How to Configure BT631D Module as a BIS Receiver

James

We're developing a wireless audio system and plan to use the BT631D module as a BIS (Broadcast Isochronous Stream) receiver to sync audio from a central BIS transmitter (gateway). The goal is to achieve synchronized multi-room audio broadcasting from a single source for background music applications.

James To configure the BT631D as a BIS receiver and connect to your BIS gateway, follow these steps:

Quick Setup Guide:

Set Profile:
First, configure the module for LE Audio headset mode:

    AT+PROFILE=17577

Scan for Gateways:
Search for available BIS transmitters nearby:

    AT+SCAN=4

The module will list detectable BIS gateways after scanning.

Connect to Gateway:
Use the gateway name from the scan results to connect:

    AT+BISCONN=<BISgateway_name>

Key Points:

Ensure the BIS gateway is powered on and broadcasting before scanning.
The module will automatically sync to the audio stream after a successful connection.
