FlooGoo FMA120 - LE Audio Broadcast Features; Public Broadcast Mode; High-Quality Music Broadcast Settings; Encrypted Broadcast Content

There are five settings for LE audio broadcast.
Public broadcast.
When enabled, the public audio broadcast (PBP) feature is activated,
and the dongle functions as a Public Broadcast Source (PBS). When disabled,
the dongle operates as a Broadcast Media Sender (BMS) as defined in TMAP.
Broadcast high-quality music.
When enabled, the dongle will use a 48 kHz sample rate for music
content during broadcasting. When disabled, the dongle will utilize a 16 kHz
sample rate for voice content.
Encrypt broadcast.
If enabled, an encryption code is used to restrict access to the broadcast
content, similar to a Wi-Fi access code, and only those receivers that know the
code can access it.
Broadcast name.
This is a human-readable string for the receiver to distinguish between
multiple nearby broadcasters.
Broadcast code.
This is an encryption code to be used in the broadcast. When the input
code length is less than 16 bytes, it will be padded to 16 bytes with zeros.
