swiftui - If send from peripheral to central an Int(38), I receive (38) but if I send Int(3847) I receive (7) how can I get the correct value?

 var manager: CBCentralManager!
 var peripheral: CBPeripheral!
 var readCharacteristic: CBCharacteristic?
 var writeCharacteristic: CBCharacteristic?
 var notifyCharacteristic: CBCharacteristic?

@Published var data:[UInt8] = [0,0]{
            didSet{
                send(data)
                print("0?? Dato Inviato: (data)")
            }
        }


func peripheral(_ peripheral: CBPeripheral, didUpdateValueFor characteristic: CBCharacteristic,
                    error: Error?) {
      switch characteristic.uuid {


if let value = characteristic.value {

if self.feedbackRfid == true {
                    self.rfid = value.byte()
                    print(" (rfid)")
 

func byte() -> String{
        return map{
            String(UInt32($0))
        }.joined()
    }
