您的ESP32 BLE 服务器已准备就绪! 转到下一部分,创建一个连接到服务器的 ESP32 客户端,以访问温度和湿度特性,并获取读数以在 OLED 显示器上显示它们。 2) ESP32 BLE 客户端 在本节中,我们将创建 ESP32 BLE 客户端,它将与 ESP32 BLE 服务器建立连接,并在 OLED 显示屏上显示读数。 示意图 ESP32 BLE ...
When acting as a server, ESP32 advertises its existence to nearby client devices. Once the client devices scan for available Bluetooth devices the server establishes connection between them and transfers the data from server to client device. This communication is called point to point. In this t...
I need some help regarding BLE communication between ESP32 and Android / IOS . (2 ways communication). I have existing project that works great with Android mobile phone by using OTG USB cable. I want to do the communication with BLE instead USB cable. ...
I try to send 60kByte of data over BLE between two ESP32. As a start, I used the blecent example from NimBLE/ESP-IDF and so far the communication works great and reliable, but the speed is extremly slow. It seems, that I can only send exactly every 100ms a packet and I really ...
