UART READ WRITE

[DDA]

I am running the following code portion on a Fipy and LoPy with firmware version 1.18.1.r7.

uart1 = UART(1, baudrate=9600)
uart1.init(9600,bits=8,parity=None, stop=1)
rcv=False
while True:
        while not rcv:
            time.sleep(5)
            if uart1.any() > 0:
              recv=uart1.readall() 
              print('Received from PIC %s' %recv)
              rcv=True

The serial communication is between a PIC 18F4620 processor and Pycom via a level logic convertor ( TXS0108EPWR from Texas Instruments). The code is working as expected on the LoPy but the same code on FiPy has buffer issue. I keep getting the same old data from the buffer for FiPy. Tried uart.deinit() as well but no success. Why is the UART buffer acting differently between LoPy and Fipy?

Hi @robert-hh ,
Both Lopy and Fipy have firmware release='1.18.2.r1'

[robert-hh]

@dda Do both device have the same firmware version?
