Arduino Nano ESP32 / Lolin S3 mini: Serial output not working

[ricardoquesada]

Bluepad32 + Arduino IDE currently does not work as expected using Arduino Nano ESP32.

fixed. confirmed by jjs357 user. It is working Ok now.

I tried to follow the guide, but it is not working for me right now. I have an Arduino Nano ESP32 and a PS4 Controller.

@Freihaendich wait until v4.0-beta2 is released.... alternative use develop branch of https://github.com/ricardoquesada/esp-idf-arduino-bluepad32-template

re-opening... using "print" works Ok, but not with Serial.printf()... WTF... something is wrong with UART... not sure what.

[ricardoquesada]

Same issue with the Lolin S3 Mini. What these two boards have in common is that the share the UART and USB OTG ports... they have just one port.

And Serial, instead of being redirected to "right" port, it gets redirected somewhere else (?).

[ricardoquesada]

Having "USB CDC on Boot : Enabled" fixes the issue...

But the bug seems to be that "boards.txt" is not being used correctly, because nano_nora entry (the Arduino Nano ESP32) has nano_nora.build.cdc_on_boot=1.

And that would explain why the Arduino Nano ESP32 gets recognized as a different board

Something seems to be happening when BTstack is initialized. I'm not calling btstack_stdio_init()... so something else, not clear what yet

[ricardoquesada]

The solution for "Arduino Nano ESP32" is to:

• Make sure the "Arduino Nano ESP32" board is selected
• Tools -> USB Mode -> Debug Mode (Hardware CDC)
• and then compile and flash the sketch again

[ricardoquesada]

For other boards, like "Lolin S3 Mini" do:

• Make sure the 'Lolin S3 Mini' is selected
• Tools -> USB CDC On Boot -> Enabled
• and then compile and flash the sketch again

I am trying to run the example on an Adafruit Huzzah32 and I get this compiler error about PINS_COUNT not being define anywhere \Users\ck\Documents\Arduino\libraries\Bluepad32_for_NINA-W10_boards\src\utility\spi_drv.cpp" -o "C:\Users\ck\AppData\Local\Temp\VMBuilds\Bluepad32_ESP32_Gamecontroller_Connection_Test\esp32_featheresp32\Debug\Bluepad32_for_NINA-W10_boards\utility\spi_drv.cpp.o" spi_drv.cpp: In static member function static void SpiDrv::begin()
