If you are interested in checking out how to use the BLE features check this article on ESP32 BLE Server and ESP32 BLE Client Getting started with ESP32 Bluetooth I decided to cover the BLE in separate articles, so here we will use the Classic Serial Bluetooth of ESP32 to toggle an LED using Smart Phone. After a long time of surfing and youtubing I realized that there are lot more thing to understand if you have to work with Bluetooth Low Energy (BLE) using ESP32. Hence, I launched my Arduino IDE and went thorough few example BLE programs, through which I understood nothing. Earlier we have to do a huge workaround with Neil Kolbans Library, but now thanks to this guy’s hard work programming ESP32 with Arduino IDE has become a cake walk. it almost has everything to build IoT projects.Īnd just as any hobbyist would love it, the ESP32 is now officially supported by the Arduino IDE. Also, recently I got myself a new ESP32 DEV kit, these modules has a punch of features like in-built Wi-Fi and Bluetooth, ample ADC and DAC pins, Audio Support, SD Card Support, Deep Sleep Mode etc. Bluetooth modules like HC-05 and HC-06 are easy to set-up and quick to use with Arduino IDE, but they have their own limitation like high power consumption and they operate on the old Bluetooth V2.0.
