hi , i need help!

     when i conected to the phone(bonding)，then i disconnect from the device using sd_ble_gap_disconnect(),next the device advitising again; after that the phone auto conecting to the device again 。

     but now i don’t want to reconnected by the phone ,so what should i do?

Typically what I see most do is to update the BLE address whenever they want to pair with a new host (and avoid reconnect to old host). This is typically done by call sd_ble_gap_address_get(), increment the address (e.g. byte[3]), then set the new address by calling sd_ble_gap_address_set(). Then start undirected advertisement without whitelist. The peripheral will now appear as a completely new peripheral for any host. The address can be stored in flash for later use. 

Best regards,

thank you for your replied。i changed the mac addr and it work。but the problem i encount is that i don't want to changed the addr,the reson show below:

after i disconnect from the device then i advising and don't want to auto reconnect by the phone. until i press  the connect button on the phone ,then can connect to the device again。

i try one method which i advising without whitelist but the phone also auto reconnect to the device。so what should i do?

is it work when i advising without whitelist?

What kind of peripheral is this? Are you using bonding? I do not see any easy workaround here, since this is controlled by the OS of the central device, and likely not something a peripheral can override. I think switching mac address back and forth is the best way.

Could we do that when my device connect to two phone，i disable the one of  connect handle and just make the other handle work ?

As a peripheral devices you can always disconnect a link with sd_ble_gap_disconnect().
