mp3-http-stream example works on esp32 but not on esp32s2-wrover OR lolin_s2mini

[ptunstall]

Wifi connection and mp3 steaming work perfectly on an esp32-wroom via:

mcconfig -d -m -p esp32 ssid="SSID_NAME" password="password"

But the same command ran on both the esp32-s2-wrover and the lolin_s2mini never even connect to wifi.

Anyone experience this?

Cool that the MP3 streaming is working for you. That's a powerful capability.

The two boards you mention use the ESP32-S2 chip. When you build with -p esp32 you are building for the original ESP32 chip. You need to indicate which board to build for. For the two boards you mention that would be:

mcconfig -d -m -p esp32/lolin_s2mini ssid="SSID" password="PASSWORD"
mcconfig -d -m -p esp32/saola_wrover ssid="SSID" password="PASSWORD"

Our ESP32 documentation lists supported boards along with the platform/sub-platform ID to use when building.

Oh yes, Apologies I was changing to the correct target device. It uploads fine, just xsbug says "lost connection" where as the regular esp32 connects and begins playing.

Thanks for the clarification. We'll take a look.

What audio output device are you using and how is it connected?

I am able to reproduce the problems you're having with the lolin_s2mini and saola_wrover. I'll have a fix for it soon.

Hey! I am using i2s via the max98357A i2s amplifier. There's just a simple 3w 8ohm speaker on the other end of this i2s amp.

For the saola_wrover, try replacing $MODDABLE/build/devices/esp32/sdkconfig-s2-psram/sdkconfig.defaults with the contents of this gist:

https://gist.github.com/mkellner/b244fa68827cef830236f956b09db8c6

My max98357 is connected to pins 1, 2 and 3.

In the defines section of $MODDABLE/build/devices/esp32/targets/saola_wrover/manifest.json, I have:

    "defines": {
        "audioOut": {
            "bitsPerSample": 16,
            "numChannels": 1,
            "volume_divider": 2,
            "i2s": {
                "bitsPerSample": 16,
                "bck_pin": 2,
                "lr_pin": 3,
                "dataout_pin": 1
            }
        }
    }

With that, I can run mp3-http-stream successfully.

Let me know how it works for you.

This works perfectly on the saola_wrover! the s2mini seems to work correctly too with the output in xsbug but I can't get audio out on pins 3,5,7 but thats most likely an error on my end. Going to solder the rest of the pins in a bit so I can use 1,2,3 like you're doing on the saola.

Can also conform that the elevenlabs example also works WHICH IS FLIPPIN NEATO!!!!

Really appreciate you guys so much for this!!!

For the lolin_s2mini, change this file:

$MODDABLE/build/devices/esp32/targets/lolin_s2mini/sdkconfig/sdkconfig.defaults

Change the line:

CONFIG_SPIRAM_USE_CAPS_ALLOC=y

to

CONFIG_SPIRAM_USE_MALLOC=y

If you have problems try building clean first.

mcconfig -d -m -p esp32/lolin_s2mini ... -t clean

[ptunstall]

YES! This works perfectly for the lolin s2mini!!! Wizards! THANK YOU!!
