NSLocalizedDescription=Writing is not permitted
0
I tried to make an app that sends messages from iPhone to Bluetooth LE module. But for some reason, it gives the following error:
NSLocalizedDescription=Writing is not permitted.
Even though the types of the blePeripheral and the blePeripheral!.write are CBCharacteristicWrite.withResponse, the error says that writing is not permitted. How come the following code does not work for me?
func writeValue(data: String) {
let valueString = (data as NSString).data(using: String.Encoding.utf8.rawValue)
//change the "data" to valueString
if let blePeripheral = blePeripheral {
if let txCharacteristic = txCharacteristic {
blePeripheral.writeValue(valueString!, for: txCharacteristic, type: CBCharacteristicWriteType.withResponse)
}
}
}
func writeCharacteristic(val: Int8) {
var val = val
let ns = NSData(bytes: &val, length: MemoryLayout<Int8>.size)
blePeripheral!.writeValue(ns as Data, for: txCharacteristic!, type: CBCharacteristicWriteType.withResponse)
}

"the types of the blePeripheral and the blePeripheral!.write are CBCharacteristicWrite.withResponse" You mean the properties oftxCharacteristic?

If I am not mistaken, txCharacteristic is for sending messages from my phone to a BLE module. So I am trying to permit the phone to send the data, but why does the xcode says to me that the permission is not allowed?

When you did indidDiscoverCharacterstic():txCharacteristic = characteristic, could you add print("tx properties: (txCharacteristic.properties)") and give the output?

The app prints the following statements:Found 1 characteristics!Rx Characteristic: FFE1Tx Characteristic: FFE1

It doesn't answer if the property is writable or not.
