Uart Help

Hi Team,
I need to send data encoded from QR / Datamatrix to esp8266 via UART
So can you please help me what steps to follow which initialization to do .
Right now i have done only this

uart = UART(3, 115200)
uart.init(115200, bits=8, parity=NONE, stop=1)

any extra things to do?

& please also tell how to read uart


Add timeout_char=1000 to the init call please.

For really good uart examples, see the Pixy Emulation script that uses the UART.

UART docs:

Thanks a lot Sir.

Sure I will
