or the first communication equipment registers by writing a second UUID in the second SDP, wherein the second UUID is used for identifying that the first communication equipment supports the HF role; the first role registration information acquired at this time is HF role registration information; the second role registration information acquired in the subsequent registration of another role is the AG role registration information. When registering, specifically, whether the AG role or the HF role is registered first may be set in a random control manner, or according to a manner used by the previous connection, or according to a rule such as a fixed order.

In this embodiment, the first UUID and the second UUID are used to represent that the communication device supports an AG role and an HF role, respectively; in this embodiment, the first communication device characterizes the roles supported by itself by two UUIDs, respectively, and includes an AG role and an HF role.

The bluetooth searching party can be performed by the first communication device or the second communication device, that is, the first communication device can be used as a search initiator, and the second communication device can also be used as a search initiator; when the first communication device is used as a search initiator, the second communication device is used as a search receiver. In this embodiment, the AG and HF supported by the first communication device and the second communication device to establish a connection are determined, and the searcher knows the AG and HF supported by itself, and only needs to know the support of the other party by searching. In this embodiment, that is, by initiating a bluetooth search, the first bluetooth device determines the roles supported by the second bluetooth device.

In one example, initiating a bluetooth search by a first communication device, causing the first communication device to determine a role supported by a second communication device may comprise:

a first communication device initiates an SDP search request message;

and receiving an SDP search response message sent by the second communication device, wherein the SDP search response message carries characteristic values representing roles supported by the second communication device. Wherein, in the SDP searching response message, the carried feature value characterizing the role supported by the second communication device, that is, the UUID written by the second communication device during registration includes, but is not limited to, a UUID, which indicates that the bluetooth device supports one of an AG role or an HF role; or two UUIDs, indicating that the bluetooth device supports both AG and HF roles.

In some embodiments, determining the AG and HF supported by each of the first communication device and the second communication device to establish the connection may further include:

and receiving Bluetooth search initiated by the second communication equipment, so that the second communication equipment determines the role supported by the first communication equipment. This example shows that the searching party becomes the second communication device, and when the second communication device performs the search, the first communication device serves as the searched party, and correspondingly feeds back the role supported by itself to the second communication device.

In some embodiments, receiving a bluetooth search initiated by the second communication device, causing the second communication device to determine the roles supported by the first communication device may comprise:

receiving a SDP searching request message initiated by the second communication equipment;

and sending an SDP search response message to the second communication equipment, wherein the SDP search response message carries characteristic values representing the roles supported by the first communication equipment.

When the first communication device and the second communication device are connected, the connection mode can be automatic connection, connection through user control and the like, wherein the automatic connection means that the first communication device and the second communication device automatically complete Bluetooth connection after searching is completed, and Bluetooth communication can be realized between the first communication device and the second communication device through the connection after connection; the type of automatic connection may be set according to a difference between role types supported by the first communication device and the second communication device, for example, when the first communication device supports both AG and HF roles, if the second communication device supports only one of the roles, the first communication device is connected to the second communication device through the corresponding role; if the second communication device also supports two roles, the first communication device and the second communication device may randomly select a corresponding role for connection, or select a corresponding role for connection according to a preset priority. The connection is controlled by the user, which mainly aims at the situation that the first communication device and the second communication device both support two roles, and in this situation, the user can select how to connect the first communication device and the second communication device. The connection here means that a bluetooth path is established between the first communication device and the second communication device, and does not involve a data transmission process.

In some embodiments, after the registration of the audio gateway AG role and the hands-free HF role respectively for the first communication device by means of different session description protocols SDP, the method further comprises:

at least one link is occupied on RFcomm for both AG and HF roles, waiting for a subsequent connection. And the serial port linear simulation protocol (RFcomm) is suitable for serial port simulation based on the L2 CAP. HFP is implemented based on a serial port linear emulation protocol. Establishing serial port linear simulation protocol serial linear simulation protocol connection, and when sending an SABM packet, needing a service channel (server channel) registered on a service discovery protocol by a Remote end (Remote) as a parameter to distinguish different serial port linear simulation protocol connections.

In one example, establishing, by the first communication device, a connection with the second communication device through one of an AG role and an HF role may include:

when the second communication equipment only supports the AG role, the first communication equipment establishes connection with the second communication equipment through the HF role;

when the second communication equipment only supports the HF role, the first communication equipment establishes connection with the second communication equipment through the AG role;

when the second communication device supports both the AG role and the HF role, the first communication device and the second communication device establish connection through any combination of the AG role and the HF role. In one example, the first communication device establishes a connection with the second communication device via the AG role via the HF role; or the first communication device establishes connection with the second communication device through the AG role through the HF role. In other words, the connection between the two is a combination of AG and HF.

In some embodiments, after the first communication device establishes the connection with the second communication device through one of the AG role and the HF role, the method may further include:

in one example, when the first communication device maintains a connected state with the second communication device in one role, the other role can be optionally logged off; in another example, since the first bluetooth address and the second bluetooth address of the first communication device are bound to the first role registration information and the second role registration information, respectively, they may be externally presented as two communication devices respectively presenting AG role and HF role, and thus while the first communication device maintains a connection state with the second communication device in one role, the other role of the first communication device may also continue to be maintained without logging off.

It can be seen that the communication connection method provided in this embodiment may perform registration of any role of the audio gateway AG and the hands-free HF for the first communication device through the session description protocol SDP; initiating a Bluetooth search of the second communication equipment to acquire the role supporting condition of the second communication equipment; or receiving Bluetooth search initiated by the second communication equipment, and feeding back the condition of the role supported by the second communication equipment to the second communication equipment; before the first communication device and the second communication device are matched, the first communication device is registered with the other role in the AG and the HF through the SDP; matching roles between the first communication device and the second communication device; and establishing connection with the second communication equipment in the matched role. Therefore, when the Bluetooth function of the communication equipment is started, the AG role and the HF role can be successively registered for the same communication equipment, so that the application range of the communication equipment is expanded, and the user experience is improved.

In this embodiment, the process of acquiring the first bluetooth address is included before the first role registration information is bound with the first bluetooth address, and correspondingly, the process of acquiring the second bluetooth address is included before the second role registration information is bound with the second bluetooth address. And it should be understood that, in this embodiment, the first communication device may perform registration of the AG role and the HF role through the protocol stack, and perform acquisition of first role registration information (hereinafter, referred to as the AG role) and second role registration information. The protocol stack can be various Bluetooth protocol stacks, and can be flexibly selected according to requirements.

It should be understood that, in the embodiment, when performing AG role and HF role registration, the AG role registration may be performed first, and after the AG role registration is completed, the HF role registration may be performed again; or the HF role registration is carried out first, and the AG role registration is carried out after the HF role registration is finished.

In this embodiment, the first bluetooth address and the second bluetooth address are different bluetooth addresses. And the specific format of the bluetooth address in this embodiment can also be flexibly set according to the requirement.

In this embodiment, the obtaining manner of the first bluetooth address and the second bluetooth address can be flexibly set. For ease of understanding, the present embodiment will be described below by taking several bluetooth address acquisition manners as examples.

In one example, for the first bluetooth address, a solidified bluetooth address can be written in the first communication device in advance, and the first bluetooth address can be stored in a bluetooth address storage file in the first communication device; for example, one storage method may be writing the data into a predetermined bin file in a binary manner for storage. When the role is registered, the first bluetooth address can be read from the bin file. Of course, it should be understood that the first bluetooth address in this embodiment may also be dynamically generated by a preset rule when needed, and is not limited to the above-described exemplary obtaining manner.

In one example, the second bluetooth address may be obtained by, but not limited to, any one of the following three obtaining manners:

the first method is as follows: fig. 5 shows a process of acquiring the second bluetooth address, which includes:

s501: before receiving second registration information sent by a protocol stack, calling a preset Bluetooth address algorithm to generate a second Bluetooth address, and storing the second Bluetooth address in a preset Bluetooth address storage file; and the second bluetooth address can be stored in a different bluetooth address storage file with the first bluetooth address, and can also be stored in the same bluetooth address storage file. For example, the second bluetooth address may be stored in a bin file stored in the first bluetooth address.

S502: and when the Bluetooth module of the first communication device is started, reading the second Bluetooth address from the Bluetooth address storage file.

The second method comprises the following steps: and when needed, directly calling a preset Bluetooth address algorithm to generate a second Bluetooth address. This way, the second bluetooth address can be dynamically generated in real time when needed.

The third method comprises the following steps: fig. 6 shows a process of acquiring the second bluetooth address, which includes:

s601: and when the Bluetooth module of the first communication device is started, reading the second Bluetooth address from a preset Bluetooth address storage file.

S602: judging whether the second Bluetooth address is successfully read, if so, turning to S603; otherwise, go to S604.

S603: the second bluetooth address acquisition is finished.

S604: and calling a preset Bluetooth address algorithm to generate a second Bluetooth address, and storing the generated second Bluetooth address in a Bluetooth address storage file.

It should be understood that, in this embodiment, the first bluetooth address and the second bluetooth address may be obtained simultaneously, or the first bluetooth address may be obtained first and then the second bluetooth address is obtained, or the second bluetooth address is obtained first and then the first bluetooth address is obtained, which may be flexibly obtained according to a specific application scenario.

Through binding the AG role and the HF role registered by the first communication equipment with two different Bluetooth addresses of the first communication equipment respectively, the first communication equipment is enabled to be externally presented as two independent first communication equipment, and then the first communication equipment can simultaneously support the AG role and the HF role, and can establish AG connection or HF connection with other first communication equipment according to requirements, even establish AG connection and HF connection simultaneously, so that the application of Bluetooth communication is more flexible, the adaptability is better, the Bluetooth communication system can be better suitable for various Bluetooth communication application scenes, and the satisfaction degree of user experience is improved.

In an example in this embodiment, the first bluetooth address is a bluetooth address pre-written in the first communication device and stored in a bluetooth address storage file in the first communication device; in this example, invoking the preset bluetooth address algorithm to generate the second bluetooth address may include:

and acquiring a first Bluetooth address, and randomly converting the value in the low-end area of the address in the first Bluetooth address to obtain a second Bluetooth address. The random switching manner in this embodiment can be flexibly adopted as long as it can be ensured that the obtained second bluetooth address is different from the first bluetooth address. In order to further improve the reliability, after the second bluetooth address is generated, whether the second bluetooth address is the same as the first bluetooth address or not can be judged, if so, the value in the area of the lower end of the address in the first bluetooth address is randomly transformed again to obtain the second bluetooth address, and then the second bluetooth address is compared with the first bluetooth address until the second bluetooth address is different from the first bluetooth address.

In this example, in order to further improve reliability and accuracy, it may further include detecting whether the first bluetooth address is updated, and if so, obtaining the updated first bluetooth address, and randomly transforming a value in a low-end region of an address in the updated first bluetooth address to obtain a new second bluetooth address.

Therefore, the HF role and the AG role registered by the first communication equipment can be respectively bound with a mutually independent Bluetooth address, so that the first communication equipment is externally presented as two independent first communication equipment, the AG role and the HF role can be simultaneously supported by the first communication equipment, and AG connection and/or HF connection can be established with other first communication equipment according to requirements, so that Bluetooth communication application is more flexible, adaptability is better, the method and the device can be better suitable for various Bluetooth communication application scenes, and the satisfaction degree of user experience is improved.

Second embodiment

For convenience of understanding, the present embodiment is described with reference to a specific application scenario as an example on the basis of the foregoing embodiment.

In this embodiment, the communication system includes a first communication device and a second communication device, wherein the registration procedure shown in the above embodiments can be adopted for at least one communication device. For ease of understanding, the following description will be given taking a registration process of the first communication device as an example.

In this embodiment, when the first communication device writes a bluetooth address, in addition to the default configured first bluetooth address, a bluetooth address algorithm may be invoked to generate a new bluetooth address (i.e., a MAC address) as a second bluetooth address, and the new bluetooth address may be written into the bin file; and optionally, the first bluetooth address and the second bluetooth address may be written into the same bin file.

Then, when the bluetooth module of the first communication device is started, the firmware of the bluetooth module of the first communication device may directly read the first bluetooth address and the second bluetooth address from the bin file and write the first bluetooth address and the second bluetooth address into the storage space of the bluetooth module. When the first communication device performs bluetooth role registration through the SDP, the AG role registration may be performed through the bluetooth protocol stack, and then the AG role registration information is transferred to the firmware of the bluetooth module of the first communication device, and the firmware may bind the AG role registration information with the first bluetooth address (or with the second bluetooth address, of course); the first communication device may then register the HF role via the bluetooth protocol stack and then pass the HF role registration information to the firmware of the bluetooth module of the first communication device, which may bind the HF role registration information with the second bluetooth address (and of course also with the first bluetooth address). In this way, the AG function and the HF function of the first communication device are implemented on the first bluetooth address and the second bluetooth address, respectively, which appear to the third-party device as two different first communication devices, so that the first bluetooth address can always be present as a master device and the second bluetooth address can always be present as a slave device, and the first communication device can flexibly establish at least one of an AG connection and an HF connection with the third-party first communication device.

For ease of understanding, the present embodiment is illustrated below with an exemplary bluetooth protocol stack. Referring to fig. 7, the bluetooth protocol stack in this embodiment includes, but is not limited to, the following parts:

a PHY layer (Physical layer) for specifying a radio frequency band, a modulation/demodulation method, and a method used for BLE. The PHY layer may determine the power consumption, sensitivity, and selectivity of the entire BLE chip.

The LL Layer (Link Layer) is a core of the entire BLE protocol stack, and may implement, but is not limited to, selecting which radio frequency channel to communicate, how to identify an air data packet, specifically, at which time point to send out the data packet, how to ensure integrity of data, how to receive ACK, how to retransmit, how to manage and control a Link, and the like. The LL layer is responsible for sending data out or receiving data back, and what kind of analysis is done on the data is handed over to the GAP or ATT above.

HCI (Host controller interface), which is optional, in an example, the HCI may be used in a case where 2 chips implement a BLE protocol stack, and is used to specify a communication protocol and a communication command between the two.

GAP layer (Generic access profile, generic access specification). GAP is one of two ways to parse how LL layer payload (valid packet). GAPs simply make some specifications and definitions of LL payload, which GAPs can use to broadcast, scan, initiate connections, and so on.

L2CAP layer (logical link control and adaptation protocol), L2CAP performs a simple encapsulation on LL, LL only cares about the transmitted data itself, L2CAP shall distinguish whether it is an encrypted channel or a normal channel, and at the same time, it shall manage the connection interval.

SMP (Secure manager protocol), which is a work to be considered by SMP, is used to manage encryption and security of BLE connection, and how to ensure the security of connection without affecting user experience.

ATT (Attribute protocol), the ATT layer is used to define user commands and data of command operations, such as reading certain data or writing certain data.

GATT (Generic attribute profile), which is used to specify the data content in an attribute and apply the concept of group to classify and manage the attribute.

This embodiment also provides an example of the structure of bluetooth address, in this example, the bluetooth device address (BD _ ADDR) is a unique identifier of 48 bits, and is composed of LAP (24-bit address low end part), UAP (8-bit address high end part) and NAP (16-bit meaningless address part), and its format is shown in fig. 8:

NAP and UAP are unique identification codes of manufacturers of Bluetooth devices, and are distributed to the manufacturers by SIG; LAP is self-distributed by the manufacturer. Wherein, bit40 is a multicast address flag bit, and the value thereof is 0: unicast, with a value of 1: multicast; bit41 is an address type flag bit, and its value is 0: a univeral addr having a value of 1: local addr.

On the basis of the above example, the present embodiment will be described below with reference to the registration process shown in fig. 9 as an example. Please refer to fig. 9, which includes:

s901: the bluetooth module of the first communication device is started.

S902: the bluetooth module performs registration of the AG role and the HF role (may register the AG role first and then the HF role, or may register the HF role first and then the AG role).

S903: loading the AG function and the HF function through a Bluetooth protocol stack.

S904: and transmitting the AG role registration information and the HF role registration information to the firmware through a Bluetooth protocol stack.
