I am using this library to listen to my favorite radios, from time to time (about 30-60min) the Esp32 reboots and then keeps rebooting for a few minutes immediately after the first sounds from the station comes out, then it functions normally again. Any ideas?

Not really. Sounds like a failing or too hot 3.3v LDO.

-EDIT: You could try disabling psram, as this is implemented rather buggy on most older esps.

OK thanks.

But if I disable PSRAM I will not have the ringbuffer?
..that will increase the risk of having clicks during streaming?
Why is a ringbuffer only implemented if PSRAM is present? Isn't it possible to implement it in RAM using one of the 2 cores of the esp32?

No ringbuffer without PSRAM. Normal RAM is too small for a second buffer.

..that will increase the risk of having clicks during streaming?

Yes, as the vs1053 is filled straight from the http buffer which has to fit in normal RAM.

Why is a ringbuffer only implemented if PSRAM is present? Isn't it possible to implement it in RAM using one of the 2 cores of the esp32?

Basically the same answer as the first question. Normal RAM is too small for a second buffer.

And for V0.0 ESP32 boards, I rarely have any dropouts listening without ringbuffer, but that might depend on your isp and which station you listen.

Thanks. I have an Adafruit_feather_esp32s3_tft with an Adafruit Music Maker FeatherWing , I like it because the esp32 and vs1053 are mounted one on top of the other with no wires (I had a lot of interference/instability when using a vs1053 board connected to the esp32 with Dupont wires).
Do you think my setup has good enough PSRAM? If not which esp32 board/vs1053 would you recommend?

[CelliesProjects]

That is a very nice combo. If Adafruit might ever stock up again on the featherwing boards I will get some myself.

Your hardware is more than capable.

[CelliesProjects]

To go back to your original question: I got no idea.

Which app do you use to tune in? Which station?

[CelliesProjects]

And maybe you could run the following code to actually see what hardware revision you have.

#include <Arduino.h>
#include <esp_chip_info.h>

/* https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/external-ram.html#chip-revisions */

void setup() {
#if defined(CONFIG_IDF_TARGET_ESP32S2) && ARDUHAL_LOG_LEVEL != ARDUHAL_LOG_LEVEL_NONE
    delay(3000);
    Serial.setDebugOutput(true);
#endif
    Serial.begin(115200);

    /* Print chip information */
    esp_chip_info_t chip_info;
    esp_chip_info(&chip_info);
    Serial.printf("This is ESP32 chip with %d CPU cores, WiFi%s%s\n",
            chip_info.cores,
            (chip_info.features & CHIP_FEATURE_BT) ? "/BT" : "",
            (chip_info.features & CHIP_FEATURE_BLE) ? "/BLE" : "");

    Serial.printf("silicon revision %d\n", chip_info.revision);

    Serial.printf("%dMB %s flash\n", spi_flash_get_chip_size() / (1024 * 1024),
            (chip_info.features & CHIP_FEATURE_EMB_FLASH) ? "embedded" : "external");
}

void loop() {
}

OK thanks

On S2 and S3 boards the psram issues are fixed, so with your S3 board you should have no psram issues. — Reply to this email directly, view it on GitHub , or unsubscribe .

I would like to listen to an italian radio that broadcasts in HLS:
https://radioitaliasmi.akamaized.net/hls/live/2093120/RISMI/master.m3u8
I have found some code developed for the M5stack that is supposed to decrypt HLS:
https://github.com/Yokohama-Miyazawa/M5HLSPlayer
It has a file
AudioGeneratorTS.cpp
that is supposed to decrypt the .ts files (demux?)
i was wondering if it is possible to use it to get an .aac file from the .ts using this converter (?) and pipe it to your ESP32_VS1053_Stream.cpp. I would like to learn more about all this to be able to do that but I could not find useful documents online that explain how to demux with an esp32...

[CelliesProjects]

For the rebooting problem I think I found the solution.

https://github.com/CelliesProjects/ESP32_VS1053_Stream#prevent-reboots-while-playing

Let me know if it works for you.

[lidense]

I have revision V3, so I put "-D BOARD_HAS_PSRAM" in platformio.ini and it seems to work OK.
Do you have any idea concerning the HLS question above (2 days ago)?
Thanks and regards

[CelliesProjects]

Closing as solved.
