Embodiment Construction

[0014] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for ease of description, the drawings only show a part but not all of the content related to the present invention.

[0015] In this embodiment, the communication method between the Android upper client and the STM32 bottom layer is used for sensor data transmission. Firstly, various sensors connected to the STM32F103 main control board collect data, and after the main control board performs data processing, the data is sent to the PC through the wireless serial port module.

Abstract

The invention discloses a communication method between an Android upper layer client and an STM32 bottom layer. Through FTDI USB to R232, the micro USB data information of the Android upper client computer can be converted into RS232 serial port data information. The Android upper-layer client converts the data information format into RS232 through FTDI USB to RS232, and the RS232 serial port information is converted into TTL information through the RS232 level-to-TTL level module, and then received by the underlying STM32. On the contrary, STM32 transmits information to the upper layer of Android, which is exactly the opposite conversion process. The invention solves the technical problem that the Android upper layer client cannot directly communicate with the bottom layer STM32 through the serial port.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a communication method between an Android upper-layer client and an STM32 bottom layer. Background technique [0002] Information conversion is the key to control communication between the Android upper client and the STM32 bottom layer. The Android upper layer client cannot directly communicate with the bottom layer STM32 through the serial port. And in serial communication, it is easy to lose data. And it is a non-handshake protocol, that is, the sender does not know whether the receiver receives the sent information. Summary of the invention [0003] The purpose of the present invention is to solve the technical problem that the Android upper-layer client cannot directly communicate with the lower-layer STM32 through the serial port. [0004] The present invention provides a communication method between an Android upper-layer client and an STM32 bottom layer to realiz...
