Thanks a lot..
I will check connecting the debugging assistant.
Regarding the library, I downloaded the Tuya_WiFi_MCU_SDK and when I try to compile he code in Arduino IDE, I get below errors
#error "Please call uart_receive_input(value) in the serial port receive interrupt. The serial port data is processed by MCU_SDK. The user should not process it separately. Delete the line after completion."
#error "Please fill in the MCU serial port send function and delete the line"
#error "Please call this function where you need to cache multiple bytes of serial port data at a time. The serial port data is processed by MCU_SDK. The user should not process it separately, and delete the line after completion行"
#error "Please process the reportable data and report only the data. After the processing is completed, delete the line"
#error "Please implement the wifi function test success/failure code by yourself. Please delete the line after completion"
#error "Please add wifi_uart_service() directly in the while(1){} of the main function, call this function without adding any conditional judgment, delete the line after completion."
#error " Please add wifi_protocol_init() in the main function to complete the wifi protocol initialization and delete the line."
