Hello,
We have been using CYUSB3014-BZXI and EZ-USB FX3 SDK 1.0 version.
The problem is it takes long time (about 250msec) in function CyU3PUartTransmitBytes.
We send 7Bytes, it takes more than 250msec. I think the time is derived from the wait time in CyU3PUartTransmitBytes before actually sending UART.
How to improve the UART transfer speed?
Thanks for your quick response in advance.
Regards,
KJ

Hi KJ,
It is recommended to use the latest FX3 SDK 1.3.4.
Please refer to this KBA on optimizing the code size:

Also could you share your firmware project with us?
Best Regards,
