Bluetooth Modem - BlueSMiRF HID

The BlueSMiRF HID is essentially the same board as the BlueSMiRF Silver but the populated RN-42 comes loaded with the HID firmware. HID, or "Human Interface Device," is the communication protocol used for computer peripherals such as keyboards, mice and joysticks. This makes the RN-42-HID a simple and powerful tool for creating wireless peripheral devices which can be universally recognized and used without the installation of special drivers. The manual included in the documentation below goes into more detail about the Bluetooth HID profile.

The remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer.

This unit by default acts as a HID keyboard, so if you want to similate keyboard entry wirelessly to a program on a pc, ipad etc then this is just what you need.

Do check out the comments on the Sparkfun product page, they are quite informative on how to connect and use the module. Also see the Arduino link at the bottom of the page.

Note: This is a single unit only. We recommend the purchase a USB dongle to interface to a computer if you do not already have access to a computer with Bluetooth connectivity.
