Expected Behavior

Getting results from “startDeviceScan” method in android

Current Behavior

Previously it worked on an android device but after an upgrade of react-native from 0.60.4 to 0.60.5 it does not work anymore … Downgrading back to 0.60.4 doesn’t solve my problem … Everything works fine in IOS.

And yes permissions are set in the APP …

 manager.startDeviceScan(null, null, (error, scannedDevice) => {

            if (error) {
                // no error given
                console.info(error);

I had a similar issue, but I did a battery reset for the BLE devices, which caused them to advertise themselves for scanning.
