adding bluetooth to pm3

I'm supposing to integrate a bluetooth transceiver on the pm3 board (on a new pcb) in order to allow easy integration with smartphones.
I still didn't investigated a lot but...

about the hardware:
it could be nice (but not mandatory) to maintain the ability to choose to communicate via usb or via bluetooth

about the software:
I wish to understand if is it possible to convert the actual usb protocol to standard 232 serial protocol able to be sent on a bluetooth transceiver.

So the question is: How much is it complicated to allow the arm firmware to communicate on an easy serial protocol? I know that usb is a serial protocol but i suppose there is a software layer on the arm delegated for the usb driver.

why not wifi? because wifi transceivers are too much expensive, software layer costs a lot of lines of code, and the power comsumption is very high.

Is it there someone interested to develope this part of code? may be (to be verified) i can send free board with bluetooth transceiver on it to the developer that successful do the modification.

Re: adding bluetooth to pm3

A question/problem: can the BT frequency interfere with the pm3 antenna ?

I think that bluetooth won't affect HF/LF antenna. See modern smartphones: they have lots of transceivers for GSM, 3G, LTE, Wi-Fi, NFC etc and they work good all together.

Re: adding bluetooth to pm3

bluetooth works at 2,4GHz, it is really far from rfid frequencies. no problem about this.
