Arduino programming uses esp8266 as the TCP client and python programming as the TCP server,the transmission will be stuttered every once in a while

[zbxs]

sometimes some empty packets and incomplete data are received, and the most importantly the data transmission will be stuttered every once in a while,,which greatly affects the experimental data acquisition.please help me.
