Dpropicweb tipped us to a new Open source Bluetooth stack for PIC24 and PIC32. For hardware, a PIC drives a cheap USB Bluetooth dongle using a USB host interface. The Bluetooth part is open source, unfortunately is also uses Microchips undistributable USB drivers.
- The code is really easy to understand, very well documented and really small.
- Designed to be extended and ported.
- Works straight out of the box with the PIC32 USB Starter Kit II and should be fairly simple to port to other PIC32 or PIC24 boards.
