picocom on linux mint

Picocom works fine with ESP8266 and ESP32 boards here on CentOS 7. Is your user a member of the dialout group?

YES

Unfortunately this is just how the ESP8266 works. It has a bootloader which writes a bunch of info out to the serial port, but at a different baud rate (74880, instead of the 115200 that MicroPython uses). Because your serial console is at 115200, the 74880 bits look like garbage. So if you change ...

The garbage is normal and no sign of an error. After reset, the first messages of the boot loader are send with 76800 baud. Received at 115200 baud, that looks like garbage. So nothing is broken. You just did not see that before. And yes. This ENOENT message just says: file not found. In this case:...

You can set the pin value with either: pin.value(1) resp. pin.value(0) or shorthand: pin(1) or pin(0) For any question on usage, please refer the documentation: http://docs.micropython.org/en/latest/ There are quick examples for each module type, e.g. ESP8266 and Pin: http://docs.micropython.org/en...
