Baud rate selection for S2C


I am using S2C modules in my project. When I set two module as AT mode in XCTU, I get about 23 kbps throughput at 38400 Baud rate in throughput test. However, when I set baud rate greater than 38400 - 58400 or 115200 -, the throughput test crashes and no packet is transmitted. I don’t understand why the communications crashed at the higher baud rate in AT mode. Is there anyone who tried AT-AT throughput test in XCTU at 58400 or higher baud rates?

Thanks for your help.

For higher baud rate above 19200, use hardware flow control and your issue will get resolved.

For this, while adding module in XCTU, select Flow Type: “Hardware” instead of “None”.
