ESP32 TTGO Bluetooth Device Scanner

In this project we will learn how to make a Bluetooth Scanner using a ESP32 TTGO to Display the Bluetooth devices around.

• TTGO ESP32
• Some Bluetooth device that you will try to locate like a smart bracelet ,etc
• Visuino program: Download Visuino

The Visuino: https://www.visuino.eu needs to be installed. Start Visuino as shown in the first picture Click on the "Tools" button on the Arduino component (Picture 1) in Visuino When the dialog appears, select "TTGO T-Display ESP32" as shown on Picture 2

• Select TTGO T-Display ESP32 board and in the properties window expand "Modules>Bluetooth LE>Operations
• Click on the Operations 3 Dots
• In the Operations window drag "Search Bluetooth Devices" to the left side and in the properties window set "Active" to true
• Close the Operations window

Select TTGO T-Display ESP32 board and in the properties window expand "Modules>Display>Orientation

• Set Orientation to:goRight

expand "Modules>Display>Text

• Set Size to 2

• Add "Clock Generator" component
• Connect "ClockGenerator1" pin [Out] to "TTGO T-Display ESP32" > Search Devices pin [Scan]
• Connect "TTGO T-Display ESP32" > Search Devices pin [Device Name] to "TTGO T-Display ESP32" > Display pin [In]

In Visuino, at the bottom click on the "Build" Tab, make sure the correct port is selected, then click on the "Compile/Build and Upload" button.

If you power the TTGO ESP32 module it will scan for the Bluetooth devices, once it finds the devices it will display them on the LCD.
