Hi Everyone!
We want to consider UART on our our new PSoC 6 IoT design prototype in order to connect to CY8CKIT-062-BLE PSoC 6 BLE Pioneer Board for debugging. We are wondering whether we need to use only two pins of RX and TX or we need to use CTS and RTS pins too.

Only TX/RX is enough, Actually the on board KitProg3 tool(based on PSoC5LP) is also an USB-UART bridge, it only connect UART TX and RX pin betwwen to PSoC6.

Thanks for your response. Actually on the kit it is mentioned that in addition to RX and TX, CTS and RTS are also connected between PSoC 5 and PSoC 6, and that was the reason I came up with the question.

Meysam,
I checked the kitprog3 firmware, the hardware flow control is enabled for CY8CKIT-062-BLE Kit. You can use only TX/RX pin but yout must make sure P5[2](RTS pin) of PSoC6 output logic 0 always.
