React-native-ble-plx: device.name always null when scanning

[pawel125]

Hi!
For several days I try to connect to any BT device. First, I was building my application using https://www.polidea.com/blog/ReactNative_and_Bluetooth_to_An_Other_level/, but I could not connect to my device. I've found out that program stops in scanAndConnect() function, because no device name fits to the one that I am looking for. I've used function like this to find that devices can be detected:

scanAndConnect() {
let device;
let x = 0;
this.manager.startDeviceScan(null, null, (error, device) => {
console.log(x);
console.log(error);
console.log(device.name);
x = x+1;
});
}

but the result is always like this:
I/ReactNativeJS(16857): 5882
I/ReactNativeJS(16857): null
I/ReactNativeJS(16857): null
I/ReactNativeJS(16857): 5883
I/ReactNativeJS(16857): null
I/ReactNativeJS(16857): null
etc.

my code is the one from issue #83 proposed by @Cierpliwy, I have put everything in my github repo: https://github.com/Pa-well/BtTest

My device is Arduino HC-05 BT modul, and I can connect to it from other applications, so it works. Devices are paired. Am I missing something obvious?

Ok, I have found that this lib supports only BLE devices,
That was really obvious :)

Hi @pawel125
I have tested whether my device supports BLE or not.It supports BLE but its name is not showing.

Thank you.
