在IDF的example里有个ESP-NOW的例子,这个例子里设置了WIFI的协议, ESP_ERROR_CHECK( esp_wifi_set_protocol(ESPNOW_WIFI_IF, WIFI_PROTOCOL_11B|WIFI_PROTOCOL_11G|WIFI_PROTOCOL_11N|WIFI_PROTOCOL_LR) ); 假设现在有2个设备A和B,A通过ESP-NOW广播的方式发送数据,A怎么确定是用那种协议发送的?在网络中可能...

初始化ESP-NOW; 注册接收回调函数(OnDataRecv)。收到消息后将执行的功能。 在该回调函数内部,将消息保存到变量中以执行具有该信息的任何任务。 ESP-NOW与设备接收消息或发送消息时调用的回调函数一起使用(您可以确定消息是否已成功发送或失败)。 ESP-NOW有用的功能 以下是最基本的ESP-NOW功能的摘要: 函数名称和...
Now run: make flash This compiles both the ESP IDF libraries and the example main file locally (into thebuilddirectory) and then downloads this to the flash memory on the device over USB. It will take a little while, both to compile, and to flash. If you have a multi-core machine ...

Simply tried to use the "Zigbee_on_Off_Light" example from the "File"->"Examples"->"ESP32"->"Zigbee" Set "zigbee mode" and "partition scheeme" and hit the "Verify" button. I get a new error now: Compiling library "Zigbee" "C:\Users\m\AppData\Local\Arduino15\packages\esp32\hard...

For example, the older ESP32-Lyra32T V2 and ESP32-LyraT boards were rectangular with built-in touch-based controls. The ESP32-LyraTD-MSC Audio-Mic HDK (hardware development kit) combines the ESP32-LyraTD-MSC (“audio-mic development board”) with a secondary “top” board. The kit ...
