Filtering based on 128 bit uuid

[erdemsimsek]

Hello,

I am developing application based on nRF52833 DK. Basically, my application scans all iBeacon messages (ADV_NONCONNETABLE) and transmit to computer.

I would like to make filter based UUIDs inside iBeacon packet format. The UUID is 128 bit lenght. Is there any filters in SDK that I can use?

I saw this function nrf_ble_scan_filter_set. However, this function use only 16 bit UUID.

nrf_ble_scan_filter_set call this function inside 

case SCAN_UUID_FILTER:
{
ble_uuid_t * p_uuid = (ble_uuid_t *)p_data;
return nrf_ble_scan_uuid_filter_add(p_scan_ctx, p_uuid);
}

ble_uuid_t structure holds only 16 bit uuid. Is there any way to filter iBeacon messages based on 128 bit UUID?

Thanks

Hi

You can, for example, use a whitelist that holds the UUIDs you want to scan in order to filter these beacons. You should also be able to add scan filters to single UUIDs.

Best regards,

Of course, it is possible. Does Nordic provide API for that purpose?
