Changes in v3: - Discard changes to the Device Found event and notify bluetoothd only when the controller stops monitoring the device via new Device Lost event. Changes in v2: - Instead of creating a new 'Device Tracking' event, add a flag 'Device Tracked' in the existing 'Device Found' event and add a new 'Device Lost' event to indicate that the controller has stopped tracking that device. doc/mgmt-api.txt | 50 +++++++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 49 insertions(+), 1 deletion(-) diff --git a/doc/mgmt-api.txt b/doc/mgmt-api.txt index 5355fedb0..32dd8c0f2 100644 --- a/doc/mgmt-api.txt +++ b/doc/mgmt-api.txt @@ -107,7 +107,8 @@ Configuration command, Default Runtime Configuration Changed event, Get Device Flags command, Set Device Flags command, Device Flags Changed event, Read Advertisement Monitor Features command, Add Advertisement Patterns Monitor command, Remove Advertisement Monitor command, Advertisement Monitor -Added event and Advertisement Monitor Removed event. +Added event, Advertisement Monitor Removed event, Advertisement Monitor Device +Found event and Advertisement Monitor Device Lost event.
