How does the TWS solution work?

Firstly, there have two Bluetooth speakers both using TWS Bluetooth module, paring the two TWS Bluetooth audio modules, regarding one speaker as “DB01”(Which can scan another TWS Bluetooth module and be connected by smartphone), another TWS Bluetooth module will be “DB02”(Can be scanned/connected by DB01 and receive audio from DB01)

Secondly, smartphone searches and scan DB01 Bluetooth TWS speaker and connect with it.

The true wireless system has been established successfully, when smartphones play music, audio in stereo will play by the two speakers.
