ESP32 BLE Beacon Scanner Kit with ESP32 + LED
ESP32 BLE Beacon Scanner Kit — Uncover Hidden Signals and Master BLE Passive Scanning
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
With this kit, you’ll code an ESP32 to sniff Bluetooth Low Energy advertising packets, then display each beacon’s identity (MAC address) and signal strength (RSSI) on a crisp 0.96-inch OLED. It’s a hands-on introduction to the invisible world of BLE — exactly the same technology behind contact tracing, asset trackers, and indoor navigation systems. No prior Bluetooth experience needed; just plug, code, and watch nearby beacons appear in real time.
What You'll Build
A fully functional BLE Beacon Scanner that passively listens for advertising frames from devices like fitness bands, smart tags, and BLE sensors. The OLED screen scrolls live RSSI values and MAC addresses, turning your desk into a wireless monitoring station. You’ll be able to watch signal strength change as you move a beacon closer or farther — a tangible way to understand BLE range and interference.
What You'll Learn
- Set up the ESP32 in Arduino IDE and flash firmware without hassle
- Implement passive BLE scanning using the ESP32's built-in BLEDevice library
- Parse advertising packets to extract device MAC addresses and RSSI values
- Drive an I2C OLED display with the SSD1306 library and format scrolling output

Who This Kit Is For
Students in CBSE Class 8–12 exploring IoT and wireless tech, ATL Tinkering Lab mentors needing a ready-made BLE experiment, and young electronics hobbyists (ages 10+) eager to decode Bluetooth signals. It’s also a practical resource for B.Tech ECE/EEE first-year mini-projects, Smart India Hackathon IoT prototypes, and anyone attending workshops at IIT, NIT, or VIT. If you can follow simple wiring diagrams and copy‑paste code, you can complete this project.
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?
Open the AI build companion from the QR code on the box. It’ll walk you through the exact error you’re facing. If you prefer human help, drop a message on WhatsApp and our team will respond within a few hours.
Can this kit detect my phone or Bluetooth headphones?
It captures BLE advertising packets from most Bluetooth Low Energy devices that are broadcasting, including phones in discoverable mode, beacons, and smart wearables. Classic Bluetooth devices won’t show up unless they also advertise via BLE.
What if the OLED screen stays blank after I upload the code?
Double-check the I2C wiring — SDA and SCL must match the ESP32 pins in the guide. The AI companion has a dedicated troubleshooting flow for display issues, and you can always share a photo on WhatsApp for support.
Can I reuse the ESP32 and OLED for other projects later?
Absolutely. Both the ESP32 and the OLED are standard, reusable components. After finishing this kit, you can reprogram the board for Wi‑Fi controls, web servers, MQTT, or any Arduino-based IoT project.
ESP32 scans for nearby BLE beacons and shows RSSI and MAC addresses on OLED. Teaches BLE passive scanning.
