This project is highly hardware / software dependant and as not been tested on other component expect mine :

• Raspberry Pi 5 (with Ubuntu 22.04 and ModemManager deactivated)
• Quectel EC25 Modem (preconfigured in ECM mode, with an "Orange" SIM card)
• GoPro Hero 12 Black
• Elgato CamLink 4K

The current user need to be added to the "dialout" group to allow communication with the modem's serial ports without sudo :

sudo gpasswd -a username dialout

1. Clone the project and install dependencies :
