BLE writeValue到外设

Question

我无法将值写入BLE设备。 我翻译了这个：

NSLog(@"Writing value for characteristic %@", interestingCharacteristic);
    [peripheral writeValue:dataToWrite forCharacteristic:interestingCharacteristic
        type:CBCharacteristicWriteWithResponse];

到Swift：

peripheral.writeValue("Writing value for characteristic", forCharacteristic: interestingCharacteristic, type: CBCharacteristicWriteWithResponse)

但是我得到了Use of unresolved identifier 'CBCharacteristicWriteWithResponse'的错误

我是iOs编程的新手，并尝试了多种方法使其正常工作，但那不会发生。 你能帮我吗。

Answer 1

您已经将NSLog语句和writeValue方法组合成某种奇怪的混搭。

你想要的是

println("Writing value for characteristic \(interestingCharacteristic)")
peripheral.writeValue(dataToWrite, forCharacteristic:interestingCharacteristic, type: CBCharacteristicWriteType.WithResponse)
