Bluetooth: Enhanced Connection Complete event belongs to LL Privacy

2020-04-16T09:43:03Z

The Enhanced Connection Complete event is use in conjunction with LL Privacy and not Extended Advertising. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Enable LE Enhanced Connection Complete event.

2020-04-15T13:51:05Z

In case LL Privacy is supported by the controller, it is also a good idea to use the LE Enhanced Connection Complete event for getting all information about the new connection and its addresses. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Add support for Read Local Simple Pairing Options

2020-04-05T11:53:11Z

With the Read Local Simple Pairing Options command it is possible to retrieve the support for max encryption key size supported by the controller and also if the controller correctly verifies the ECDH public key during pairing.

Bluetooth: Add framework for Microsoft vendor extension

2020-04-05T11:53:05Z

Micrsoft defined a set for HCI vendor extensions. Check the following link for details: https://docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/microsoft-defined-bluetooth-hci-commands-and-events This provides the basic framework to enable the extension and read its supported features. Drivers still have to declare support for this extension before it can be utilized by the host stack. Signed-off-by: Miao-chen Chou Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Prioritize SCO traffic

2020-04-03T06:47:09Z

When scheduling TX packets, send all SCO/eSCO packets first, check for pending SCO/eSCO packets after every ACL/LE packet and send them if any are pending. This is done to make sure that we can meet SCO deadlines on slow interfaces like UART. If we were to queue up multiple ACL packets without checking for a SCO packet, we might miss the SCO timing. For example: The time it takes to send a maximum size ACL packet (1024 bytes): t = 10/8 * 1024 bytes * 8 bits/byte * 1 packet / baudrate where 10/8 is uart overhead due to start/stop bits per byte Replace t = 3.75ms (SCO deadline), which gives us a baudrate of 2730666. At a baudrate of 3000000, if we didn't check for SCO packets within 1024 bytes, we would miss the 3.75ms timing window. Signed-off-by: Abhishek Pandit-Subedi Signed-off-by: Marcel Holtmann

Bluetooth: Restore running state if suspend fails

2020-03-23T17:48:50Z

If Bluetooth fails to enter the suspended state correctly, restore the state to running (re-enabling scans). PM_POST_SUSPEND is only sent to notifiers that successfully return from PM_PREPARE_SUSPEND notification so we should recover gracefully if it fails.

Bluetooth: Handle BR/EDR devices during suspend

2020-03-11T17:01:47Z

To handle BR/EDR devices, we first disable page scan and disconnect all connected devices. Once that is complete, we add event filters (for devices that can wake the system) and re-enable page scan. Signed-off-by: Abhishek Pandit-Subedi Signed-off-by: Marcel Holtmann

Bluetooth: Handle PM_SUSPEND_PREPARE and PM_POST_SUSPEND

2020-03-11T17:00:48Z

Register for PM_SUSPEND_PREPARE and PM_POST_SUSPEND to make sure the Bluetooth controller is prepared correctly for suspend/resume. Implement the registration, scheduling and task handling portions only in this patch. Signed-off-by: Abhishek Pandit-Subedi Signed-off-by: Marcel Holtmann

Bluetooth: fix off by one in err_data_reporting cmd masks.

2020-03-11T14:25:15Z

This change fixes the off by one error in the erroneous command bit masks which can lead to the erroneous data commands being sent to a controller that doesn't support them. Signed-off-by: Alain Michaud Signed-off-by: Marcel Holtmann

Bluetooth: Enable erroneous data reporting if WBS is supported

2020-03-08T07:50:42Z

This change introduces a wide band speech setting which allows higher level clients to query the local controller support for wide band speech as well as set the setting state when the radio is powered off. Internally, this setting controls if erroneous data reporting is enabled on the controller. Signed-off-by: Alain Michaud Signed-off-by: Marcel Holtmann
