I have only module of RN131G with me. I want to use its UART mode with PIC. If i connect only RX, TX, VDD, GND pin connect to the PIC with hand solder. Is it work properly? Thanking you in advance.

The module is NOT 5v tolerant, therefore proper level translation will need to be employed if your PIC is operating at 5v. Also be aware the Sensor pins are only 1.2v inputs and are NOT 3.3v tolerant, while GPIO, TX and RX are all 3.3v tolerant.
