'UART' object has no attribute 'readall' with the latest firmware

[Wooopz]

Hello,
I just upgrade the firmware of my wipy 3 to Pycom MicroPython 1.20.2.rc6
and now i have the error : 'UART' object has no attribute 'readall'

Wipy3 with most recent firmware.
uart.readall()
returns AttributeError: 'UART' object has no attribute 'readall'

This is pretty crazy, since it is a documented function that has always been supported: https://docs.pycom.io/firmwareapi/pycom/machine/uart.html

readall is used into serial.py .
what can i do to bypass this error please ?
thanks.

Hello,
While facing the same error, i downgraded the firmware of my WiPy to version 1.18.1 and this seems to work.
BUT...this is only a temporary solution as the problem resides in the serial library.
This workaround comes from this post : https://forum.pycom.io/topic/3127/clearing-uart-buffers/7
Using the latest stable firmware, i can confirm that using uart.read() instead of uart.readall(), does not work.
It would be very nice if someone with experience in these matters would fix this.

Hi, I can confirm that using uart.read() instead of uart.readall() DOES work. Tested on FiPy version 1.20.2.r1

The workaround suggested in this post in the pycom forum
