Ignore whitelist when scanning beacons

[sboudaud]

Hi,

In these conditions "custom device connected+bonded and whitelist enabled", when the device scan for beacons it see only the smartphone bonded to the device (don't see the beacons simulated by the smartphone)

is it possible to disable whitelist just for the scan?

the scan is configured as below:

        .extended    = 0,
        .active          = passive_scan,
        .filter_policy = BLE_GAP_SCAN_FP_ACCEPT_ALL,
        .interval        = MSEC_TO_UNITS(130, UNIT_0_625_MS),
        .window        = MSEC_TO_UNITS(120, UNIT_0_625_MS),
        .timeout        = 0, /* none timeout by default  - set by application */

SDK16, SD7.0.1, nrf52832, custom device, custom application

Hello Joakim,

The ticket https://devzone.nordicsemi.com/f/nordic-q-a/39922/about-whitelist-scan-filtering/154862#154862 is for SDK12 but I use the SDK16 where the structure ble_gap_scan_params_t is not the same.

I don't want to use "nrf_ble_scan_params_set(&m_scan, NULL);" because with NULL I will lose my configuration?

If I understood something wrong please tell me?

Thanks

Are you using the advertising module?

ble_advertising_restart_without_whitelist()

You can see how this is used in the ble_app_hids_keyboard example in the SDK.

Hello Joakim,

My problem is not in advertisement module but in scanning module.

What I want is that my device:

1- advertise with whitelist, the only central that could connect is the bonded one

2- When connected to a central it (the device) could make a scan for beacons (geolocation feature)

My problem is that when connected to a central, my device make a scan and it see only the connected central address.

My request is how to disable whitelist only for scanner module?

Thanks

Ok, if you look at the ble_app_hrs_c example in the SDK, this exact usecase is demonstrated.

Seetting the m_whitelist_disabled flag to true will temporarily disable the whitelist.

Calling the function whitelist_disable in the example will set m_whitelist_disabled to true, stop scanning and start scanning again without whitelist.
