Bluetooth communication method, communication equipment and system

[0039] Example 1

[0040] To solve the technical problem in the prior art, the present invention provides a Bluetooth communication method for the Bluetooth main device (hereinafter referred to as the master device) and the Bluetooth slave device ((hereinafter referred to as slave device)) One-way signal data transmission; that is, the master transmitted signal data to the slave device, or the main device transmits signal data to the master; wherein the signal data comprises, but not limited to, audio data, video data. Or other continuously collected signal data.

[0041] The master device is based on a standard Bluetooth protocol and a custom Bluetooth protocol, and the custom Bluetooth protocol includes a custom Bluetooth protocol, including a custom packet rule and a custom unpacking rule; The custom packet rule is configured to compress the signal data to be transmitted to form a corresponding signal data packet; the custom unpacking rule decodes the signal data packet to obtain

[0071] In a specific embodiment, the rendering process is executed, including: the first signal data that has not yet transmitted is added to the first signal data to be transmitted, and the new first signal data is formed; The first signal data size is greater than the active information size of the first standard Bluetooth package, if, then directly obtain a new first signal data packet according to the original data compression rate; whether, according to the new first A signal data size, and the data size of the effective information in the first standard Bluetooth package, determines the new data compression ratio of the first signal data, which is greater than the previous data compression ratio; based on the new data The compression ratio is compressed to the new first signal data to obtain a new first signal packet.

[0072] Wherein, the original data compression ratio is the data compression ratio used in fragmentation and compression encoding when the first signal data is p

[0083] In order to solve the technical problem in the prior art, the present invention provides another Bluetooth communication method, which is suitable for bidirectional signal data transmission between the main device and the slave device.

[0084] The master device is based on a standard Bluetooth protocol and a custom Bluetooth protocol, which is the same as the custom Bluetooth protocol in Example 1, which is not Take it again.

[0085] The master device transmits the first signal data to the slave device in the first data transmission window, and transmits the second signal data from the device to the second data transmission window.

[0086] See Figure 5 The flow schematic of another Bluetooth communication method is shown in the present embodiment. Such as Figure 5 As shown, the Bluetooth communication method includes the following steps:

[0087] S21, the master device, according to the custom packet rule, fragmentation and compression encoding according
