On my previous thread, I got the following message.
"Please note that PUART hardware flow control has some in the current SDK. Our dev team has already fixed the issue, and the fix will be available on the next SDK."
Could I have the information whether the issue is fixed on SDK v2.9?
It seems that Hardware flow is disabled by LPM (ePDS) even if I use SDK v2.9.
Solved! Go to Solution.

Hi,
I believe, the issue is fixed.
May I know on which kit are you testing? If it is CYW920819EVB-02 kit, then please note that the the PUART’s RTS on the USB-Serial chip is not connected to any of the CYW20819 GPIOs. Low power mode should not disable flow control.
Thanks,
-Dheeraj
