Fig. 1 is a simplified functional block diagram of a bluetooth communication system 100 according to an embodiment of the present invention. The bluetooth communication system 100 includes a transmitting-side bluetooth device 110, a receiving-side bluetooth device 120, and a triggering device 130. Both the transmitting-side bluetooth device 110 and the receiving-side bluetooth device 120 may be stand-alone devices or may be local circuits integrated in other devices.
In the embodiment of fig. 1, the tx bluetooth device 110 includes a tx bluetooth transceiving circuit 111, a packet generating circuit 113, a tx control circuit 115, and a receiving interface 117. The receiving-end bluetooth device 120 includes a receiving-end bluetooth transceiving circuit 121, a packet parsing circuit 123, and a receiving-end control circuit 125.
In the transmitting bluetooth device 110, the packet generating circuit 113 is coupled to the transmitting bluetooth transceiving circuit 111.

The tx control circuit 115 is further configured to control the tx bluetooth transceiving circuit 111 to transmit the one or more packets when the tx bluetooth device 110 operates in a tx predetermined operation mode. The receiving interface 117 is coupled to the transmit control circuit 115 and configured to receive a user trigger signal (user trigger signal) generated by the trigger device 130.
The aforementioned "automatic pairing request" refers to various indication information or instructions for another wireless device to actively perform a bluetooth pairing procedure with the transmitting bluetooth device 110.
In practice, different functional blocks in the transmitting-side bluetooth device 110 can be implemented by different circuits respectively, or can be integrated into a single circuit chip. In addition, the transmitting-end bluetooth transceiver circuit 111 may also be coupled to an additional antenna device (not shown), if necessary.
In the receiving bluetooth device 120, the receiving bluetooth transceiving circuit 121 is configured to receive one or more target packets from the transmitting bluetooth device 110 when the receiving bluetooth device 120 operates in a receiving predetermined operation mode.

In practice, different functional blocks in the receiving-end bluetooth device 120 can be implemented by different circuits, or can be integrated into a single circuit chip. In addition, the receiving-end bluetooth transceiver circuit 121 may also be coupled to an additional antenna device (not shown), if necessary.
The triggering device 130 can be implemented by various devices that can generate corresponding user triggering signals according to simple operations of a user, such as buttons, switches, a remote controller, a touch screen, a voice control device, a gesture sensing device, a gyroscope, a circuit using other triggering signal generation technologies, or a combination of the foregoing devices. In practice, the triggering device 130 may be disposed outside the transmitting-side bluetooth device 110, or may be integrated into the transmitting-side bluetooth device 110.
The operation of the bluetooth communication system 100 will be further described with reference to fig. 2.
Fig. 2 is a simplified flowchart of an automatic pairing method for bluetooth devices according to an embodiment of the present invention. In fig. 2, the process in the column of a specific device represents the process performed by the specific device. For example, the portion in the column labeled "transmitting bluetooth device" represents the process performed by the transmitting bluetooth device 110; the portion in the column labeled "recipient bluetooth device" represents the flow performed by the recipient bluetooth device 120.
In operation, the receiver control circuit 125 may perform the process 202 at an appropriate time point according to the operation of the user or the operation command preset by the internal program, so as to control the receiver bluetooth device 120 to enter a receiver predetermined operation mode.
For example, the predetermined operation mode of the receiving end may be an Extended Passive Scan (LE Extended Passive Scan) mode.
For another example, the predetermined operation mode of the receiving end may be an Extended Active Scan (LE Extended Active Scan) mode.
For another example, the receiver-side predetermined operation mode may be a low power expansion Initiator (LE Extended Initiator) mode.
For another example, the receiver-side-scheduled operation mode may be a Periodic Scanning (Periodic Scanning) mode.
When the user wants to instruct the transmitting bluetooth device 110 to initiate an automatic bluetooth pairing procedure with other bluetooth devices, the user may perform a specific operation on the trigger device 130 to instruct the trigger device 130 to generate a corresponding user trigger signal. At this time, the receiving interface 117 proceeds to the process 204 to receive the user trigger signal generated by the triggering device 130.
When the receiving interface 117 receives the user trigger signal from the triggering device 130, the transmitting-end control circuit 115 proceeds to the process 206.
In process 206, the tx control circuit 115 may instruct the packet generation circuit 113 to insert an auto-pairing request and a source bluetooth device address corresponding to the tx bluetooth device 110 into one or more target packets. For example, the tx control circuit 115 may instruct the packet generation circuit 113 to insert the auto-pairing request and the source bluetooth device address together into a single target packet or to insert them into a plurality of target packets separately.
In the process 208, the tx control circuit 115 controls the tx bluetooth device 110 to enter a tx default operating mode.
For example, the predetermined operation mode of the transmitting end may be a Scannable (Scannable) mode.
For another example, the predetermined operation mode of the transmitting end may be a Connectable (Connectable) mode.
For another example, the aforementioned transmitting-end predetermined operation mode may be a Non-connectable (Non-connectable) mode.
For another example, the aforementioned predetermined operation mode of the transmitting end may be a Non-scannable (Non-scannable) mode.
For another example, the predetermined operation mode of the transmitting end may be a Periodic advertisement (Periodic advertisement) mode.
Next, the tx control circuit 115 proceeds to process 210 to control the tx bluetooth transceiving circuit 111 to transmit one or more target packets generated by the packet generating circuit 113.
In some embodiments where the tx-ue predetermined operation mode is a scannable mode, a connectable mode, a non-connectable mode, or a non-scannable mode, the one or more nominal packets referred to in the aforementioned flows 206 and 210 may be one or more auxiliary advertisement indication (AUX _ ADV _ IND) packets. Alternatively, the one or more target packets referred to in the aforementioned flows 206 and 210 may be a set of one or more advertisement extended indication (ADV _ EXT _ IND) packets and one or more auxiliary advertisement indication (AUX _ ADV _ IND) packets. In this case, if the receiving-end bluetooth device 120 is operating in the low power expansion passive scanning mode, the low power expansion active scanning mode, or the low power expansion initiator mode, the receiving-end bluetooth transceiver circuit 121 proceeds to the process 212 to receive one or more target packets transmitted from the transmitting-end bluetooth transceiver circuit 111.
In some embodiments where the tx-subscribed mode of operation is a non-reachable mode or a non-scannable mode, the one or more target packets referred to in the aforementioned flows 206 and 210 may be one or more auxiliary link indication (AUX _ CHAIN _ IND) packets. Alternatively, the one or more target packets referred to in the aforementioned flows 206 and 210 may be a set of one or more advertisement extension indication (ADV _ EXT _ IND) packets, one or more auxiliary advertisement indication (AUX _ ADV _ IND) packets, and one or more auxiliary link indication (AUX _ CHAIN _ IND) packets. In this case, if the receiving-end bluetooth device 120 is operating in the low power expansion passive scanning mode, the receiving-end bluetooth transceiver circuit 121 proceeds to process 212 to receive one or more target packets transmitted from the transmitting-end bluetooth transceiver circuit 111.
In some embodiments where the tx-SCAN mode is a scannable mode, the one or more nominal packets referred to in the processes 206 and 210 may be one or more auxiliary SCAN response (AUX _ SCAN _ RSP) packets. Alternatively, the one or more target packets referred to in the aforementioned processes 206 and 210 may be a set of one or more advertisement extension indication (ADV _ EXT _ IND) packets, one or more auxiliary advertisement indication (AUX _ ADV _ IND) packets, and one or more auxiliary SCAN response (AUX _ SCAN _ RSP) packets. Alternatively, the one or more nominal packets referred to in the aforementioned processes 206 and 210 may be a set of one or more auxiliary SCAN response (AUX _ SCAN _ RSP) packets and one or more auxiliary link indication (AUX _ CHAIN _ IND) packets. Alternatively, the one or more target packets referred to in the aforementioned processes 206 and 210 may be a set of one or more advertisement extension indication (ADV _ EXT _ IND) packets, one or more auxiliary advertisement indication (AUX _ ADV _ IND) packets, one or more auxiliary SCAN response (AUX _ SCAN _ RSP) packets, and one or more auxiliary link indication (AUX _ CHAIN _ IND) packets. In this case, if the receiving-side bluetooth device 120 is operating in the low-power extended active scanning mode, the receiving-side bluetooth transceiver circuit 121 proceeds to process 212 to receive one or more target packets from the transmitting-side bluetooth transceiver circuit 111.
In some embodiments where the tx-subscribed mode of operation is a non-reachable mode, a non-scannable mode, or a periodic advertisement mode, the one or more nominal packets referred to in the aforementioned flows 206 and 210 may be one or more auxiliary synchronization indication (AUX _ SYNC _ IND) packets. Alternatively, the one or more target packets referred to in the aforementioned flows 206 and 210 may be a set of one or more advertisement extension indication (ADV _ EXT _ IND) packets, one or more auxiliary advertisement indication (AUX _ ADV _ IND) packets, and one or more auxiliary synchronization indication (AUX _ SYNC _ IND) packets. In this case, if the receiving-side bluetooth device 120 is operating in the periodic scan mode, the receiving-side bluetooth transceiver circuit 121 proceeds to process 212 to receive one or more target packets from the transmitting-side bluetooth transceiver circuit 111.
Next, the packet parsing circuit 123 proceeds to process 214, parsing the one or more target packets received by the receiving-end bluetooth transceiver circuit 121 to obtain an auto-pairing request and a source bluetooth device address.
In the process 216, the sink control circuit 125 performs an auto-pairing procedure with the sender bluetooth device 110 through the sink bluetooth transceiving circuit 121 according to the received auto-pairing request and the source bluetooth device address.
The receiver control circuit 125 can be informed by the auto-pairing request that the bluetooth circuit corresponding to the source bluetooth device address allows other devices to perform bluetooth pairing with the sender bluetooth device 110. Therefore, the receiving-end control circuit 125 will automatically try to perform the bluetooth pairing procedure with the bluetooth device corresponding to the source bluetooth device address through the receiving-end bluetooth transceiving circuit 121, and will not generate the bluetooth device list for the user to select. In other words, the receiving bluetooth device 120 operates in the process 216 without any user intervention.
When the bluetooth auto-pairing procedure is completed, the receiving-side control circuit 125 and the transmitting-side control circuit 115 proceed to process 218 to establish one or more bluetooth connections between the transmitting-side bluetooth device 110 and the receiving-side bluetooth device 120, i.e., between the transmitting-side bluetooth transceiving circuit 111 and the receiving-side bluetooth transceiving circuit 121.
As can be seen from the foregoing description, when the operation modes of the transmitting-side bluetooth device 110 and the receiving-side bluetooth device 120 are consistent with one of the above embodiments, the user only needs to perform a simple operation (e.g., pressing a button, activating a switch, etc.) on the triggering device 130 coupled to the transmitting-side bluetooth device 110, and the receiving-side bluetooth device 120 automatically starts a pairing procedure with the transmitting-side bluetooth device 110 and establishes a bluetooth connection.
Therefore, the automatic pairing method for bluetooth devices described in the flowchart of fig. 2 is applicable to a bluetooth communication system using bluetooth 5.0 and the updated bluetooth communication standard.
On the other hand, in the process of the transmitting-side bluetooth device 110 and the receiving-side bluetooth device 120 automatically performing bluetooth pairing and establishing a bluetooth connection, it is not necessary for the user to issue a bluetooth device scanning instruction, and it is not necessary for the user to select a target device to be paired, so that the degree of user involvement can be greatly reduced.
It is obvious that the foregoing bluetooth communication system 100 can effectively simplify the bluetooth pairing procedure between two bluetooth devices, and improve the convenience of the user.
Furthermore, in the structure of the bluetooth communication system 100, both the transmitting-side bluetooth device 110 and the receiving-side bluetooth device 120 do not need to be provided with any display device, so the hardware structure, weight and volume of both the transmitting-side bluetooth device 110 and the receiving-side bluetooth device 120 can be greatly simplified.
In some embodiments, the tx control circuit 115 instructs the packet generation circuit 113 to insert the auto-pairing request and the source bluetooth device address into multiple target packets of different types in the flow 206. The method can effectively improve the data security of the automatic pairing request and the address of the source Bluetooth device in the transmission process.
Please note that the execution sequence of the process in fig. 2 is only an exemplary embodiment and is not limited to the actual implementation of the present invention. For example, there is no necessarily sequential relationship between the processes 202 and 204. In practice, the process 202 may be performed simultaneously with the process 204, or may be performed slightly later than the process 204.
Alternatively, the process 208 may be performed before the process 206, or may be performed simultaneously with the process 206. In some embodiments, the process 208 may also be performed before the process 204.
