ESP32 BLE Beacon Scanner Kit with ESP32 + LED ESP32 2
ESP32 BLE Beacon Scanner Kit: Uncover Hidden Bluetooth Devices Around You
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build your own handheld BLE beacon scanner that shows every Bluetooth device in range, from fitness trackers to smart home gadgets. Watch device names and signal strength update live on the bright OLED screen. This project turns you into a wireless detective, revealing the invisible signals all around you.
What You'll Build
A portable BLE scanner that displays nearby Bluetooth Low Energy devices—beacons, wearables, tags—along with their signal strength in dBm. The 0.96-inch OLED instantly shows device names (where advertised) and RSSI values, helping you understand how proximity affects wireless signals. You’ll have a working tool to explore the Internet of Things in your own neighborhood.
What You'll Learn
- How BLE advertising packets work and how ESP32 decodes them
- Programming an OLED display over I2C to show real-time data
- Understanding RSSI values and using them to estimate beacon distance
- Writing Arduino code to scan, filter, and display BLE devices

Who This Kit Is For
This kit is ideal for young makers aged 10+ (with adult guidance for younger ones) who want to see wireless signals in action. CBSE Class 9-10 students working on IT projects, ATL Tinkering Lab innovators, and B.Tech ECE first-year students will find it an engaging introduction to Bluetooth Low Energy. It’s also a great activity for parent-child weekend builds.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to chat with your AI build companion, trained specifically on this project. If you need human help, email or WhatsApp us—we reply within a few hours.
Can I use this kit to find my lost Bluetooth devices?
Yes, the scanner will show BLE beacons in range, but it doesn’t pinpoint exact location. You can use RSSI signal strength to judge how close a device might be.
Do I need a computer to program the ESP32?
Yes, you’ll need a computer (Windows, Mac, or Linux) with the Arduino IDE installed to upload the code. We provide a step-by-step video tutorial that makes setup easy.
Will this kit work with my smartphone’s Bluetooth?
The scanner detects BLE advertising packets, which many smartphones and fitness bands use, but your phone must be actively advertising for it to show up. Most phones will appear when searching for nearby Bluetooth devices.
ESP32 scans for nearby BLE beacons and displays device names and RSSI signal strength on OLED.
