Question

我对Arduino 101上的BLE外设有以下疑问：

可以在广告包中通告任何特征值（动态数据）而不是UUID。如果是这样的API是什么？我的目标是在adv数据包中获取任何温度数据，而不是连接到外设。

当前观察：我只能使用API setAdvertisedServiceUuid和setLocalName来宣传服务uuids和本地名称。

2.在下面的代码中，我能够在第一个实例中启动并捕获广告，但在字母实例中，begin具有错误的返回值。我做错了吗？我们的想法是开始和停止广告，甚至可能更改广告数据。

#include <CurieBle.h>


void setup() {  
    // set LED pin to output mode
    pinMode(ledPin, OUTPUT);
    Serial.begin(9600); 
}

void loop() {  
    //BLE Peripheral
    BLEPeripheral * blePeripheral = new BLEPeripheral; 

    //Set the Local Name
    blePeripheral->setLocalName("MyDevice");

    //Start Advertising
    blePeripheral->begin();

    //Run the advertisement for 20 seconds
    delay(20000);

    //Stop the advertisement
    blePeripheral->end();

    //Delete the BLE Peripheral
    delete blePeripheral;

    //Wait 5 seconds before starting the next adv
    delay(5000);
}

任何帮助将不胜感激。

感谢。 Swaroop

BLEPeripheral blePeripheral;  // BLE Peripheral Device (the board you're programming)
BLEService ledService("19B10000-E8F2-537E-4F6C-D104768A1214"); // BLE LED Service

// BLE LED Switch Characteristic - custom 128-bit UUID, read and writable by central
BLEUnsignedCharCharacteristic switchCharacteristic("19B10001-E8F2-537E-4F6C-D104768A1214", BLERead | BLEWrite);
