I am using ESP32 lolin. For code compilation and flashing using ESP-IDF.

To idf.py make available to the current terminal:

source $HOME/esp/esp-idf/export.sh

To add user in the usergroup to avoid permission error

As, I am using Ubuntu for the development, to connect with the serial port of the ESP32 following command is necessary:

sudo usermod -a -G dialout $USER Then log out and back in.

Config the ESP32

idf.py fullclean
idf.py set-target esp32
idf.py build
idf.py flash

To enable bluetooth:

Goto: idf.py menuconfig

then -> Component config -> Bluetooth -> Enable

Following example is being used to create BLE Server
