好的,以下是一个简单的ESP32-C3蓝牙组网程序,用于将多个ESP32-C3设备组成一个网络:
```
#include <BLEDevice.h>
#include <BLEUtils.h>
#include <BLEServer.h>
// 定义一个服务UUID
#define SERVICE_UUID "4fafc201-1fb5-459e-8fcc-c5c9c331914b"
// 定义一个特征UUID
#define CHARACTERISTIC_UUID "beb5483e-36e1-4688-b7f5-ea07361b26a8"
BLECharacteristic *pCharacteristic;
void setup() {
Serial.begin(115200);
BLEDevice::init("ESP32-C3");
BLEServer *pServer = BLEDevice::createServer();
BLEService *pService = pServer->createService(SERVICE_UUID);
pCharacteristic = pService->createCharacteristic(
CHARACTERISTIC_UUID,
BLECharacteristic::PROPERTY_READ |
BLECharacteristic::PROPERTY_WRITE
);
pService->start();
BLEAdvertising *pAdvertising = BLEDevice::getAdvertising();
pAdvertising->addServiceUUID(SERVICE_UUID);
pAdvertising->setScanResponse(true);
pAdvertising->setMinPreferred(0x06); // 指定最小广告间隔时间(以0.625ms为单位)
pAdvertising->setMinPreferred(0x12); // 指定最大广告间隔时间(以0.625ms为单位)
BLEDevice::startAdvertising();
}
void loop() {
String value = pCharacteristic->getValue().c_str();
if (value == "CONNECT") {
Serial.println("Device connected");
} else if (value == "DISCONNECT") {
Serial.println("Device disconnected");
}
delay(1000);
}
```
此程序将创建一个蓝牙服务和特征,可以通过读取和写入特征值来实现设备间的通信。当设备连接时,将会打印 "Device connected",当设备断开连接时,将会打印 "Device disconnected"。可以根据自己的需求修改程序来实现更复杂的功能。
