Bluetooth

Bluetooth is a short-range, wireless technology, popular for its Personal Area Networking capability. Bluetooth harware is provided on all iPhone platforms and many iPod Touch platforms. Apple has severly restricted the functions of Bluetooth to the end-user, for seemingly no reason, as the hardware supplied is capable of most if not all current bluetooth 2.0/2.1 functions.

With iPhoneOS 3.0, support for 3G internet bridging and A2DP over bluetooth has been added, however the file sharing OBEX protocol is notably still missing.

Access

Developers have been able to successfully access and interface the Bluetooth hardware to achieve an OBEX solution, however this is still quite underground. The device nodes of relevance here, are

• /dev/uart.bluetooth
• /dev/cu.bluetooth
• /dev/tty.bluetooth
