TCPClient 透传模式
AT+CWMODE=1 设置模组为STA模式
AT+CWLAP 查询附近 WIFI
AT+CWJAP_DEF="wifi_name","wifi_password" 连接路由器的 WIFI
AT+CIFSR 查看路由器分配给模组的IP地址,例如 192.168.43.103
AT+CIPMUX=0 设置单连接
AT+CIPMODE=1 设置透传模式
AT+CIPSTART="TCP","192.168.1.17",8899 连接TCP服务器
AT+CIPSEND 开始发送数据
> 进入发送模式
www*doit*am 发送数据
hello 接收数据
+++ 退出透传，直接发送。取消发送新行
