Blue tooth module, blue tooth equipment and information processing method thereof

Abstract

The invention relates to a Bluetooth module, a Bluetooth device, and an information processing method thereof. The Bluetooth module comprises a RF transceiver which is used for receiving and sending a Bluetooth signal; a memory, which is used for memorizing a Bluetooth module application program, a Bluetooth protocol application program, a HCI driver and an assignment program; a baseband microcontroller, which is used for connecting with the RF transceiver to complete the bottom hardware application under HCI of a Bluetooth protocol stack, and is also used for connecting and driving the memory, transforming a control command into a corresponding HCI command, transforming the HCI command into a corresponding control event, transforming the response generated after the control command or the HCI command is executed into the corresponding control command response, and completing the software protocol application above the HCI of the Bluetooth protocol stack; and a communication interface, which is used for transmitting the control command, the control command response and the control event. The Bluetooth module is applied to develop the Bluetooth device, therefore, the design is simplified, the development time is shortened, and the developing and designing cost is saved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a bluetooth module, an electronic device using the bluetooth module and an information processing method thereof. Background technique [0002] Bluetooth (Bluetooth) is a short-range wireless communication technology that works in the 2.4GHz industrial, scientific, and medical (ISM) frequency band that is uniformly open to the world. Various electronic devices such as mobile devices, fixed communication devices, computers, set-top boxes, and vehicle systems equipped with Bluetooth technology can communicate with each other and exchange information wirelessly within a short distance (generally within 10m to 100m). [0003] The Bluetooth specification is the Bluetooth wireless communication protocol standard. It specifies the standards and requirements that Bluetooth applications should follow. According to the logical functions of the Bluetooth protocol, the Bluetooth protoco...

AI Technical Summary

Problems solved by technology

[0007] However, the above-mentioned HCI-based development needs to implement the Bluetooth software protocol application program on the host computer. For general development technicians, it is necessary to master the technical details of HCI, Bluetooth protocol stack and protocol application program in a short period of time, so as to develop a Bluetooth-compliant Regulating electronic devices presents considerable difficulty

[0008] Since the Bluetooth chipset only completes the underlying hardware applications below HCI, when developing Bluetooth devices with different functions, it is necessary to use different applications and Bluetooth protocol applications on the host. Therefore, the above-mentioned Bluetooth chipset is used to develop Bluetooth devices. It is not universal; and when developing new functions of Bluetooth devices, major modifications must be made to the existing applications and Bluetooth protocol applications on the host, which will increase the difficulty of development and design and prolong product development. cycles and slowing product development to market

[0009] In addition, due to the realization of the Bluetooth software protocol and its protocol application program on the host, the hardware and software requirements for the host are relatively high, and the development and design costs are relatively high. For example, the main processor on the host requires a 16-bit or even 32-bit Microcontroller (MCU) can realize the development of bluetooth function
