I am trying to implement my own Bluetooth HID device (a kind of custom game controller), but am having trouble finding what I am looking for.
I have only come across two solutions which seem slightly expensive to me based on the task. The two solutions are the RN42-HID (click buy to see the HID version), and the Bluegiga WT12. Both seem expensive to me for my purposes. I am wondering how typical Bluetooth keyboards and peripherals which use the HID profile without installing anything do it. Are there other modules out there that I am unaware of?
Just to be clear, I do not want any software on my PC which translates, say, a serial Bluetooth connection's commands to HID commands. I strictly want the Bluetooth module to be recognized and operable as an HID device.
