4. โหมดการทำงาน

The eppfun LE Audio Bluetooth 5.4 Transmitter supports both Classic Bluetooth (BT) and Broadcast Audio (BA) modes.

4.1 Classic Bluetooth (BT) Mode (1-to-1 Connection)

In BT mode, the transmitter connects to a single Bluetooth headphone or speaker, providing a dedicated audio stream. This is suitable for private listening.

4.2 Broadcast Audio (BA) Mode (1-to-Many Connection)

In BA mode, the transmitter can broadcast audio to multiple compatible headphones or speakers simultaneously. This is ideal for sharing audio with several listeners in the same room, such as watching a movie with family or friends. This mode offers low latency and is particularly useful with LE Audio compatible devices.
