Hi everyone, right now I have a project where I cant debug if everything is correct because I cant read the serial output of a ESP8266. My other topic for this project: I2c multiple devices not recognized I connected the ESP to multiple Arduino Nanos via a bi-directional level converter (3,3V/5V)…

It's for this project: GitHub - ricaun/DuinoCoinI2C: This project design to mine Duino-Coin using an Esp8266 as a master and Arduino as a slave. I solved the problem: the FTDI adapter which I tried to use to read the TX pin was not grounded...
