Hello, I am designing multimedia system. My esp32 board is pico mini v2. The other master board transmit mp3 data via SPI. Data can be received and be decodec succesfully. But in driver audio functions wants to data alligned 4. For example my data length is not a multiple of 4. Is this problem for ...

Hello,

in ADF there is example for playing music from sd card. But I want to play music from spi peripheral. ESP32 will be slave microcontroller STM32 will be Master. STM32 will transmit mp3 data via SPI. So;
This is for sd card example
[sdcard]-->fatfs_stream-->mp3_decoder-->resample-->i2s_stream ...

Thank you so much, It worked thanks to you.

No, it didn't work. I tried ENCODE, DECODE, BOTH and none of them worked. This card uses two codecs, one of them is adc codec es7243 and the other is dac codec es8311. So I think I should select BOTH options but it didn't work.

Hi, did you solve the problem? I am also developing with Lyrat Mini, but in the example you gave, the A2DP part works without any problems, while the HFP part does not work. The microphone does not detect or transmit sounds during a call.

Hello, I am trying to make hands free with esp32 lyrat mini development board, but the pipelien_hfp and pipeline_a2dp_hfp examples in the sample codes do not work correctly. I selected lyrat mini via menuconfig. It connects to bluetooth, but its microphone does not work when making a phone call. The ...

In esp32 pipeline hfp example, microphone and speaker are set in i2s settings with this line
#define I2S_STREAM_CFG_DEFAULT() I2S_STREAM_CFG_DEFAULT_WITH_PARA(I2S_NUM_0, 44100, I2S_DATA_BIT_WIDTH_16BIT, AUDIO_STREAM_WRITER)
so i2s set for microphone was not working correctly, that was why ringbuf ...

In the hfp example, I successfully connect to the phone via Bluetooth. Then, when I make a phone call to use the hands-free feature, I get an error as follows:

I am doing a multimedia project with esp32 vroom. I am currently doing my experiments on esp32 LyraT mini. There is a vrover-e processor on lyrat mini and I can play music via bluetooth and make phone calls via microphone in hfp format on this card. I did not see any difference between vrover and ...

hello, I am developing a project with esp32 Lyrat mini v1.2. in the hfp example in the sample codes, my master device does not connect to esp and I get this error.
after flashing the codes to my esp device, my screen is in the form of picture 1 and picture 2. When I try to connect to Bluetooth, the ...
