react-native - react native ble plx：写入失败后断开连接

Question

情况是onPressIn我需要向 ble 设备发送写入命令，直到onPressOut被触发。

这是我的writeMessage功能

  const writeMesage = async (message = 'c1') => {
// bleManager.cancelTransaction(transactionId);
const senddata = base64.encode(message);
if (deviceId) {
  const isConnected = await bleManager.isDeviceConnected(deviceId);
  if (!isConnected) {
    await bleManager
      .connectToDevice(deviceId, { autoConnect: true, requestMTU: 200 })
      .then((device) => {
        (async () => {
          const services =
            await device.discoverAllServicesAndCharacteristics();
          const characteristic = await getServicesAndCharacteristics(
            services
          );
        })();

        return device.discoverAllServicesAndCharacteristics();
      })
      .then((device) => {
        console.log('then2', { device: device });
        // return this.setupNotifications(device)
        return true;
      })
      .then(
        () => {
          console.log('Listening...');
        },
        (error) => {
          console.log('Connection error' + JSON.stringify(error));
        }
      );
    await bleManager.stopDeviceScan();
  } else {
    await bleManager
      .writeCharacteristicWithoutResponseForDevice(
        deviceId,
        serviceUUID,
        characteristicsUUID,
        senddata
      )
      .then((characteristics) => {
        console.log({ characteristics });
      })
      .catch((e) => {
        console.log({ e });
      });
  }
  return;
} else {
  console.log('No device is connected');
}
};

我正在实施它：

<TouchableOpacity
                style={{
                  display: 'flex',
                  height: 50,
                  width: 50,
                  borderRadius: 100,
                  borderColor: '#58C2A2',
                  justifyContent: 'center',
                  alignItems: 'center',
                  backgroundColor: '#1A8E6B'
                }}
                disabled={isLocked}
                onPressIn={() => {
                  let interval = setInterval(() => {
                    writeMesage('c1');
                  }, 20);
                  setPressUpInterval(interval);
                }}
                onPressOut={() => clearInterval(pressUpInterval)}
              >
                <Image source={upArrow} />
              </TouchableOpacity>

它一直工作到发现写入失败，然后设备断开连接。
