BLE writeValue to peripheral

Question

I am having trouble to write values to a BLE device. I translated this:

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

to Swift:

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

But I get the error Use of unresolved identifier 'CBCharacteristicWriteWithResponse'

I am new to iOs programming and tried manyfold ways to make it work but it just wouldn't happen. Can you help me please.

Answer 1

You have combined the NSLog statement and the writeValue method into some sort of bizarre mashup.

What you want is

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