+btsak -- Bluetooth Swiss Army Knife
+
+Commands:
+
+  Command:      help
+  Description:  Should overall command help
+  Usage:        bt <ifname> help
+
+  Command:      info
+  Description:  Show Bluetooth driver information
+  Usage:        bt <ifname> info [-h]
+
+  Command:      features
+  Description:  Show Bluetooth driver information
+  Usage:        bt <ifname> features [-h] [le]
+  Where:        le - Selects LE features vs BR/EDR features
+
+  Command:      scan
+  Description:  Bluetooth scan commands
+  Usage:        bt <ifname> scan [-h] <start [-d]|get|stop>
+  Where:        start - Starts scanning.  The -d option enables duplicate
+                  filtering.
+                get   - Shows new accumulated scan results
+                stop  - Stops scanning
+
+  Command:      advertise
+  Description:  Bluetooth advertise commands
+  Usage:        bt <ifname> advertise [-h] <start|stop>
+  Where:        start - Starts advertising
+                stop  - Stops advertising
+
+  Command:      security
+  Description:  Enable security (encryption) for a connection:
+                If device is paired, key encryption will be enabled.  If
+                the link is already encrypted with sufficiently strong
+                key this command does nothing.
+
+                If the device is not paired pairing will be initiated. If
+                the device is paired and keys are too weak but input output
+                capabilities allow for strong enough keys pairing will be
+                initiated.
+
+                This command may return error if required level of security
+                is not possible to achieve due to local or remote device
+                limitation (eg input output capabilities).
+  Usage:        bt <ifname> security [-h] <addr> public|private <level>
+  Where:        <addr>  - The 6-byte address of the connected peer
+                <level> - Security level, on of:
+
+                  low     - No encryption and no authentication
+                  medium  - Encryption and no authentication (no MITM)
+                  high    - Encryption and authentication (MITM)
+                  fips    - Authenticated LE secure connections and encryption
+
+  Command:      gatt
+  Description:  Generic Attribute (GATT) commands
+  Usage:        bt <ifname> gatt [-h] <cmd> [option [option [option...]]]
+  Where:        See "GATT Commands" below
+
+GATT Commands
+

+
+  Command:      mget
+  Description:  Get the pass/fail result of the last GATT 'exchange-mtu' command
