I want to connect my esp32 to my android on which I have enabled bluetooth tethering enabled it's 4G data. The problem is that the HTTP client on esp32 needs a wifi client but I don't want to use wifi due to power inefficiency. Is there any HTTP library that could use GET method...
1. Running WIFI STA to commuicate with phone, BLE to commuicate and locatilze with other esp32, BT audio a2dp to play music with another esp32. 2. Using WebSockets to authorize the server to retrieve data, using MQTT or other protocol to transmit and receive data from server. ...
First, the client establishes a WebSocket connection through a WebSocket handshake. The handshake starts with an HTTP request that allows all the required services to handle HTTP connections and WebSocket connections. Once the connection is established, both the ESP32s can send and receive dat...
在ESP32CAM端直接下载示例代码udp_server这个历程,修改默认的WIFI和密码,启动之后会输出如下结果 由此我们知道了UDP的地址和端口IP地址为192.168.2.3,端口为3333 此时我们使用小工具NetAssist.exe来测试,选择UDP协议之后向ESP32CAM的地址发送广播,如下图所示
I have seen this http://blog.podkalicki.com/esp32-wifi-sniffer/ to receive all packet with the promiscuous mode, i just need to find somthing to send custom packet, now because this work find . I have seen this https://github.com/Jeija/esp32free80211 but that was not compatible now...
