Serial-Studio GPL Full-Features Patches

English | 中文

This repository holds a single Git patch that unlocks the driver panels, Console Export and MQTT support in a GPLv3 build of Serial-Studio v3.2.7.

The patch produces a GPL binary versioned 3.2.7.1 to distinguish it from upstream Pro/GPL releases.

What's unlocked

• UART / Network / BluetoothLE (already in upstream GPL)
• Audio input driver
• CAN Bus driver (Qt SerialBus, needs CAN hardware to enumerate devices)
• Modbus driver (TCP + RTU)
• USB raw transfer driver (uses libusb)
• HID device driver (uses hidapi)
• Process driver (stdin/stdout & named pipes)
• MQTT publisher/subscriber (uses Qt6::Mqtt)
• Console Export to file — synchronously writes per-device .txt logs to WorkspaceManager.path("Console")/<projectTitle>/yyyy_MMM_dd HH_mm_ss[_deviceN].txt

See PATCHES.md (added by the patch) for the full inventory, build prerequisites, and the list of features that stay Pro-only.

How to apply

# Clone upstream Serial-Studio at the v3.2.7 tag
git clone --branch v3.2.7 --depth 1 https://github.com/Serial-Studio/Serial-Studio.git

# Read PATCHES.md for the full build prerequisites (Qt 6.9.2 + extra modules,
# hidapi, libusb, Qt MQTT from source) and then configure as usual:
cmake -S . -B build -G Ninja ^
