How to use bluetooth for data transmission

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 !

iOS 4

I looked for the profiles on http://support.apple.com/kb/HT3647
HID device is with the actual ios for Iphone and Ipod touch available.

If the bluetooth device will show as HID device can be easily connected ?

Iphone or Ipod can receive data from the bluetooth device ?

Is HID profile also usable to send data to the bluetooth device?
For example touch button an Iphone App will send datacode to HID device, Device then turn on for example an led ?

Please post if anyone have done such App or function.

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).

I have seen applications with barcode readers. They are connected as an keyboard and send the bar code like a keyboard to the Iphone.
Has anyone idea if HID can send code or Information to the keyboard ?

Receive Data could be possible like keyboard keys, but sending must also be possible for our application.

Is PAN better way or is it not possible to connect any other device than two Iphones over PAN ?

Want use bluetooth because of Power consumption and price of bluetooth modules.

Anyone other idea ?
