8001 bond

[jixing.zou]

Hi,

I want to realize the function of bond, I use "lib_aci_bond(180/* in seconds */, 0x0050 /* advertising interval 50ms*/);'\",.When I click the connect, it can connect , but no the pair command box appear.

Something I doesn't configure??

Hi,

When using the ACI Bond command, the device is in pairable/bondable mode, however the initiative to pair or bond remains with the central role device.

In case of iOS and some other operating systems implementing Bluetooth low energy, the pairing process will start only when an error occurs on reading or writing to a Characteristic. See the Apple accessory design guidelines ( developer.apple.com/.../BluetoothDesignGuidelines.pdf) in the Section on Pairing.

To allow the pairing to be done and the encryption to be used successfully you need to do the below steps

1. Use ACI bond
2. Set security level of the device in Security -> Device Security to "Security Required"
3. On the iOS app, you now need to Read or Write to a Characteristic that is present on the nRF8001 GATT table, at this point the Pairing popup will appear on the iOS device.
4. After pairing is successful and the link is disconnected, Read the dynamic data containing the security information using ReadDynamic data, and store it.
5. If the nRF8001 is reset or powered off, it will lose the dynamic data containing the security information. This dynamic data can be restored using the the stored Dynamic data and the WriteDynamicData command.

Look at the "ble_proximity_template" project in the Bluetooth low energy SDK for Arduino as a example for these steps.
