Using some hardware (a couple of different options currently) and a piece of software running on the ‘Server’ machine – any devices which support Bluetooth LE HID can then receive the keystrokes.
With a LOT of help from @bbx10 and others on this forum we have got a pretty full functioning windows app and RPC server which allows you to use a nrf52840 express as a Bluetooth Keyboard/Mouse emulator.
We have a command line application and the beginnings of a Windowed application for sending keystrokes from one device to another. Our main reason for doing this is to allow individuals we support (such as Mark https://www.youtube.com/watch?v=_Ox94YrYtGo&t=22s) who have to operate one computer with a dedicated access solution to access another machine; work computer for example. But – we know others want to do the same thing for other reasons (for example as a replacement to Synergy, or a Wireless KVM).
We would LOVE to try and iron out the bugs (e.g. keyboard layouts) and add a windowed application to track mouse movements to send that over to the feather..(pop your issues here: https://github.com/acecentre/RelayKeys/issues) So if you want to help out please do. Code is currently in Python.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
