1. Design background

Currently, wearable devices are everywhere, and more and more people are paying attention to health and joining the ranks of sports. The Bluetooth base station designed for smart running shoes is mainly used in school classrooms and gyms. Taking school classrooms as an example, schools and parents pay attention to students' daily exercise and learning, combining work and rest. Students wear smart shoes and place Bluetooth base stations in the classroom. Without getting rid of mobile phones, they can still collect the exercise status of each student on that day. When students are in class, the base station automatically connects to the smart shoes via Bluetooth and obtains the number of steps, and stores the student ID and the number of steps. After a day's class, the teacher can use the PC software to check the students' situation that day. During class, the teacher can also use the PC software to control the connection to the specified smart shoe device.

3. Function introduction

1. Two modes (the default mode is transparent transmission when powered on):

1.1 Transparent transmission mode PC software sends data to GD32F350, and GD32 sends the data through the Bluetooth module. In the opposite direction, after receiving the Bluetooth data, it sends the data to the PC software through the serial port. 1.2 Independent mode The Bluetooth base station controls the Bluetooth module to scan, connect, get ID, get steps, store data and other operations. 2. Transparent mode workflow void USART0_IRQHandler() { uint8_t tmp = 0; tmp = usart_data_receive(USART0); if(v32_uartx == USART0) { b_tp_receive_data(&tmp, 1); } else { uart1_write_ch(tmp); } } Due to the transparent mode, the command parsing does not need to be performed by GD32, so UART0 is directly input and UART1 is output. The data is parsed by PC software; 374492 Transparent transmission mode connects to the device and obtains the total number of steps is 347 steps 3. Independent mode workflow Independent mode is divided into several steps: Start scanning--->Filter broadcast name--->Record MAC address to prevent connecting to the same device in a short time--->Connect device--->Get ID--->Get steps---->Store and disconnect--->Loop Interaction process

After independent mode, switch to transparent mode and synchronize data to see the data and ID

I would like to ask, did you write the host computer yourself?

Yes, QT is very convenient

For people with zero computer programming ability, this is a difficult thing. They can only make a living by stealing other people's software

liklon, can you record a functional demonstration video of your work?
