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.
