Hi,
we would like to use the Iphone touch for display external data over bluetooth.
This is what we want to do:
- Have a own App
- Connection over bluetooth

The simplest system could be an Temperature and Humidity sensor with microcontroler and bluetooth module. Data should be send in SPP (serial Port Profile).
Now I have seen that SPP profile is not available on Iphone or Ipod.

Is there a chance to connect over other way and bluetooth ?

Do have anyone tip or know-how to do that and is there a chance
do make app legal for App store ?

Thanks, for many helps !

    it's not possible... the bluetooth profile is limited to tethering and audio...

    The iPod Touch does not allow BT wireless tethering, only PAN (allowing other iPod Touch users to game wirelessly together).

    Unfortunately there is no capability to transfer data through BT, only to allow audio transmission through car stereos and home theater equipment.

    the profile is the same as the one on the iPhone, so it is technically capable, but not accessible...

    I may be possible since there are BT barcode readers that work with the iPad via the HID profile.

    HID Profile is a "Human Interface Device Profile", this allows connections between bluetooth keyboards, and similar devices. It's basically a "human convenience" that lets a user make input through another device.

    The PAN Profile ("Personal Area Network) is a profile that can actually transmit and receive data. The data though is limited to peer-to-peer gaming (games that can be played with others in the vicinity). A good example is the Rock Band multiplayer, where players join up using Bluetooth (and not Wi-Fi, to prevent lag).

    I believe there isn't any reverse HID applications (remotely using the HID from the iPod), most app that do that are wi-fi transmitted, since there's no need for a long, direct, connection. Examples are the Apple Remote, ADT Security, and OnStar. These all allow you to access your devices that are kept on your wireless signal (OnStar uses some sort of cell phone reception to put your car on a network).

    The "Apple authentication chip" sounds like the SIM card in an iPhone. No SIM chips in the touch.

    BTW, why don't you give this one a rest? The touch is not going to be doing data transmission via Bluetooth anytime soon.

    Development of an iOS bluetooth module are almost commercially available - and yes, even with this, you still need to follow the Apple approval norm for Apps - check unagi.net or email to willow@unagi.net with any questions

    Hi,
    any news to this topic?? I'm gonna to solving a very similar problem. My goal is to bring different sensor via BT on the iPhone/iPad. HID profile is ok for me, because the data rate is very low. Has anybody experience with suitable modules with HID working on IOS devices?
    Thanks for the discussion.

    "any news to this topic??"

    Not a feature of the ipod touch.

    There is no way to know what will happen in the future, unless Apple announce - which the very rarely do.

    Speculating on unannounced products is not permitted here.
