turning off bluetooth

biospank

Hi all,

I was monkey testing my app and tried to turn off bluetooth while the app was running. I noticed a bug that is probably caused by my side but the error stack is all about MetaWearBleService:

Firmware v. 1.0.3

Android MetaWear api v 1.8.0

Any suggestion would be greatly appreciated.

Cheers.

That line of code corresponds to code that is setting up the Bluetooth gatt descriptors.  It would appear that turning off the BT radio will return a null for getDescriptor method.
