata at regular intervals when changes are detected
- Creating and controlling an optimized [Chromium](https://www.chromium.org/) instance
- Capturing and sending various streams from [Chromium](https://www.chromium.org/) to the [LiveKit](https://livekit.io/) server
### Tech Stack
- [Go](https://go.dev/)
- [Chromium](https://www.chromium.org/)
- [LiveKit](https://livekit.io/)
- [ModemManager](https://modemmanager.org/)
### Hardware
- [Raspberry Pi 5](https://www.raspberrypi.com/products/raspberry-pi-5/) (8 Go)
- [SixFab 4G/LTE Cellular Modem Kit](https://sixfab.com/product/raspberry-pi-4g-lte-modem-kit/)
- [Battery UPS HAT](https://www.dfrobot.com/product-2840.html?srsltid=AfmBOooD28ApNQEqDY-Vkc-WCCOt0VZ2mOPo3arpIw6eJ0-mFeeHss7Z)
- MPU6050 sensor
- Various UVC Webcam, including Elgato Cam Link 4K
### Configuration
A `.env` file must be created with the information provided in `.env.example`.
All fields are required.
#### ModemManager
Grant the desired user the necessary permissions to partially control [ModemManager](https://modemmanager.org/).
This step is required if you want to use the [Go](https://go.dev/) script without running it with `sudo`.
```bash
sudo nano /etc/polkit-1/localauthority/50-local.d/50-modemmanager.pkla
```
```bash
[Allow mmcli]
Identity=unix-user:username
Action=org.freedesktop.ModemManager1.Device.Control
ResultAny=yes
ResultInactive=yes
ResultActive=yes
[Allow mmcli location]
Identity=unix-user:username
Action=org.freedesktop.ModemManager1.Location
ResultAny=yes
ResultInactive=yes
ResultActive=yes
```
```bash
sudo systemctl restart ModemManager
```
