/** \file
* This _dbt_scanner10_ C++ scanner ::BTRole::Master example uses the Direct-BT fully event driven workflow
* and adds multithreading, i.e. one thread processes each found device found
* as notified via the event listener.
*
* _dbt_scanner10_ represents the recommended utilization of Direct-BT.
*
* ### dbt_scanner10 Invocation Examples:
* Using `scripts/run-dbt_scanner10.sh` from `dist` directory:
* * Scan and read all devices (using default auto-sec w/ keyboard iocap)
* ~~~
* ../scripts/run-dbt_scanner10.sh
* ~~~
*
* * Read device C0:26:DA:01:DA:B1 (using default auto-sec w/ keyboard iocap)
* ~~~
* ../scripts/run-dbt_scanner10.sh -dev C0:26:DA:01:DA:B1
* ~~~
*
* * Read device C0:26:DA:01:DA:B1 (using default auto-sec w/ keyboard iocap) from adapter 01:02:03:04:05:06
* ~~~
* ../scripts/run-dbt_scanner10.sh -adapter adapter 01:02:03:04:05:06 -dev C0:26:DA:01:DA:B1
* ~~~
*
* * Read device C0:26:DA:01:DA:B1 (enforcing no security)
* ~~~
* ../scripts/run-dbt_scanner10.sh -dev C0:26:DA:01:DA:B1 -seclevel C0:26:DA:01:DA:B1 1
* ~~~
*
* * Read any device containing C0:26:DA (enforcing no security)
* ~~~
* ../scripts/run-dbt_scanner10.sh -dev C0:26:DA -seclevel C0:26:DA 1
* ~~~
*
* * Read any device containing name `TAIDOC` (enforcing no security)
* ~~~
* ../scripts/run-dbt_scanner10.sh -dev 'TAIDOC' -seclevel 'TAIDOC' 1
* ~~~
*
* * Read device C0:26:DA:01:DA:B1, basic debug flags enabled (using default auto-sec w/ keyboard iocap)
* ~~~
* ../scripts/run-dbt_scanner10.sh -dev C0:26:DA:01:DA:B1 -dbt_debug true
* ~~~
*
* * Read device C0:26:DA:01:DA:B1, all debug flags enabled (using default auto-sec w/ keyboard iocap)
* ~~~
* ../scripts/run-dbt_scanner10.sh -dev C0:26:DA:01:DA:B1 -dbt_debug adapter.event,gatt.data,hci.event,hci.scan_ad_eir,mgmt.event
* ~~~
*
* ## Special Actions
* * To do a BT adapter removal/add via software, assuming the device is '1-4' (Bus 1.Port 4):
* ~~~
* echo '1-4' > /sys/bus/usb/drivers/usb/unbind
* echo '1-4' > /sys/bus/usb/drivers/usb/bind
* ~~~
