ESP32 Blynk 2.0 | ESP32 Bluetooth Relay Control

#ESP32 #Blynk #Bluetooth
This is second part of my video series of esp32 Blynk relay control. and In this video I will show you how to add the Bluetooth feature in the project for controlling the home appliances. I am using the built-in Bluetooth of ESP32. That is called BLE (Bluetooth Low Energy). for Bluetooth control, I have created the Android App using MIT App Inventor. In this video, I will show you how to setup, and install android App for Bluetooth.

In Part 1 of ESP32 Blynk 2.0 | ESP32 Bluetooth Relay Control video, I have discussed about how to control home appliances using new Blynk over the internet and using manual switches (Push Buttons) without internet. So, I have upgrade the project and add the Bluetooth feature as well.

I am using ESP32 Development Kit Version 1, but if you select the board as "DOIT ESP32 DEVKIT V1" from Arduino IDE, and then compile the code. you will definitely get the following error. ERROR: "text section exceeds available space in board". This is because the sketch is bigger than the available flash memory of ESP32. You can remove then"ESP32 program size" error by changing Esp32 partition size. this is how Esp32 out of memory issue will solve.

Steps to Solve ESP32 Sketch Too Big Error
On Arduino IDE,
STEP 1: Navigate to Tools - Boards - ESP32 Arduino. Then select the "ESP32 Dev Module".
STEP 2: Navigate to Tools - Partition Scheme. Then select the option "Minimal SPIFFS (Large APPS with OTA)" or "No OTA (Large APP)" option.
