How may the issue got resolved? image

You are probably running on an emulator or device that doesn't have Bluetooth. That is why it is throwing this error as it can't get its name. If you have no way around it, and wish to get rid of Bluetooth support altogether this is a quick fix

For android: Edit this file: ./node_modules/react-native-bluetooth-cross-platform/android/src/main/java/com/rctunderdark/NetworkCommunicator.java

At line 25, replace:

private String displayName = BluetoothAdapter.getDefaultAdapter().getName();

by whatever name:

private String displayName = "Whatever"

This will fix the error, but disable bluetooth. Or better yet, try...catch to see if Bluetooth is available then get its name

The same procedure should work for IOS, even though I have never tried it. Hope it helps.
