[PIC] PIC16F628A and bluetooth UART interface

[adeel.sid]

I am trying to interface PIC628A with WT32i.
PIC has USART interface and WT32 has UART pins.
Knowing that "Synchronous mode (USART) requires both data and a clock and asynchronous mode (UART) requires only data"
I concluded that I have to connect pins 8 and 9 of PIC to respective WT32 pins (16 and 15)
But I am confused WT32 pin#s 20,21 (NRTS and NCTS)

Should I have to use them?
What pins of PIC will be connected to them and why?

Well go through the datasheet of WT32 if it is of UART interface
then cross-connect Rx and Tx pin of both devices with GROUND Common
