OK. I get the memory issue. However, could a workaround be that when an io pin used to change from one mode t the other the esp is forced to reboot? The selected mode could be stored in nvram and checked on boot as to which mode is required?

Maybe, it might be possible to allocate or deallocate BT memory once, I'm not sure. You'll have to test it.

Setting up the environment atm and I'll look into it. I also happen to have an m5stack core so will take a look at working with that. I look forward to contributing as I get up to speed :-)

Hi MrBuddy,
i wrote a icy-meta-parser for this projekt and like to share it.
Only little changes in http-fifo-files with example in app_main.c for Monitoring.
Please contact me ritaripp@gmx.de to send files.
:idea:
kodera2t/ESP32_OLED_webradio seems not to be interested.

regards
Reini

Rebooting...
ESP32_MP3_Player branch master, git commit 91e2f15, submodules updated
esp-idf git commit branch release/v3.0, commit daf1d055, submodules updated

(aside: is there any need to update the submdoules to a specific checkout when checking out a branch? If so, how?)

I've got BT support on, but I get the same CPU hang with BT support turned off. This is my BT config:

Code: Select all

 --- Bluedroid Enable
       The cpu core which Bluedroid run (Core 0 (PRO CPU))  --->
 (3072) Bluetooth event (callback to application) task stack size (NEW)
 [ ]   Bluedroid memory debug (NEW)
 [*]   Classic Bluetooth
 (2048)  A2DP sink (audio stream decoding) task stack size (NEW)
 [*]   Include GATT server module(GATTS) (NEW)
 [*]   Include GATT client module(GATTC) (NEW)
 [*]   Include BLE security module(SMP) (NEW)
 [ ]   Close the bluedroid bt stack log print (NEW)
 (4)   BT/BLE MAX ACL CONNECTIONS(1~7) (NEW)
What can I do to resolve this?

Here viewtopic.php?t=1026&start=80#p7783 i have read something about #define DAC_BUG_WORKAROUND but i can't find it.

I am new on esp32. it would be very nice if someone can help me.
thank you.

Hi,

i've found this: https://www.waveshare.com/uda1380-board.htm
Would that work? Looks good, Line IN Line OUT and MIC IN ;-)
It has I2S, but not sure about the MCLK

Dear all,

I'm trying to run ESP32_MP3_Decoder with a MAX98357A board from Aliexpress and a 4R speaker from Aliexpress.
The speaker measures 4R with my multimeter.
I'm powering the whole thing from a 1A USB charger.
I've tried powering the MAX98357A board from the regulated 3.3V from the ESP32 board and directly from Vin on the ESP32 board (4.5V in my case).
make monitor shows that a stream is playing (buffering at about 95-99%).
I've measured LCR, BCLK and DIN with an oscilloscope and these look good (see the screenshots), but there's no audible output on the speaker.
Measuring the speaker output with an oscilloscope shows some regular gibberish with frequencies of 250KHz and above.
What can I be doing wrong?
Is it possible that the USB charger doesn't give enough current to power the MAX98357A?

Please ignore my previous message.
This was an issue with the MAX98357A board.
OUT(-) on the QFN was not soldered, Do'h!
Never happened to me before on a factory assembled board.
