White-list with "Just works" simple pairing

[BohanLu]

Hello, 

We use nRF52832 with SDK-11 as peripheral in our project. We want to utilize white-list feature to limit the connection establishment. I have studied HID Mouse example, and the example uses MITM protection. It would trigger the pairing request in remote device, and if we want to clear the white-list limitation, we not only need to remove the white-list in our device, but also un-pairing the device in remote part.

I wonder if we could use "Just works" simple pairing with white-list to avoid this. Currently, we enable the white-list feature by writing a specific value to the characteristic of our device.

Any advice and suggestions will be appreciated.

This will also work with device manager. I do not understand why you say the HID mouse example is using MITM, the define is:

#define SEC_PARAM_MITM                  0                                           /**< Man In The Middle protection not required. */

Maybe what you mean is that you only want to pair, but not bond? Then that is controlled by:

#define SEC_PARAM_BOND                  1                                           /**< Perform bonding. */

Hi, Kenneth

I apologize for mixing the MITM, pairing, and bonding. Maybe, as you said, I should ask if I could use white-list with pairing only and WITHOUT encryption and bonding.

Thank you

I don't expect you will be able to do that. Pairing is mainly used for a temporary connection with encryption, while bonding is intended for long time persistent connection with identity and key exchange. You would not need to have any identity exchange for a temporary connection.
