Thank you ESP_Sprite for suggestions. I have given external 5V supply to the Module, working perfectly alright.

Hi,
I have tried with Arduino-esp32 SimpleBLE example code. I am able to see ESP32BLE with MAC ADDRESS in nRF Connect Application but, not able to connect. Any suggestions regarding this one.

Thanks in advance.

In 5V point = 3.45V
In 3.3V point = 3.27V

yes, I am using USB. I have tried with different USB cables, no change.
I have also tried with Strapping pins setup given in datasheet, still no change.

Please help.

1. When i tried with Wifiscan example with Arduino-esp32 code library, i feel board is keep on resetting.
I have checked with USB cable, it was working fine.
Output screen was attached below.
Can anyone help me out, what might be the problem with dev board.
