🔹 Software Setup Guide for FM350GL 5G Modem

Get your Fibocom FM350-GL 5G modem up and running quickly with our open-source Linux GUI tool from the RxTxSemi FM350 Connect repository. This free tool offers serial port monitoring, APN configuration, real-time signal status, data usage tracking, and speed monitoring – perfect for 5G modem Raspberry Pi software setups and Linux-based SBCs.

Requirements: Linux kernel 6.11-rc1 or newer (native support included; older kernels may need patching). No Python dependencies required – download the prebuilt app from Releases.

Quick Start on Linux/Raspberry Pi:

1. Download and run the GUI app:

   wget https://github.com/RxTxSemi/RxTxSemi_FM350Linux/releases/latest/download/rxtxsemi-fm350
   chmod +x rxtxsemi-fm350
   ./rxtxsemi-fm350

2. Grant modem access (add user to dialout group):

   sudo usermod -a -G dialout $USER
   newgrp dialout

   (Log out and back in.)

3. Configure udev rules to avoid interference (create /etc/udev/rules.d/99-fm350.rules with: ATTRS{idVendor}=="0e8d", ATTRS{idProduct}=="7127", ENV{ID_MM_DEVICE_IGNORE}="1", then reload: sudo udevadm control --reload-rules && sudo udevadm trigger && sudo systemctl restart ModemManager).

Note: Windows setup uses standard USB drivers (via Device Manager). For Raspberry Pi, follow the Linux steps above. Full docs and community support in the repo.
