Problem with Bluetooth on Raspberry Pi 3 Model B

Hi everyone!

From time to time my built-in Bluetooth stops working on Raspberry Pi 3 Model B. On this model I also have a USB-camera. I’ve read somewhere that there could be a problem in work between USB devices and built-in Bluetooth. As I was experimenting with Bluetooth stick, it has correctly detected my phone devices, but didn’t work with Xiaomi BLE Temperature and Humidity sensor. I have used no name Bluetooth stick.

Can anyone advice on a Bluetooth stick which would correctly work with both:
Xiaomi BLE Temperature and Humidity sensor
and with Bluetooth device trekking?

Thanks!
