i add  16 addr in the whitelist_addrs,then use sd_ble_gap_whitelist_set(whitelist_addrs,16),but it failed。return  0000000C，it meanning The given whitelist size is invalid (zero or too large); this can only return when  pp_wl_addrs is not NULL。then i use sd_ble_gap_whitelist_set(whitelist_addrs,8),it ok.so then  Maximum amount   scan whitelist is 8?i use sd_ble_gap_whitelist_set(whitelist_addrs,9),  it failed too.

my english is not good, thanks

Hi, 

You could find the define BLE_GAP_WHITELIST_ADDR_MAX_COUNT (8) in the ble_gap.h. Whitelisting is handled in HW, and the maximum number of 8 is given by the RADIO peripheral (it has 8 DAB/DAP registers). It cannot be expanded.

Thank you. i have changed  BLE_GAP_WHITELIST_ADDR_MAX_COUNT  to  more than 8. it should be not working because of the RADIO peripheral? Thank you very much.

Hi,

Yes. That is the hardware limitation.
