Problems solved by technology

However, the basic I2C bus, SPI bus or BLE master-slave communication method simply transmits and receives data, and does not provide data packaging and integrity verification functions; therefore, it is not suitable for efficient data transmission, nor can it be used for Timely and effective detection of data errors caused during transmission
[0007] Therefore, there is a lack of technical means for efficient and error-free data communication between the external host and the hearing device in the prior art

Abstract

The invention provides a method and device for performing data transmission with a hearing device, wherein the method for performing data transmission comprises the steps of: sending an initial command to the hearing device, wherein the initial command at least comprises the communication address, the first reading and writing length and the first command identifier of the hearing device; the first reading and writing length is used for indicating the data length for performing transmission with the hearing device; and the first command identifier is used for indicating a command type needingto be executed by the hearing device; waiting for the pre-set time, so that the hearing device checks and analyzes the initial command within the pre-set time, and executes an action corresponding toan analysis result; sending a reading request command to the hearing device, wherein the reading request command at least comprises a communication address and the second reading and writing length; and the second reading and writing length is used for indicating the data length needing to be received from the hearing device; and receiving execution data sent by the hearing device according to thereading request command. According to the scheme in the invention, the transmission process and the data transmission format are optimized; and thus, high-efficiency and accurate data transmission can be realized.

Description

technical field [0001] The invention relates to the field of embedded communication, in particular to a method and device for data transmission with a hearing device. Background technique [0002] Embedded systems have been widely used in many fields, and hearing devices are gradually implemented using embedded systems. [0003] Hearing devices, such as hearing aids, cochlear implants, and various types of headphones, have become an indispensable part of daily life for many hearing-impaired and normal-hearing people. The shape of the hearing device has gradually shrunk from the traditional box-type machine worn on the body to the concealed earphone that is directly inserted into the ear canal; the internal signal processing method of the hearing device has also developed from the analog circuit to the current digital signal processor (Digital Signal Processor). Processor, referred to as DSP). It is precisely because of the emergence of digital signal processors that the cu...
