Users who use the official website MCU_SDK for development, only need to download the latest SDK compression package, and replace the original project file and re-transplant. Users who directly connect to the protocol: 1) In the sending frame format, the third byte "version" data is changed to 0x03 2) The command word 0X02 is to query product information, and the reply content format needs to be changed. For details, please refer to the protocol document example. 3) The command word 0X03 is the device networking status, and two statuses will be added. If you write the fixed check value directly, please note that the check value changes due to the version change.
