Not every Python hardware library needs a board: pynput drives your keyboard and mouse, Bleak your Bluetooth LE devices. Jumpstarter automates hardware tests.
How to choose:
- Controlling or monitoring the keyboard and mouse: pynput
- Bluetooth Low Energy devices, like sensors: Bleak
- Automated tests on real or virtual hardware: Jumpstarter
pynput controls and monitors input devices: the mouse and the keyboard. To send input, create a Controller and call its methods, like press(), release(), or type() for a whole string. To react to input, open a Listener with your callbacks in a with block and call join(). In a GUI app with its own main loop, call start() instead, so your code keeps running.
Bleak is a GATT client: it connects to Bluetooth Low Energy devices, like sensors, through one asynchronous, cross-platform API. Connect in an async with BleakClient(...) block and start your program with asyncio.run(). That's the recommended way, and the device disconnects even when your program is interrupted or raises. Scan the same way, in an async with BleakScanner(...) block.
Jumpstarter is an open source framework for hardware-in-the-loop testing on physical hardware and virtual devices. A person in jmp shell, a pytest script, and a CI pipeline all use the same APIs. Local mode needs no Kubernetes and suits one developer with the hardware at hand. Distributed mode runs a Kubernetes-based controller that leases devices, so teams can share them, including from CI. Write tests on the JumpstarterTest base class from jumpstarter-testing, which handles the connection for you. Set a selector for the device you need: the class connects from inside jmp shell, or leases a matching device outside it.
