I'd like to add bluetooth 4 capabilities to a dsPIC33 based y, system I already have. However, I don't want to buy a fancy/expensive bluetooth stack.
I don't need to send a lot of data from the PIC over BT, so a UART tunnel is one possibility.
If you have access to an available HCI stack that I can use on the PIC, that is ideal.
