I try to build custom controller and now searching for bluetooth hid module. Which BT HID module compatible with arduino? (not bluetooth serial)

List of some modules:

  • BlueSMiRF HID - from sparkfun, expensive (based on rn-42, also available RN-42-EK evaluation board) ✔ compatible
  • HM-10 bluetooth module - around $10 (aliexpress), based on cc2540 ht tp://www.ti.com/product/cc2540
  • HC-05 Transceiver Module - less $10, maybe supports HID after firmware upgrade(??)
  • Bluegiga wt12
  • Bluefruit EZ-HID from Adafruit ~$20 (suggested by mwwalk) ✔ compatible

Thanks

I'm not entirely sure from your question if you want just the module or a whole breakout board. If the latter, try this from adafruit. It can very easily do his either as mouse or keyboard and is well documented and supported so I think this would be much easier to get running initially. http://www.adafruit.com/products/1535

HC-05 HC-06 and, for example, RN-42 HID are the same looking on hardware design.

Only difference is in firmware.

For educational purposes you can dump firmware from RN42HID and flash HC-05/06 module and you've got a HID module.

The difference in costs of the HID modules is that CSR IDE costs $3000 per licence + developer seat, and when someone invests in developing wants the incomes to come.

Byron's blog will guide you, you need a SPI programmer, but you can use Arduino as programmer/debugger. And you will need blueflash software to backup some info from Your module (calibration of crystal for example, and IDS/MAC/serial) than you can flash the RN firmware, and you have exact copy of RN, last thing is to restore the settings saved from your original firmware.

Just Google it, here is not much place to put all the data and images.

But yes it is possible.
