I work with servers and I have a need for a custom keyboard. It would have about 100 buttons (keys), each would send an ascii string to the server. I need it to be wireless because I need to close the cabinet.
Im looking for a wireless usb dongle receiver. It needs to id itself as a keyboard on boot. I think Im just not searching for the correct terms. Can anyone point me in the right direction, does something like this exist?
Yes I know there are certain keyboards with macros etc, that I could program these string into. and some other software based solutions. This is for a high security data center application and most of those devices are not allowed.
There have been many many implementations, but this is the one I remember by name:
https://github.com/tmk/tmk_keyboardNote: If you need specific examples of a wireless implementation, there are projects that add Bluetooth to the TMK base controller. You can probably also roll your own protocol using some Nordic transceivers.

If your usb dongle identifies as a keyboard, then anyone can send keyboard data to it, bypassing security. You need to rethink your solution.

It's obvious - anybody who plugs USB keyboard into PC or server, can send keyboard data to it. He do not need to rethink solution. He need wireless keyboard with secure
wireless connection. USB can stay as it is.
[edit] In case
physical security of keyboards needed, then there are solutions as well:

disregarding high security and wireless key stroke injection conundrum.
another open hw open fw keyboard designs are the ones from input club.
https://github.com/kiibohd/pcbhttps://github.com/kiibohd/controllerthe controller fw has some support for Nordic semi's bt ?cs.
some options to start you off:
- HHKB Pro2 with Hasu BT Controller upgrade, which makes it programmable bluetooth keyboard. simple mod :
but not cheap.
- Anne Pro, BT has macros (but a bit ?), also cheaper. <http://www.obins.net/>
- Or if you just want to build a simple bluetooth hid thingy<https://www.adafruit.com/product/1535> is a quick start.
Yeah - for security reasons, I would not implement that as a standard keyboard, but as a completely custom controller with encryption.
