No API to remove particular address from whitelist

Hi,

Currently in nimble code, there is no API to remote a particular address from whitelist. The API ble_gap_wl_set https://github.com/apache/mynewt-nimble/blob/master/nimble/host/src/ble_gap.c#L2162 can be used to remove *all* entries in whitelist if the parameter white_list_count is set to 0.

Is there any specific reason to not expose such an API ( something which can invoke a HCI command for OCF BLE_HCI_OCF_LE_RMV_WHITE_LIST ) ?

Thanks,
Rahul

Start in nimble/host/src/ble_gap.c at ble_gap_wl_set and review how the existing whitelist operation handles white_list_count == 0. Trace the HCI path for BLE_HCI_OCF_LE_RMV_WHITE_LIST and determine the appropriate public API shape. Done means a caller can remove one specified address without clearing the rest of the whitelist, with behavior checked against the existing whitelist handling.
