CyBLE013025 PUART RTS/CTS

[NiVa_4337911]

Hi,

Is the following discussion valid for the module CyBLE013025-00?

Need clarification on PUART RTS/CTS flow control support

I checked the schematic and found P3 and P1 are free.

Is there any example to know how to use the flow control?

The flow control is avaliable for this module because it uses QFN32 package. The EZ-Serial FW has already realized the flow control function. You can find it in the EZ-Serial user guide: https://www.cypress.com/file/408286/download

But we don't have a code example for this function. You may refer to the include/Drivers/puart.h for the APIs that enable the flow control and pin assignment.
