Function requirements 

IMPORTANT In order to be able to operate a Bluetooth-compatible mobile phone authorized at the COMAND operating, display and controller unit in the vehicle, the mobile phone must support the handsfree profile (HFP) 1.0 or 1.5.

General 

The COMAND operating, display and controller unit supports the standard Bluetooth network technology for easy and rapid integration of mobile phones in the vehicle. Bluetooth is a worldwide open standard for connecting Bluetooth devices (e.g. mobile phones) wirelessly and is based on radio technology in the 2.4 GHz range. One advantage of Bluetooth, next to the wide availability of Bluetooth devices, is the uncomplicated and spontaneous connection of Bluetooth devices to a Bluetooth network (ad-hoc network). The extremely high data security (128-bit encoding) and the relatively limited radius (approx. 10 m) of such a Bluetooth network is what makes the use of Bluetooth in the vehicle interesting.

The COMAND operating, display and controller unit can integrate mobile phones of the newest generation into the vehicle hierarchy using the Bluetooth interface mobile phone and the Bluetooth antenna (A2/91).

If no mobile phone is authorized yet at the COMAND operating, display and controller unit via Bluetooth, a search for Bluetooth-compatible devices can be performed using the COMAND operating, display and controller unit. If Bluetooth devices were found, the user is notified of all the Bluetooth devices listed in terms of trustworthiness ("trust" or "untrust"). The user can then authorize available Bluetooth devices (log on), interrupt connections to trustworthy Bluetooth devices or deauthorize Bluetooth devices.

The mobile phone system includes the following processes:

Switching on and off characteristics 

A mobile phone operated with Bluetooth can be switched on and off only with the buttons on the mobile phone itself. The switch-on signal is processed internally in the mobile phone. The lock code inquiry is only shown on the display of the mobile phone, if configured on the mobile phone and if the mobile phone transmits this status. The lock code can only be entered using the buttons on the mobile phone. The reception status is received by the mobile phone's antenna.

The display of the lock-code and the reception status as well as the signals of the mobile phone buttons are processed internally in the mobile phone.

The switch-off signal via the mobile phone button is processed internally in the mobile phone. If the rechargeable battery of the mobile phone is empty, the mobile phone is also switched off. This process also runs internally in the mobile phone.

Function requirements for establishing and terminating a call 

IMPORTANT With a mobile phone operated with Bluetooth, read access to the telephone book in the mobile phone is possible when the mobile phone supports the Bluetooth Profile Phonebook Access Profile (PBAP).
