Introduction to Bluetooth modes
1. Classic Audio (1-to-1)
MoerLink™ is backward compatible with non-LE Audio Bluetooth receivers. When the receiver is not a LE Audio device,
it will connect using the traditional Bluetooth mode pairing method.
2. LE Audio (1-to-1)
If the receiver is a Bluetooth device that supports LE Audio (including Bluetooth receivers, Bluetooth headsets, Bluetooth
speakers, etc.), it will automatically use lossless/high-resolution decoding technologies to play music.
3. Broadcast audio (Auracast™) (1-to-N).
Broadcast mode is only compatible with LE Audio devices, and there is no limit on the number of receiver-end devices.
No pairing is required in broadcast mode, as long as MoerLink™ broadcast mode is enabled, the receiver-end devices
can search and connect by themselves (operating range up to 30~50 meters).
