How does the advertisement filter policy work?

[balaji]

Hi,

How does the advertisement filter policy work?

I tried both BLE_GAP_ADV_FP_FILTER_SCANREQ and BLE_GAP_ADV_FP_FILTER_BOTH, but this doesn't restrict other devices (not in white-list) to find it, while scanning (but avoids connection request).

How can i restrict my device advertisement so that devices in white-list only can see my device is advertising?

Thanks for the Reply Pal,

How can i set BLE_GAP_DISC_MODE_NOT_DISCOVERABLE advertisement type? I dont see any example application which implements it.

As per the bluetooth core document, does setting non-connectable undirected advertisement mode enables non-discoverable advertisement?

What is 4.1 privacy? Can i get the reference document on this?

How can i set the own address type?

Sorry that i couldn't able to get your suggestion, so please make it clear on next post.

Regards, Balaji

Hi balaji, I updated my original post to include more date, setting the device address can be set with sd_ble_gap_address_set https://devzone.nordicsemi.com/documentation/nrf51/5.2.0/html/a00845.html#ga073bbb0a6e68fe0a0ef8bb59d829c986

As for the privacy, that is using a IRK to encrypt part of a random number in the address, making a hash, that you put as the other half of the address. This way other devices that have your IRK can identify the address as yours. GAP 10.7 in the Bluetooth Core spesification.
