I've managed to send raw data buffer through the WiFi Interface (STA connection) when the Interface's mac address matches the source mac of the DataFrame. If the Source Address in the DataFrame differs from the Wifi's mac, then the frame is discarded. Is there a possibility to get rid ...
代码中,首先定义了一个结构体,包含几种不同类型的数据变量,这个就是我们要发送的数据,在setup()中先设置WiFi工作在STA模式,然后调用esp_now_init()初始化,将配对设备的信息进行添加,简单配置一下发送回调函数,打印是否发送成功,主函数中,每2秒发送一次数据。esp_now_send返回是否发送出去,回调函数中展示是否成功发...

仅需修改send_img_aliyun.ino中 WIFI 账号与密码 和 阿里云物联网平台三元组(见下图)即可,aliyunmqtt.cpp与aliyunmqtt.h文件无需修改任何内容。由于 ESP32cam 性能问题,send_img_aliyun.ino中将一个图片分为多段进行传输,每段为 800,详见代码。
蓝牙配网,可以提供更便捷的配置,但是有的型号(比如ESP32-S2)不支持蓝牙,无法使用;且蓝牙内存资源占用大,在配网完成前,同时启动蓝牙和WIFI可能用户程序的内存空间就不够了,必须在配网完成后关闭蓝牙重新初始化。SmartConfig和Airkiss存在不支持5G网络,配网成功率低,小程序放弃支持等问题。 如果设备有可以采集音频(其实...
My application is to receive the data from master(stm32) through spi protocol and send the received data to Wi-Fi through an UDP protocol. So I have created the two tasks one for spi and another for wifi. The speed of wifi is getting around 3Mbps but my application is to reach 50Mbp...
