Maybe this could be related, although it’s an old thread: http://lists.apple.com/archives/bluetooth-dev/2013/Aug/msg00023.html On 02.03.2014, at 21:01, Erskine Brown <erskine.brown(a)gmail.com> wrote: > We are seeing intermittent periods of failed BLE connectivity. > > I am able to reproduce this on a mac mini by streaming audio to the device using the example heart monitor app. Simply run the app and an example heart rate peripheral, we have tried with CSR and TI.

A BLE peripheral can only accept one connection at a time - so, if you are already connected to a phone, you won’t be able to connect with a second phone before disconnecting the first link. A typical solution to this problem is a button on the peripheral that allows disconnection of all existing connections. After you verified that there is no existing connection (does it work when you switch the old iPhone off?), and the problem is really pairing-related, I would suspect the issue on the peripheral side. Maybe the code on the peripheral prevents connections from unpaired devices once it is paired. You cannot forget the device on your iPhone programmatically. However, you could add an additional characteristic to the peripheral, that, when written, deletes the pairing on your peripheral.

Dear Etan, I have a doubt related to reconnecting the peripheral with Bluetooth Central. Presently ,I am working on BLE project. In our project,we are connecting to the Bluetooth peripheral to protect our things(like bag,laptop,etc).And keep those things under our surveillance. I found an issue that,when ever I tried to reconnect the already paired tag with Central,that tag will not blinking the tag alarm and not getting the tag battery level. When ever I removed the pairing (previous bond) with phone,then it is working fine. In this scenario user will go into confusion state,because of forget the device for next usage, Is there any other solution,instead of forget the device every time for reconnecting with tag. Is it possible to forget the device from our application programatically. As a fresher, I am very proud to say,I am completed the BLE project with your guidance till now. I have this pending issue. Please give help me in this scenario. _______________________________________________ Do not post admin requests to the list. They will be ignored.
