UART buffer flush

[SameerChouksey]

Hello,

l am using below code to wait for the UART data and take action accordingly. It works for the first time but once I receive some data uart.any() is always true after that. The uart buffer doesn't get clear it seems. Please check.

while(1):
if uart.any():
data = uart.readall()
print("data received over UART:"+str(data))
s.setblocking(True)
print(s.send(data))
time.sleep(0.5)
del data

Objective is to send data only when there is a new data available over uart.

Regards,
Sameer

Hi,

Yes, it seems to be the same issue. When can I expect a fix for this?

Any work around? any other api to check new data arrival at UART?
