Ok, this might just be a dumb question, but I was wondering if Bluetooth follows TCP or UDP protocol? From my knowledge of network protocols (which isn't much), I would say that it doesn't follow either of those two and that there is some kind of specific bluetooth protocol that exist. I have one more question...what protocol does the bluetooth functionality in the GameKit in the new iPhone OS 3.0 follow? I haven't looked through every single word of the apple documents yet, but so far, I haven't been able to find it.

Bluetooth is a standard wire-replacement communications protocol primarily designed for low power consumption, with a short range based on low-cost transceiver microchips in each device.
Advantages of Bluetooth ProtocolsBluetooth offers economic wireless solutions (both data & voice) for short distances. It is used in the mobile and stationary environment. There is no setup file to install the Bluetooth; it is an inbuilt device. Global technology specifications are used.
The protocol architecture of the bluetooth consists of following in a bluetooth protocol stack: Core protocols consisting 5 layer protocol stack viz. radio,baseband,link manager protocol,logical link control and adaptation protocol, service discovery protocol.
TCP and UDP are transport level protocols whereas Bluetooth would be a lower level protocol. Thus you could use TCP or UDP on top of Bluetooth just as you use TCP and UDP on top of Ethernet.
