Setup problem

So I have everything setup properly( I guess). So what happens is, whenever I am trying to call startDeviceScan(), it is not being called or is stuck at something, no clue!

Context

Here's my code:

`constructor() {
    super()
    this.manager = new BleManager()
    this.state = {info: "", values: {}}

    this.scanAndConnect = this.scanAndConnect.bind(this);
  }

   info(message) {
    this.setState({info: message})
  }

  error(message) {
    this.setState({info: "ERROR: " + message})
  }

  updateValue(key, value) {
    this.setState({values: {...this.state.values, [key]: value}})
  }

   componentDidMount() {
    if (Platform.OS === 'ios') {
      this.manager.onStateChange((state) => {
        if (state === 'PoweredOn') this.scanAndConnect()
      })
    } else {
      this.scanAndConnect()
    }
async function requestLocationPermission() 
{
  try {
    const granted = await PermissionsAndroid.request(
      PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
      {
        'title': 'Example App',
        'message': 'Example App access to your location '
      }
    )
    if (granted === PermissionsAndroid.RESULTS.GRANTED) {
      console.log("You can use the location")
      alert("You can use the location");
    } else {
      console.log("location permission denied")
      alert("Location permission denied");
    }
  } catch (err) {
    console.warn(err)
  }
}
requestLocationPermission();
  }

    scanAndConnect() {
      this.info("Start Scan");
      console.log("Scanning")
    this.manager.startDeviceScan(null,
                                 null, (error, device) => {
      this.info("Scanning...")
      console.log(device)

      if (error) {
        this.error(error.message, )
        return
      }

      if(device) console.log(device);
      if (device.id === 'F4:BC:DA:57:D7:CC' || device.name === 'JBL Flip 3 SE') {
        this.info("Connecting to JBL FLip")
        this.manager.stopDeviceScan()
        device.connect()
          .then((device) => {
            console.log("Yohooo");
            this.info("Discovering services and characteristics")
            return device.discoverAllServicesAndCharacteristics()
          }).catch(err => console.log(err));
          // .then((device) => {
          //   this.info("Setting notifications")
          //   return this.setupNotifications(device)
          // // })
          // .then(() => {
          //   this.info("Listening...")
          // }, (error) => {
          //   this.error(error.message)
          // })
      }
    });
  }

What platform do you test on? Where are native logs as per the issue template request?

Hey, I'm using OnePlus 6, Android 10 (OxygenOS version 10.3.1). The logcat log is as follows:

Do you have permission for fine location granted? Are Location Services on?

ShashwatMDas commented 4 years ago

Do you have permission for fine location granted? Are Location Services on?

Yes, fine location permissions are granted and are checked everytime the app refreshes, so that won't be an issue.

dariuszseweryn commented 4 years ago

And what about Location Services (GPS)?

ShashwatMDas commented 4 years ago

And what about Location Services (GPS)?

As per the docs, we were required to include this: <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Also react native docs also state the same thing for geolocation services. Is anything else required?

dariuszseweryn commented 4 years ago

Location Services. Top bar (usually), location switch — must be turned on. This is something different than Location Permission. Both are needed.

Afair the library should raise an error if it is off when starting the scan but I cannot be sure if it does on this new Android.

ShashwatMDas commented 4 years ago

Yes, the location switch is on and the app is able to receive location services from the phone. Even bluetooth services are properly received. startDeviceScan method return this error if I turn of bluetooth: BluetoothLE is powered off Which means the library should be integrated fine. It's just that whenever bluetooth is on and it should be scanning for devices, the method doesn't show any logs.

dariuszseweryn commented 4 years ago

Could you show native logs after you have set the log level to Verbose in the library?

This is the complete log with log level verbose

dariuszseweryn commented 4 years ago

Nope. I mean, again, per issue template: setLogLevel. I see no native logs from the library in what you just pasted. Please set the library log level to verbose as well and then paste the logs.

ShashwatMDas commented 4 years ago

Yeah so i did this, this.manager.setLogLevel(LogLevel.Verbose);

I have pasted the complete log over here (since I have no idea what all information you are looking for). Thanks

Scanning seems to start normally. Could you check if nRF Connect application will show any devices?

I have several ideas:

Bluetooth stack on your phone has gone off. Try restarting the phone
You try to connect to a device that is not a BLE peripheral but a classic Bluetooth one
Your device is already connected to the phone so it is not advertising itself

Sorry for late reply, got caught up in work. Thanks a lot it worked. Turns out restarting the phone was all I needed to do. Closing the issue with this.
