Test performed: - verified by logs that Monitor Device is received from the controller and sent to the bluetoothd when the controller starts/stops monitoring a bluetooth device. --- Changes in v3: - Fix indentation of the adv_monitor_device_lost_callback() name and it's arguments. Changes in v2: - Update function name adv_monitor_tracking_callback() to adv_monitor_device_lost_callback() as it will receive only Device Lost event. src/adv_monitor.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) diff --git a/src/adv_monitor.c b/src/adv_monitor.c index 715ac5904..385ab26e6 100644 --- a/src/adv_monitor.c +++ b/src/adv_monitor.c @@ -1531,6 +1531,27 @@ static void adv_monitor_removed_callback(uint16_t index, uint16_t length, ev->monitor_handle); } +/* Processes Adv Monitor tracking event from kernel */ +static void adv_monitor_device_lost_callback(uint16_t index, uint16_t length, + const void *param, void *user_data) +{ + struct btd_adv_monitor_manager *manager = user_data; + const struct mgmt_ev_adv_monitor_device_lost *ev = param; + uint16_t handle = le16_to_cpu(ev->monitor_handle); + const uint16_t adapter_id = manager->adapter_id; + char addr[18]; + + if (length < sizeof(*ev)) { + btd_error(adapter_id, + "Wrong size of Adv Monitor Device Lost event"); + return; + } + + ba2str(&ev->addr.bdaddr, addr); + DBG("Adv monitor with handle 0x%04x stopped tracking the device %s", + handle, addr); +} + /* Allocates a manager object */ static struct btd_adv_monitor_manager *manager_new( struct btd_adapter *adapter, @@ -1555,6 +1576,10 @@ static struct btd_adv_monitor_manager *manager_new( manager->adapter_id, adv_monitor_removed_callback, manager, NULL); + mgmt_register(manager->mgmt, MGMT_EV_ADV_MONITOR_DEVICE_LOST, + manager->adapter_id, adv_monitor_device_lost_callback, + manager, NULL); + return manager; }
