LAUNCHXL-CC26X2R1: Menu not displaying

Part Number: LAUNCHXL-CC26X2R1

Tool/software:

I am using Launch-XL CC2652R1 board for bluetooth communication. During debugging and flashing of the Simple_central example code, Gaat_Read and Gatt_write commands are not displaying in the terminal menu. Can you please help me find what is the mistake.

Thank you.
