arduino-esp8266开发tcp客户端

Question

esp8266 nodemcu使用arduino作为tcp客户端，同时连接传感器和wifi，实时向python编程的tcp服务端传输传感器数据。
主要发现有三点问题：

• 一个是传输和接收的速率并不一致，arduino这边串口监视器显示一秒钟大概有几十次传输记录，但是python那边接收并没有这么快

• 第二个问题更关键，每隔几秒数据传输就会卡顿一两秒的样子，这样采集的数据就不完整了

• 第三个就是Python接收数据经常会有空包和不完整的数据，例如发送我是中国人，会接收到“我”，然后再接收到“是中国人”
  望各位能指点一下怎样让数据传输更稳定，尤其是第二个问题最致命，其他两点至少数据还是连贯的。

import socket

import time  

# 创建socket
tcp_server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 本地信息
address = ('192.168.111.145', 7788)

# 绑定
tcp_server_socket.bind(address)

tcp_server_socket.listen(128)
recv_head=''
while True:
    # 等待新的客户端连接
    client_socket, clientAddr = tcp_server_socket.accept()
    #print('client:', client_socket)
    #print('addr:', clientAddr)
    
    while True:
        # 接收对方发送过来的数据
        recv_data = client_socket.recv(10240)  # 接收1024个字节
        recv_data = recv_data.decode('gbk')
        
        if len(recv_data)==0:
            break
        elif len(recv_data)<60:
            recv_head = recv_data
            continue
        else:
            print('接收到的数据为:', recv_data)
            
            print(time.strftime("%Y-%m-%d %H:%M:%S",time.localtime()))
            recv_head = ''
            break  
        
tcp_server_socket.close()

这是python代码和arduino代码
