Bluetooth Low Energy Scanning Error
k3nt last edited by k3nt
I'm getting a consistent error with the bluetooth scanning examples in Qt 5.4.1 on the Pi. When a scan is attempted, this error is received: QBluetoothDeviceDiscoveryAgent::InputOutputError. I am using the Plugable USB-BT4LE adapter: http://plugable.com/products/usb-bt4le (uses BCM20702 chipset). I am able to use hcitool and do an lescan just fine. The examples work just fine on my linux desktop with the same exact usb dongle. I've also tried using two different versions of bluez, (4.99-2) and 5.3.
I found this persons post, which is the same exact issue with another popular usb bluetooth dongle.
Any help would be much appreciated!
