BleManager Scan Fails

Tell us which versions you are using:

• react-native v0.61.5
• iOS/Android v.9.1.0

Hi,

I am trying to use the ble-manager library. My first test was run the example and I can see the devices connected in my android using the getConnectedPeripherals() method.

Now, I wanna to list all the idle bluetooth devices.. for to do it I am using the scan method.

BleManager.scan([], 10, true).then(results => { console.log('Scanning...'); this.setState({scanning:true}); });

The behavior in my android 9.1.0 is an error when I called the scan method.

//isNull - ReadableNativeMap.java:102 //scan - LollipopScanManager.java:48 //scan - BleManager.java:176

I think the error is here: if (scanManager != null) scanManager.scan(serviceUUIDs, scanSeconds, options, callback);

But I am not sure about this issue.

Please, can anyone help me with this, I dont know if there is any compatible problem or something like this.

Tks
