C# emulate HID clicker bluetooth

Question

I need some guidance on how or whether this is possible to achieve without a "server" application running on the pc. I have gotten as far as establishing a bluetooth connection to the PC, I would like to send HID commands to control a slideshow similar to how a clicker works.

Answer 1

The PDF outlined by this link is an excellent, detailed, platform-agnostic resource on sending HID commands via a Bluetooth connection. It talks about having your device set up as a server, and what the relevant commands to send over the link. So, to answer #1 - it is possible. 2 this document outlines how it is done.

Answer 2

while it is possible, as far as I know, under windows that would involve either

• using an external bluetooth HID module (like this http://www.instructables.com/id/3-Bluetooth-HID-Module-HC05-With-RN42-Firmware/)
• writing a semi custom bluetooth driver to appear as a HID device.

if you have an external HID module, it's easy, just talk to it via rs232 (serial), and it will send whatever you want, though you will need to buy some hardware.

it seems like you can get away with just patching the windows bluetooth driver instead of writing one. https://nadavrub.wordpress.com/2015/07/17/simulate-hid-device-with-windows-desktop/

If you have access to linux instead, using a already available library for that would probably be the safest and easiest.
