Hi Matthias, THATS IT !! If i change the CoD e.g to 0x2540 or some other CoD's i found, it will be discovered by the iPhone. I now have to find the CoD for SPP within MFi documentation ..... Thanks for your help and have a good day ! Cheers, Bernd -----Ursprüngliche Nachricht----- Von: Matthias Ringwald [mailto:mringwal@inf.ethz.ch] Gesendet: Mittwoch, 20.

I've recently wondered why the Duo Gamer controller (a MfI device) shows up for a split second as headset. Maybe that's why. I'm not a member of the MfI, but I assume the CoD to use should be documented, too. Best Matthias On Mar 20, 2013, at 9:31 AM, Bernd Lemp <b.lemp@schmid-electronic.de> wrote:

Hi All,

i’m a complete newbie to iPhone and Bluetooth connectivity. So sorry for maybe asking such a simple/stupid question !

We do have a little sensor with a Bluetooth 2.0 + EDR module (iPAN1321) that is already working fine with Android. We now have to extend this to work with the iPhone 4/5.

If I try to find the sensor from the iPhone (Settings/Bluetooth) the sensor is not showing up there, doesn’t matter how I configure (Secure-Mode 1 or 3) the Bluetooth module. Is this normal behavior ? I can start a BT-RF connection from the Bluetooth module to the iPhone and also start with IDPS then. Is this the normal way to start communication between the iPhone and a Bluetooth device ? Isn’t it possible to do it the other way around, so let the iPhone search for the Bluetooth device within Settings/Bluetooth and then start the BT-RF connection from there ?

Your help would be really appreciated !

Thanks in advance, Bernd
