why does esp32-lyrat running a2dp_sink example without output ?

Postby mkseven32 » Tue Apr 24, 2018 9:59 am

Hi all
i have config the a2dp_sink example as like below
A2DP sink output as I2S codec;
GPIO setting :

| ESP pin | I2S signal |
| :-------- | :----------- |
| GPIO25 | LRCK |
| GPIO26 | DATA |
| GPIO5 | BCK |

when bt linked to smartphone, while playing muisc, there is a log shows bt is works fine, but there is not any voice out!

does any wrong of the setting ?

BR !

The ES8388 codec on board of ESP32 LyratT requires configuration.

Have you tried pipeline_bt_sink example instead?

I2S GPIO assignment of the ESP32 LyraT is listed under https://esp-adf.readthedocs.io/en/lates ... header-jp4 and your setting for the three I2S signals is the same.

Hi
do you mean the example of pipeline_bt_sink in the esp-adf ?
it is OK,but i found there is less info about make menuconfig in Readme file .

anyway , the examples is so unstable,when esp broad linked to smart phone,first time play music is OK, but when smart phone take a phone, the linked could not relinked again。

For the the 'pipeline_bt_sink' there is no need to configure I2S pins using menuconfig.
Related configuration is hidden in the driver 'esp-adf/components/audio_hal'
