我在使用ESP32 的A2DP Sink 功能进行开发的时候遇到客户反馈,A2DP 播放的前几秒都会有噪音,后面就会逐渐改善噪音消失。后来我使用官方开发板ESP32-LyraT 运行A2DP_Sink 官方例程 进行验证,结果发现蓝牙连接后首次播放或者停止播放后等待几秒钟再重新播放都会有这个噪音,于是我使用示波器+逻辑分析仪扫描波形发现是I2S 向...
1. 确保ESP32设备已经正确配置并编译了a2dp_sink示例。 2. 在ESP32设备的蓝牙设置中,将设备名称设置为一个独特的名称,这样手机在搜索时可以轻松找到它。 3. 在ESP32设备的蓝牙配置中,启用自动连接功能。这可以通过设置ESP32设备的蓝牙配置参数来实现。在`bluetooth_init()`函数中,可以添加以下代码: ```c esp_...

The documentation for the ESP32-c3 is indicating that A2DP should be working: see https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/api-reference/bluetooth/classic_bt.html Compiling your a2dp_sink example gives the following ...
Postbyespgtxs»Wed Apr 17, 2019 2:30 am 失能蓝牙,反初始化,关闭主任务 然后,再次初始化,开启蓝牙、主任务,可以连接蓝牙,但是不能作为音频设备连接上。 只能用一次的蓝牙音箱,不符合要求啊! 测试代码如下: Code:[Select all][Expand/Collapse]
I have a problem with the esp32 a2dp sink mode connected to a smartphone. If the smartphone's Bluetooth version is 4.2, connected OK and volume up and down is worked OK. But if the smartphone's Bluetooth version is 5.0, connected OK but volume up and down is not worked. There is ...
It will be helpful to debug the issue if you provide the following info: 1. What is the remote device (A2DP source) used here? 2. Have you tried using ESP32 as a remote device (with A2DP source example)? Thanks.2 posts • Page 1 of 1 Return to “ESP-IDF” Jump to Who...
