I just read the specs of the RF chips for the Nike+ and the receiver. It's not ANT, since it's not an ANT compliance chipset. (Either way, ANT isn't Bluetooth or 802.11). It's not Bluetooth, and it's not 802.11 anything. The only common factors it has with either, really, is that it operates on 2.4GHz.

No, the radio protocol it uses is a pretty straightforward protocol, that's proprietary to the Nordic Semi nRF24xx series. On the radio side, it appears to be a simple raw serial bit stream at 1MHz. This isn't going to be anything the BCM4325 can pick apart.

I suspect that the tiiiiny little chip to the right of the BCM module, seen in the face-up shot with the LCD removed, is the nRF2401A which is the Nike+ receiver chip. It can piggyback the same antennae that the BCM chip use.

As far as Bluetooth in the iPod Touch, it may be something that they add in software later. The chipset's already in place, and no physical changes are necessary. I'm not sure that Steve & co are happy with the idea of A2DP, because it requires the use of lossy audio compression to fit to stereo audio channels into the Bluetooth data channel. So that means lossy compression of an audio stream that's been previously compressed with another algorithm... which means reduced audio quality.

As for the other functions of the BCM4325... please also note that it's got an FM receiver and supports 802.11a (5Ghz WiFi) too. But those require additional hardware to support.

Thank god, the voice of reason!

Well hell. Just like my mama always said about Santa Claus. All talk, but nuthin' in the sack.

Seriously, just like everybody else, I wouldn't want to run into a Brute in a dark alley

Hmm. A lesson, perhaps, for Nano-Proprietary:

You can have a smaller piece of a much bigger pie.
Or you can have NO PIE AT ALL.
Your choice.

I don't get it. If you've got a radioisotope thermal generator on-board, you bloody well don't need the solar cells. Unless it's a teeny tiny RTG, but then it's hardly better than going without...

I just signed up to try to get on as a hardware developer. I'd love to get bluetooth and/or IR working on it. Put a mic on board, and use it as a bedside VoIP phone, etc.

You know what? I owned one. The second model, even, so you didn't have to hold the ass-end of a taco to your ear to talk.

It sucked as a cellphone AND as a game platform. Even at $20, and with $2 games, it's not worth it.

Good grief. Ignoring all the comments in the vein of religious warfare:

There's a reason the bitrate is so slow. The camera is designed to output a raw, low-level flexible serial protocol. It outputs a single bit at a nominal 3.3v, on one edge of a clock sourced by the host device.

In this design, the clock is generated by, and the data is read by bit banging. The IOs are used as general purpose IOs, and programmed and read by the CPU, then the data is deserialized in software, and then whatever else has to be done to recover the video stream.

Bit-banging is not fast. At all. A productized version of this would likely connect to the GBA slot, and leave the DS slot available. Data rate wouldn't be a problem then.
