- Basic Example:
This example demonstrates how to use the Classic Bluetooth source of the ESP-ADF. In this example, one development board (source) acquires the MP3 audio file from the HTTP server over Wi-Fi, decodes the audio, and then sends it to the other development board (sink) via the Classic Bluetooth A2DP profile.
The pipeline for the development board to acquire the MP3 file on the HTTP server and decode it for sending is as follows:
[http_server] ---> http_stream ---> mp3_decoder ---> bt_stream_writer ---> [Bluetooth]
This example runs on the boards that are marked with a green checkbox in the table. Please remember to select the board in menuconfig as discussed in Section Configuration below.
This example supports IDF release/v3.3 and later branches. By default, it runs on ADF's built-in branch $ADF_PATH/esp-idf.
The default board for this example is ESP32-Lyrat V4.3. If you need to run this example on other development boards, select the board in menuconfig, such as ESP32-Lyrat-Mini V1.1.
menuconfig > Audio HAL > ESP32-Lyrat-Mini V1.1
Connect to Wi-Fi first. Go to menuconfig to configure the Wi-Fi connection information.
menuconfig > Example Configuration > `WiFi SSID` and `WiFi Password`
Connect to the Classic Bluetooth sink first. Go to menuconfig to configure the device name of the remote sink. The default name is ESP-ADF-SPEAKER.
menuconfig > Example Configuration > (ESP-ADF-SPEAKER) BT remote device name
Build the project and flash it to the board, then run monitor tool to view serial output (replace PORT with your board's serial port name):
idf.py -p PORT flash monitor
To exit the serial monitor, type Ctrl-].
See ESP-IDF Programming Guide for full steps to configure and build an ESP-IDF project.
- After the example starts running, it connects to the Wi-Fi first. After a successful connection, the development board starts searching for the sink device "ESP_ADF_SPEAKER". The log is as follows:
