ios - 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)

但我得到错误Use of unresolved identifier 'CBCharacteristicWriteWithResponse'

我是 iOs 编程的新手，尝试过多种方法让它工作，但就是行不通。你能帮帮我吗？

Answer 1

您已将 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)
