How to use SCI in C2000

Hello,
I am using SCI block in C2000 to transmit AT command to a WIFI module(esp32-C3) and receive response from it. The AT command ends with “\r\n”. I can send each character at a relatively slow speed to ensure that each character is received by the WIFI. But I do not know how to correctly receive each character from WIFI. I know the methods of using FIFO interrupts.
How to transmit string more easily through SCI? Can CSV block do this?How to correctly recieve string? Is there a demo?
I am looking forward to your reply.

Best Regards,
Pauleen

Hi Pauleen,

The SCI and CSV blocks are intended for streaming numeric values across the SCI linkage, mostly for debugging or for gathering data. It won’t easily support sending a fixed string. How long is the AT message?
