Bluetooth Serial Read getting 0 bytes always

Ionic Native

I have used subscribeRawData to read the data from the connected device but whiling reading, it gives the buffer length 0 always .

Below is the sample code :-

connect() {

this.platform.ready().then(() => {

  this.Bs.isEnabled().then(
    () => {
      console.log('BT is enabled !');

      this.scanForBTDevices();

    },
    (error) => {
      console.log('BT is not enabled On load . Enabling now .. !');

      this.Bs.enable().then(
        () => {
          console.log('Bluetooth is enabled now');

          this.scanForBTDevices();

        },
        (error) => {

          console.log('Not able to enbable bluetooth !');
          console.log(JSON.stringify(error));
        }
      )
    }

  );
});

}

scanForBTDevices() {

this.Bs.list().then(
  (data) => {

    console.log('Getting the list of devices paired with the mobile. Note you need to pair first the device you want to use , then it will be available in this list');

    console.log(JSON.stringify(data));

    this.deviceList = data;

    this.Bs.connect('MAC-Address').subscribe(
      (data) => {
        console.log('Connected to device !');
        console.log(JSON.stringify(data));

        this.subscribeForData();
      },
      (error) => {
        console.log('Error in connecting the device');
        console.log(JSON.stringify(error));
      }
    )
  },
  (error) => {

    console.log('Error in getting the list of paired Devices !');

    console.log(JSON.stringify(error));
  }
)

}

subscribeForData() {

this.Bs.subscribeRawData().subscribe(
  (data) => {

    console.log('Subscribing for the data successfull' + JSON.stringify(data));

    this.Bs.read().then(
      (data) => {

        console.log('Getting the Data now');

        console.log(JSON.stringify(data));

        let buffer = new Uint8Array(data);

        console.log("Converting it into Uint8Array")
        console.log(console.log(buffer));
      },
      (error) => {

        console.log('error in getting the data');

        console.log(JSON.stringify(error));
      }
    )
  },
  (error) => {

    console.log("Error in Subscribing for the data !");
  }
)

}

disconnect() {
this.Bs.disconnect().then(
(data) => {

    console.log('Successfully Disconnected from Device');
  },
  (error) => {

    console.log('Error in disconnecting from device');

    console.log(JSON.stringify(error));
  }
);

}

Any help would be appreciated. Thanks :slight_smile:
