The handshake phase and the packet transceiving phase can be described simply as: after the WiFi module sends an upgrading instruction to the electric control MCU, the MCU immediately enters an upgrading mode to prepare for the xmodem to receive data, at the moment, a receiver firstly sends a signal to initiate transmission (the signal can determine which data verification mode the sender transmits the data), if the sender does not send the data, the receiver needs to wait for 3 seconds overtime and then sends the signal to request the data transmission, until no data response of the sender exists within 30 seconds, the handshake is considered to be failed, the MCU exits the upgrading mode and is restarted to enter the original working state; when the sender receives the request signal sent by the receiver, an instruction ready for sending is immediately returned to the receiver, and the handshake is successful. After the handshake of the receiver and the sender is successful, the sender starts to send data to the receiver through each frame of data, the receiver needs to send an ACK signal to confirm the correct data transmission, if the data transmission is wrong, a NAK signal is sent, the sender needs to reinitiate the data transmission after receiving the NAK signal, and if the data transmission is nearly completed, the sender needs to send an EOT signal to finish the data transmission;
