PUART RTS/CTS Hardware Flow Control (con't)

[user_2112781]

Hello,

Per this thread: Re: PUART RTS/CTS Hardware Flow Control

I enabled the flow control using the current pins:

RX = P33

TX = P32

RTS = P1

CTS = P3

But my problem is that when I am receiving on the TAG board, the bytes that are read have weird values (0xFF, 0x7F, 0xF7, ...) but they are not the one I am sending. When the TAG board sends bytes to the computer, I receive the correct bytes.

What could be wrong ?

Hello marmottus,

Which SDK are you using?

Have you tried downloading the new SDK?

WICED Smart SDK 2.2.2 for Windows has been released...

Thanks,

JT

Hi j.t

I'm using the 2.2.1 SDK

I switched off the SW4 switches (number 1, 5,  6, 7 and 😎 and now the output is correct.

I will try the 2.2.2, is there anything new regarding the UART ?

Hello Marmottus,

A few things to try:

1.  Check the voltage levels - Are the 2 devices at the same voltage?

2.  Is sleep disabled?

3. Make sure that the baud rate is the same on both sides - The 0xFF, 0x7F, 0xF7 values are indicative of baud rate issues.

Thanks
