    Hi,

    I am looking to get advice to find following:

    1) A very compact cheap bluetooth receiver (only bluetooth data receiver no need to receive audio).

    I understand that there tonnes of such receivers in market but I want only data receiver so I don't want to spend more on bluetooth audio receivers.

    Can some one please let me know smallest cheapest bluetooth data receiver chip/IC in the market?

    2) A minute-small vibrator which can be connected to the above bluetooth receiver - cheapest. Also, cheapest smallest power unit to power the vibrator circuit - may be coin cell...


    Idea is, on sending command from any bluetooth transmitter, the above bluetooth receiver will receive the command and ask vibrator to vibrate.

    cheapest bluetooth modules I can think of are the HC05 modules. But these transmit UART data. So you would need more circuitry to control the vibrator.

    yes depending on the hardware selected (bluetooth chip/IC and vibrator chip) - I will have to get the circuitry designed...

    check out the HC05 and HC06 modules, you will then need a small MCU, something like an ATtiny2313 or 8051 with serial port is more than enough. You can use a transistor to control the motor.
