central whitelist function

[helen]

Hi

         Which example Implement the central whitelist function?Is the whitelist of the center mainly used to connect the slave device which address is the same as the address in the whitelist of central?

Hi

In the nRF5 SDK v12.3.0 (which is the latest SDK supporting the nRF51 series devices) the ble_app_hrs_c and ble_app_rscs_c example projects both support whitelisting on the central side and can be used to whitelist devices based on the address of the advertising devices for example.

Best regards,

Hi

      1、Can the connection between the center and peripheral be established in the shortest time by using the whitelist?

      2、I found that using UUID filtering, address filtering, device name filtering and appearance filtering can match the connection，Is whitelist connection established faster than them？If so,How to implement the code of the center and peripheral?

Hi

Whitelisting doesn't have anything with the connection time to do, so if you're content with using UUID, address, or device name filtering that's fine too. In order to minimize connection time you can reduce connection interval, as well as setting scan window and interval to the same values to let the central device scan as much as possible. You can also set the advertising interval low to advertise more often if you can edit the parameters in the peripheral as well.
