Hi,

Thanks for reporting this issue.
It looks like Bluetooth is turned off. Please, take a look at the Good Practices section in README.md file. You should fulfill requirements mentioned in this section:

• update Manifest
• check BLE support
• request Bluetooth access
• request Location access for API 23 and higher
• request runtime permissions for API 23 and higher

Take a look at the exemplary code snippet and examplary app.

Regards,
Piotr
