[PATCH v7 09/20] Bluetooth: mgmt: multi adv for enable_advertising()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Previously enable_advertising() would rely on
get_adv_instance_scan_rsp_len() which checked for a hard coded instance
identifier. This is being changed to check for the current advertising
instance's scan response length instead. The function is renamed
accordingly.
