执行D:\Portable\arduino-1.8.12\hardware\espressif\esp32\tools 目录下的get.exe: 1. 我估计你在下载xtensa-esp32-elf-win32-1.22.0-80-g6c4433a-5.2.0.zip工具时,大概率会卡很久,因为这个工具非常大。 实际上,这个get.exe本质就是下载esptool-2.6.1-windows.zip、mkspiffs-0.2.3-arduino-esp32-win32...
ESP32-0.96寸OLED作为BLE Client与ESP32-BME280 BLE Server通信 总结 简介 两个ESP32开发板,一个ESP32挂载一个BME280传感器读取温湿度值并通过BLE低功耗蓝牙GATT协议发送数据,另一个ESP32通过BLE低功耗蓝牙与ESP32-BME280建立连接并在0.96寸OLED显示出BME280的温湿度值, ESP32-BME280作为BLE Server BME280传感器...
Before you can start working with BLE communication on the ESP32 and Arduino Nano 33 BLE Sense, you need to set up the required software and libraries. Here's how you can do this using both the Arduino IDE and the Arduino Web Editor: Arduino IDE Install the Arduino IDE: If you haven'...

Demo 26: How to use Arduino ESP32 I2S to play wav music file from sdcard Demo 27: How to use Arduino ESP32 BLE (Bluetooth Low Energy) as a GATT server Demo 28: How to use Arduino ESP32 BLE (Bluetooth Low Energy) as a GATT client ...
二. ESP32 arduino 蓝牙BLE通讯的实现 1. 思路 把蓝牙设备看作服务器, 把手机看作一个客户端, 客户端可以给服务器发送数据, 服务器可以给客户端下发通知 实现思路: 创建BLE设备 BLEDevice::init(ble_name); 创建BLE服务器 BLEServer *pServer = BLEDevice::createServer(); 创建若干服务 BLEService *p...
请注意:GATT的Client、Server身份与GAP的中心、外围设备没有任何关系,它们可以任意搭配,甚至可以既是Server又是Client。 GATT Server的数据层级结构图: BLE发送长度限制: 20 Byte 一般限制长度会变成20,主要原因:core spec里面定义了ATT的默认MTU为23个bytes,除去ATT的opcode一个字节以及ATT的handle 2个字节之后,剩下...
找到官方例程 examples/bluetooth/bluedroid/ble/gatt_serve (gatt(Generic Attribute Profile,通用属性配置文件) 就不用理这词;GATT Server简单来说是 被动的一方,等待GATT Client发起连接请求) 第二难:build.ninja… 如果同一份代码之前烧过其他的芯片 —— 需要clear一下(遇事不决… 应该是flash或配置文件什么的问...
2. GATT 协议 3. UUID 4. 项目概述 4.1 材料清单 4.2 ESP32 BLE 服务器 4.3 ESP32 BLE 客户端 参考资料 1. BLE 服务器和客户端 蓝牙低功耗设备有两种:服务器和客户端。ESP32 既可以作为客户端,也可以作为服务器。 服务器宣传它的存在,所以它可以被其他设备发现和包含客户端可读数据。客户扫描附近的设备,...
such as GATT, UUID, and other characteristics of BLE. In the end, we saw the ESP32 BLE in Arduino IDE. We implemented an example to do so and used the BLE Scanner app for this. In the end, we saw how the built-in examples of Arduino IDE can perform the tasks. I hope it was ...
