在使用wido的例程向yeelink发送传感器数据时，发送第一个数据，收到回复后，再发生地二个数据就死在哪里了。 如果把程序中接收服务器回复的程序去除，就可以不断上传数据。请求帮助！！ 附上例程 /*************************************************** * This is an example for the DFRobot Wido - Wifi Integrated IoT lite sensor and control node * Product Page & More info: https://www.dfrobot.com.cn/goods-997.html * Designed specifically to work with the DFRobot Wido products: * * The library is forked from Adafruit * * Written by Lauren * BSD license, all text above must be included in any redistribution * ****************************************************/ /* This example code is used to connect the Yeelink cloud service (Official homepage: www.yeelink.net).
