This example configures LinkIt 7697 to act as a simple GATT server with1 characteristic.
To use it,open AppInventor project:*
Build & install it on Android id
created Mar 2017*/#include <LBLE.h>#include <LBLEPeriphral.h>// Define a simple GATT service with only 1 characteristic
LBLEService ledService("19B10010-E8F2-537E-4F6C-D104768A1214");
LBLECharacteristicInt switchCharacteristic("19B10011-E8F2-537E-4F6C-D104768A1214", LBLE_READ | LBLE_WRITE);
void setup(){// Initialize LED pin
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, LOW);//Initialize serial and wait for port to open:
Serial.begin(9600);// to check if USR button is pressed
pinMode(6, INPUT);// Initialize BLE subsystem
LBLE.begin();while(!LBLE.ready()){
delay(100);}
Serial.println("BLE ready");
Serial.print("Device Address = [");
Serial.print(LBLE.getDeviceAddress());
Serial.println("]");// configure our advertisement data.// In this case, we simply create an advertisement that represents an
// connectable device with a device name
LBLEAdvertisementData advertisement;
advertisement.configAsConnectableDevice("BLE LED");// Configure our device's Generic Access Profile's device name
// Ususally this is the same as the name in the advertisement data.
LBLEPeripheral.setName("BLE LED");// Add characteristics into ledService
ledService.addAttribute(switchCharacteristic);// Add service to GATT server (peripheral)
LBLEPeripheral.addService(ledService);// start the GATT server - it is now
// available to connect
LBLEPeripheral.begin();// start advertisment
LBLEPeripheral.advertise(advertisement);}
void loop(){
delay(1000);
Serial.print("conected=");
Serial.println(LBLEPeripheral.connected());if(digitalRead(6)){
Serial.println("disconnect all!");
LBLEPeripheral.disconnectAll();}if(switchCharacteristic.isWritten()){
const char value = switchCharacteristic.getValue();
switch (value){case1:

課程，太棒了，如果有一系列資料，就太感謝了

請問如果以APP INVENTOR本身有的藍芽客戶端來連結7697可以這樣寫嗎?
#include
#include
void setup() {
Serial.begin(9600);
pinMode(13,OUTPUT);
pinMode(14,OUTPUT);
}
void loop() {
if(Serial.available()>0)
{
char data = Serial.read();
if (data == ‘a’)
{
digitalWrite(13,HIGH);
delay(1000);
digitalWrite(13,LOW);
}
else if(data == ‘b’)
{
digitalWrite(14,HIGH);
delay(1000);
digitalWrite(14,LOW);
}
}
}
您好，不行啊… 因為7697不支援傳統藍牙，所以一定要用 BluetoothLE 元件喔
請教一下這幾個參數意義?
serviceUuid / characteristicUuid
signed 是指要加密嗎?
serviceUuid / characteristicUuid 是 BLE 兩邊所要設定的 ID，請參考 https://zh.wikipedia.org/zh-tw/%E8%93%9D%E7%89%99%E4%BD%8E%E5%8A%9F%E8%80%97
另外 signed 是指”有號數” 有一個位元會用來表示正負數。
