The tool works with Bluetooth Classic (BR/EDR) and Bluetooth Low Energy (LE) controllers. +The tool is menu driven but can be automated from the command line.

The submenu commands can be found at their own pages which are listed below. + Submenu items can either be accessed with the menu option i.e. 'menu advertise' or directly from the main menu with dot notation i.e. 'advertise.tx-power on' + + +MAIN MENU COMMANDS +================== + +menu advertise +-------------- +Advertise Options Submenu + +:Usage: **# menu advertise** + +menu monitor +------------ +Advertisement Monitor Options Submenu + +:Usage: **# menu monitor** + +menu scan +--------- +Scan Options Submenu + +:Usage: **# menu scan** + +menu gatt +--------- +Generic Attribute Submenu + +:Usage: **# menu gatt** + +menu admin +---------- +Admin Policy Submenu + +:Usage: **# menu admin** + +menu player +----------- +Media Player Submenu + +:Usage: **# menu player** + +menu endpoint +------------- +Media Endpoint Submenu + +:Usage: **# menu endpoint** + +menu transport +-------------- +Media Transport Submenu + +:Usage: **# menu transport** + +list +---- +List available controllers + +:Usage: **# list** + +show +---- +Controller information + +:Usage: **# show [ctrl]** + +select +------ +Select default controller + +:Usage: **# select <ctrl>** + +devices +------- +List available devices, with an optional property as the filter + +:Usage: **# devices [Paired/Bonded/Trusted/Connected]** + +system-alias +------------ +Set controller alias + +:Usage: **# system-alias <name>** + +reset-alias +----------- +Reset controller alias + +:Usage: **# reset-alias** + +power +----- +Set controller power +When the controller is powered off, the USB port the controller is attached to is put into a suspend state. When the controller is powered on the port is taken out of a suspend state and the controller is power cycled. Any firmware will be reloaded at this time. + +:Usage: **# power <on/off>** + +advertise +--------- +Enable/disable advertising with given type +Will start advertising. If you exit the program advertising will be disabled. When advertising the controller should advertise with random address but may use its public address if it does not support the feature (address of the device) +A device can advertise if it initiated the connection to another advertising device. +When advertising the controller will always advertise with the connectable option. + +:Usage: **# advertise <on/off/type>** + +set-alias +--------- +Set device alias + +:Usage: **# set-alias <alias>** + +scan +---- +Scan for devices + For LE, scanning is an important requirement before connecting or pairing. The purpose of scanning is to find devices + that are advertising with their discoverable flag set (either limited or general). Once you have found the address + then you can connect or pair. Note the following when scanning: + + - When scanning the controller will use a random address that is not resolvable. A new random address is created every time scan on is used. + - When turning on scanning the device will start receiving advertising reports of what devices are advertising. + - The filtering of duplicate advertising reports is enabled. + - The scan interval and scan window are fixed at 11.250 msec. + - You do get advertising reports from nondiscoverable devices. + - Scan reports have a finite time duration and will expire. If they expire you will need to scan again before connecting or pairing. + +:Usage: **# scan <on/off/bredr/le>** + +pair +---- +Pair with device +This will pair with a device and then trust and connect to it. If the device is already paired this will first remove the pairing. +Pairing provides authentication or encryption. The command can either be used while the controller is in the connected or not connected state. +If the controller is already connected then the pair command can be used without an arguments. If the controller is not connected, the pair +command can be given the address of a device with an active scan report and it will initiate the connection before pairing. +Before pairing the agent must be selected to choose the authentication mechanism. + +:Usage: **# pair <dev>** + +pairable +-------- +Set controller pairable mode +This enables/disables pairing. If pairing is disabled then the controller will not accept any pairing requests. + +:Usage: **# pairable <on/off>** + +discoverable +------------ +Set discoverable mode +This enables/disables discoverable mode. If discoverable is disabled then the controller will not respond to any scan requests. +In LE if discoverable if off the controller will just passively scan and not make scan requests to advertising devices. If on it will make the advertising requests. +It will use a random address if supported by the controller.

If the device is not paired this will first pair and then trust and connect to it. +To connect with a device the controller must have an active scan report of the device it wants to connect to. The advertising report can be obtained either by using the scan command +otherwise the connect command will issue a HCI_LE_Set_Extended_Scan_Enable to find the device. If no advertising report is received before the timeout a le-connection-abort-by-local +error will be issued.
