However, the bluetooth specification is not strictly followed by the car equipment manufacturers on the market today, and many times the writing of Device of Class is inaccurate, so identifying the Device type by Device of Class lacks accuracy in many scenarios. Therefore, the present application provides a method for determining a device type, and please refer to the following embodiments for detailed steps of the method.

The bluetooth communication system includes a first device 120 and a second device 140. Wherein the first device 120 and the second device 140 both have bluetooth functionality.
For example, in the case that the bluetooth function of the first device 120 is turned on and the bluetooth function of the second device 140 is turned on, the first device 120 searches for bluetooth devices within a distance-allowed range, and displays a list of the searched bluetooth devices on the display of the first device 120, wherein if the second device 140 is within the distance-allowed range, the list includes a selection control of the second device 140, and the selection control includes a device name of the second device 140; the first device 120 receives the triggered selection operation on the selection control of the second device 140, and establishes the bluetooth connection between the first device 120 and the second device 140.
Illustratively, a bluetooth automatic connection function is provided between the first device 120 and the second device 140; in the case where the bluetooth function of the first device 120 is turned on and the bluetooth function of the second device 140 is turned on, the first device 120 detects that the second device 140 is located within the distance allowable range, and the first device 120 automatically establishes a bluetooth connection with the second device 140.
The above distance allowable range refers to a distance range that allows bluetooth connection to be established between two bluetooth devices. The Bluetooth connection can be established between two Bluetooth devices within the distance allowable range, and the Bluetooth connection cannot be established between two Bluetooth devices outside the distance allowable range.

Illustratively, an application that supports a positioning function of a vehicle parking position is installed and executed in the first device 120. When the positioning function of the vehicle stopping position is used on the first device 120, a bluetooth connection is established between the first device 120 and the second device 140, protocol configuration information and Input Output (IO) configuration information of a protocol supported by the second device 140 are acquired through the bluetooth connection, whether the second device 140 is a vehicle-mounted device is determined based on the protocol configuration information and the IO configuration information, and if yes, the vehicle stopping position is positioned.

For example, when the bluetooth functions of the first device and the second device are both turned on, the first device receives a search operation for the bluetooth device, which is triggered by the input device, and searches for the second device within a distance allowable range; and receiving a connection operation between the first device and the second device, which is triggered by the input device, such as a click operation, a double click operation or a sliding operation on a selection control corresponding to the second device, and establishing a bluetooth connection between the first device and the second device.
For example, in a case that the bluetooth functions of the first device and the second device are both turned on and an automatic connection function is provided between the first device and the second device, the first device automatically searches for the second device within the allowable distance range and automatically establishes bluetooth connection with the second device.
For example, in a case where the bluetooth function of the first device is not turned on, first, the first device receives a bluetooth turn-on operation on the input device, and starts the bluetooth function of the first device. Illustratively, the input device includes at least one of a touch screen and a physical key.

For example, target configuration information exists in the second device under the target function, and the first device requests the target configuration information from the second device; and under the condition that the second equipment returns the target configuration information to the first equipment, the first equipment determines that the protocol support capability supports the target function. Illustratively, the target configuration information may be at least one protocol configuration information of at least one protocol.

Illustratively, the first device determines whether the protocol configuration information indicates that the second device supports MAP; in case the protocol configuration information indicates that the second device supports the MAP, it is determined that the second device is the in-vehicle device.
Or, the first device judges whether the protocol configuration information supports a Browsing function in the AVRCP; and in the case that the protocol configuration information indicates that the second device supports the Browsing function in the AVRCP, determining that the second device is the vehicle-mounted device.

For example, the first device determines, through the protocol configuration information, whether the second device supports a Browsing function in the MAP or AVRCP; in case the protocol configuration information indicates that the second device supports the Browsing function in the MAP or AVRCP, step 460 is performed; in case the protocol configuration information indicates that the second device does not support the Browsing function in the MAP or AVRCP, step 440 is performed.
Illustratively, the first device obtains the configuration information of the MAP from the first designated flag bit, and executes step 460; or, the first device obtains the configuration information of the Browsing function in the AVRCP from the first designated flag bit, and executes step 460.
The device type is judged through the target function, most vehicle-mounted devices can be efficiently screened out from various types of devices, and if the condition that the protocol support capability supports the target function is met, subsequent judging steps are not needed; if the protocol support capability does not support the target function, step 440 is executed to continue the determination of the device type.
Step 440: and judging whether the second equipment supports the screen display function or not through the IO configuration information.
The first device executes step 450 if the IO configuration information indicates that the second device supports the screen display function; in case the IO configuration information indicates that the second device does not support the screen display function, step 470 is performed.
Illustratively, the first device obtains the configuration information of the screen display function from the second designated flag, and executes step 450.
Because equipment such as bluetooth headset, bluetooth speaker carries on the display screen very seldom, and the mobile unit must carry on the display screen, consequently can read the input/output stream support characteristic of second equipment for get rid of a great deal of common audio equipment.
Step 450: and judging whether the second device supports HFP or not through the protocol configuration information.
The first device performs step 460 if the protocol configuration information indicates that the second device supports HFP; in case the protocol configuration information indicates that the second device does not support HFP, step 470 is performed.
Illustratively, the transmission frame includes a third designated flag, and the first device obtains the configuration information of HFP from the third designated flag, and executes step 460. Illustratively, the flag bit of the HFP configuration information is different from the flag bit of the target function configuration information.
The determination of whether the protocol support capability of the second device supports HFP is mainly used to exclude devices with bluetooth function, such as a television and a tablet, which cannot be screened out in step 440.
Step 460: it is determined that the second device is an in-vehicle device.
The first device determines that the second device is an in-vehicle device.
Step 470: it is determined that the second device is not an in-vehicle device.
The first device determines that the second device is not an in-vehicle device.
