About making ESP32 as BLE host/master

[kcmikelo]

hi guys:
I am very new to ESP32 Arduino. I have two questions.
1. If I want to program my ESP32 with Arduino IDE which programmer should I choose?

2. Is there any Arduino library for making ESP32 a BLE Master device?

The programmer sub-menu is not used at all when ESP32 device is selected, only the serial port sub-menu is relevant.
