You have to detach REPL on UARFT first, with import uos uos.dupterm(None, 1) See: http://docs.micropython.org/en/latest/esp8266/quickref.html Thanks. Tried that as well. Still seem to hang on the sensor handshake. Moved back to my C code :( WebREPL connected >>> from pyfingerprint import PyFingerpr...

UART0 is fix assigned to the pins denoted as TX and RX. So do not have and cannot assign pins to it. It’s seems to mess up with webrepl and hangs after the call to the sensor. Sadly, reverting back to non-python, with software serial :( I really wish a serial port emulation is implemented soon. I s...

@rave The lib you are trying to use is made for ESP32. Lacking a second UART, it will not work this way on a ESP8266. Using webrepl for the micropython prompt, you couls use UART0 for that purpose.

And how do I do use UART0? Just emit the pins?

FWIW, this is not a "software" UART (there's no soft UARTs in MicroPython), and there's only one full hardware UART on the ESP8266 (which is also used for the REPL). That's disappointing :) If this is the case, why do I need to declare the pins? Isn't it board depandant? The tx and rx kwargs need t...

Hi, I'm trying to test https://github.com/chrisb2/micropython-fingerprint on my esp8266 and following the instructions, I fail to init the software UART: from pyfingerprint import PyFingerprint from machine import UART sensorSerial = UART(1) sensorSerial.init(57600, bits=8, parity=None, stop=1, rx=1...
