CTS RTS

Hi,all.

In dsps project "DA14580_DSPS_3.150.2" ,perpheral device.

UART_HW_FLOW_ENABLED opened.

set like this.

#define CFG_UART_HW_FLOW_CTRL
# undef CFG_UART_SW_FLOW_CTRL

#define CFG_EXT_SLEEP
#undef CFG_DEEP_SLEEP

When connected,but also lose data Frequently,sometimes get data,sometimes are not.
Why,and how to handler this problem.

thanks.
