I have recently acquired a bluetooth development kit (TDK's blue2i + USB adaptor). I have successfully connected the serial ports and transferred and received the data at 9600 baud. I want to use the serial module in customized hardware. But the serial unit is very expensive (around 92 pounds). What alternative chips do I have at my disposal which will provide me with a serial - bluetooth interface? My only requirement is a bridge between uart (well, only RX/TX) and bluetooth protocol.
Since I plan to interface the chip with a microcontroller, I do not need a RS232 level converter of that sort either.
So which chips would allow me a bluetooth - I2C or SPI or Serial or USB for that matter interface? If I want to remove the serial interface also and just go for a simple command received via bluetooth, how can I do that with a micro-controller present in my circuit?
Any feedback much appreciated,
Thanks in advance,
