  Hello, I have a problem with the ESP8266 Audio library, it works fine but when I try to run the command **ledcWrite(ledChannel,6)** to activate a servo, the ESP8266 Audio library stops working. It is exactly the red box in the image

  @holofloh good call, but if the // are removed then the ledc commands are “before” the open curly brackets { of the next line, so I am still confused!

  The ENV-Sensor does not give me readings if it exceeds a distance of 20cm in the grove cable, how can I solve it?

  Hello @jesus-valencia which M5Stack device (Fire, Base, Core2, Stick, Atom, ...) are you using? I am asking because I've tried with M5StickC Plus, M5Stack Base and M5Atom Lite and 2 m of cable between M5Stack device and ENV sensor and it worked just fine. (Note: I used UIFlow for this test.) Care to share your code? have you measured the voltage on the ENV sensor? (Maybe the voltage is ok?) since you have multiple ENV sensors, do all of them fail? (Maybe one is faulty?) have you tried a different power source? (Maybe the USB power supply is weak?) have you tried a different USB cable? (Maybe the USB cable is bad or too long?) Thanks Felix

  @M5Stack After looking at your comment again I figured out what you were trying to tell me (Took me a while to figure it out). I forgot to tell the M5Stack where to look for the text file using /sd/file_name. That took care of the error. Still am unable to print what I want to the screen but at least I'm one step closer.

  Hello @Johnny241 Yes, from what I am reading Ethernet seems to be a bit tricky. I assume you were able to flash and run the Arduino Modbus WiFi example, correct? If so, I'd continue with a simple Ethernet example (not Modbus related) to get familiar with Ethernet and the LAN module. Only then I'd try to modify the Arduino Modbus WiFi example and replace WiFi with Ethernet. Felix

  Hi @rohitpatil I'm afraid our products are only using OV7740 and OV2640so I doubt we can help you, perhaps try the esp32 forum on reddit
