BLE_GAP_SEC_STATUS_UNSPECIFIED in ANCS application

[ppatierno]

Hi,

I developed an application for nRF51822 starting from ANCS example. All works fine but I have current scenario ... starting from a clean situation ...

1. Execute bonding between iPhone and device ... OK
2. Use device with an iPhone app ... OK
3. Restarting device with button pressed for cleaning device manager bonding information. Do nothing on iPhone. In this case iPhone has bonding information but they aren't on device
4. The iPhone try to connect to device but I see from trace BLE_GAP_SEC_STATUS_UNSPECIFIED status code

Why ?

Thanks, Paolo.

because the iphone sees the device address and uses the LTK it has for this bonded device. But the device does not understand anything from the iphone because it does not know that the iphone is bonded. When you say that the reset will clean the device manager bond information, what exactly does this mean?

I simple start my DK pressing the button 1. From code the application delete all bounded devices. However your answer is clear. Thanks ! I need to "forget" the device from the iPhone and restart bonding.
