我正在使用 Ionic 构建一个应用程序，并且我正在尝试使用bluetoothLE从 arduino 向我的应用程序发送一个简单的字符串。
我正在使用带有 HM-10 蓝牙适配器的 Arduino，我设法连接和断开设备，但无法理解如何发送或接收数据。
只是为了测试它，我一直在尝试 write 方法，并在 arduino 上有一个简单的脚本，通过串行通信寻找任何类型的数据，但没有成功。
这是我正在使用的方法：
$rootScope.writeH =function(address, serviceUuid, characteristicUuid, value) {
var string = "H";
var bytes = bluetoothle.stringToBytes(string);
var encodedString = bluetoothle.bytesToEncodedString(encodedString);
var params = {address:address, serviceUuid:serviceUuid, characteristicUuid:characteristicUuid, value:encodedString};
console.log("Write : " + JSON.stringify(params));
$cordovaBluetoothLE.write(params).then(writeSuccess, writeError);
}
这就是我调用函数的方式：
<div class="col">
<a class="button button-balanced button-small" ng-click="writeH(selectedDevice.address, selectedService.uuid, selectedCharacteristic.uuid)">Write H</a>
</div>
我正在使用运行 iOS 9 的 iPhone 6。
这是我的 Arduino 草图，此时我只是想获取任何数据：
char val; // variable to receive data from the serial port
int ledpin = 8; // LED connected to pin 48 (on-board LED)
void setup() {
pinMode(ledpin, OUTPUT); // pin 8 (on-board LED) as OUTPUT
Serial.begin(9600); // start serial communication at 9600bps
}
void loop() {
if( Serial.available() ) // if data is available to read
{
val = Serial.read(); // read it and store it in 'val'
}
if( val == NULL ) // if any NO data was received
{
digitalWrite(ledpin, LOW); // LED is OFF
} else {
digitalWrite(ledpin, HIGH); // otherwise turn it ON
delay(2000);
}
delay(100); // wait 100ms for next reading
}
编辑：
我正在使用 HM10 芯片，我刚刚尝试了这个应用程序：http: //itunes.apple.com/us/app/hm10-bluetooth-serial/id1030454675 ?mt=8它运行良好，只需要更改设置“写而不响应” - 我不确定我在我的 javascript 中使用什么样的写，这可能是问题，因为“写有响应”将不起作用。
编辑2：
刚刚从蓝牙cordova插件检查了iOS的源文件，写入类型设置为无响应，所以不是......
//Write Type
NSString *const writeTypeNoResponse = @"noResponse";
