No not a peep. I never managed to get mine working. Starting to explore other libraries and other ESP32 / MAX30101 and/or 30102 modules.

I just checked it with an Arduino Micro and this is definitely specific to ESP-32 boards. Not just the Sparkfun board but I just tested it with the ESP32 DEVKITV1....

Actually, Adafruit beat you guys to it: https://github.com/espressif/arduino-esp32/issues/4729 This is why the Sparkfun Max library doesn't work with ESP32 boards.

Yes. The issue is with the compatibility between the ESP32 library and the Sparkfun MAX3010x library. I believe that it can be addressed on either side. It doesn't look like...

@ROdoka I just checked the ESP-32 repository and it looks like they updated some of the i2c core communication code in the last release (hopefully). I'm not sure if it...

@ROdoka Yes, I've had the same experience. This problem is specific to ESP32 and ESP8266.

I have the same problem with both ESP8266 and ESP32. The sensor is never found and the light never comes on, even if you remove the while(1) in the setup.

Any chance that there is an update for this issue?

@VojtechBartoska thank you. If there would be any way to add this to roadmap I would very much appreciate it. Thank you for all your hard work!

@VojtechBartoska In case it is useful, it looks like 2 commits were made in the ESP-IDF since the problem was brought up by @me-no-dev on the ESP-IDF github: https://github.com/ci4rail/esp-idf/commit/6fcb9a53b48a22f4b5980621653d63ae5e7357c1
