[0081] In view of the current Bluetooth communication protocol, the flexibility is poor and the application scenarios are limited. This embodiment can establish a first communication connection supporting two-way communication between two communication devices. When one of the communication devices detects the Bluetooth When the communication trigger condition is satisfied, it can be used as the current master communication device, and send a master-slave communication notification to another communication device currently serving as the slave communication device through the first communication connection, and then establish a Bluetooth communication connection as the AG end with the slave communication device as the HF end , this embodiment is referred to as the second communication connection; after the slave communication device receives the master-slave communication notification, it completes the registration of the HF role and sets itself to a state where Bluetooth cannot...

[0133] For ease of understanding, this embodiment is described on the basis of the foregoing embodiments and a specific application scenario as an example.
[0134] In this embodiment, the two communication devices are respectively a wrist phone and a mobile phone supporting Bluetooth communication, and both the wrist phone and the mobile phone support the AG function and the HF function. An eSIM card may or may not be set in the wrist phone. In this embodiment, the foregoing first communication connection is described by taking a Bluetooth peer-to-peer communication connection as an example.
[0135] In the application scenario of this embodiment, the following bluetooth communication environment can be used but not limited to:
[0136] The standard software interface (Host Controller Interface, HCI) layer is suitable for managing HCI status, controlling HCITRAMS, processing events / data (event / data) on HCI TRAMS according to HCI format and protocol, assembling truncated data...

[0158] This embodiment provides a communication device. For the type of the communication device, refer to the description in the foregoing embodiments, and details are not repeated here. See Figure 7 As shown, the communication equipment includes:
[0159] Processor 701, memory 702, transmitter 703, receiver 704, memory 702 is used to store the first computer program;
[0160] When the first computer program is executed by the processor 701, the transmitter 703, and the receiver 704, the steps performed when the communication device in the communication method described above is used as the master communication device are implemented;
[0161] And / or, the memory 702 is used to store the second computer program; when the second computer program is executed by the processor 701, the transmitter 703, and the receiver 704, the communication device in the above-mentioned communication method is implemented as a slave communication device. each step.
[0162] This embodiment al...
