Broadlink app - "Added device setup option via bluetooth"

Noticed, the other day, on the tablet, while the app was updating (google play) and I checked the changes:

Updated: February 6, 2021

What’s New in Version 1.6.11:

    1. Added device setup option via Bluetooth
    1. Optimized device setup process
    1. Fixed minor issues

Any idea about what they are talking about?
Thought no Broadlink’s device had any kind of bluetooth hardware.
