Auto-connect central with the same peripheral after first connection even if there's more peripheral near

[Eng Eink]

Hello there,

I'm developing a device who will use two NRF52832(ANNA-B112 Module). They will communicate as central and peripheral.
But i'm facing a problem, i need to after the first connection between the peripheral and the central, the central stores a unique identification to connect only with this first device that has been connected on the first connection. 

For example:

I have 1 peripheral(A) advertising, then my central connects with peripheral (A) after that i disconnect both and turn on a second peripheral(B)(With the same name as peripheral A) and peripheral(A). So the central should connect again only with the peripheral(A).

Is this possible using bonding and whitelist? or there's another method to do that?

I'm using SDK 15.3

Ty in advance.

Hi

This should not be a problem at all. Once connected and bonded, the central will reconnect to the bonded device as soon as it is advertising again. We have multiple examples doing this, and I suggest you check out the BLE Heart rate collector example for central and peripheral on our Infocenter.

Best regards,

Simon

hi,

I am interested in this question

I checked  sdk15.3\examples\ble_central\ble_app_hrs_c, and in my opnion , the hrs_c example cannot demonstrate Central can reconnect the first one connected even there are another same name peripheral.

No Example has been found to demonstrate this function

I think this work may require application developer to implement through a Buf stored a first connected peripheral address ,correct?

Any help would be much appreciated!
