BLE (Bluetooth Low Energy) technology allows mobile apps to discover and connect with nearby devices without using much battery. If you want to create a popup-style animation or alert that appears on surrounding phones using a BLE scanner app, here’s how you can approach it.
Join WhatsApp GroupWhat is BLE Scanner?
BLE Scanner is a tool that scans and interacts with nearby BLE-enabled devices. These apps (like “BLE Scanner” on Android or iOS) let you:
- Discover nearby Bluetooth Low Energy devices
- View their signal strength (RSSI), UUID, services, and characteristics
- Send and receive data between devices
Step-by-Step to Trigger Popup Animation on Surrounding Phones
1. Install a BLE Scanner App
Download a BLE scanner app from the Play Store or App Store. Popular choices include:
- BLE Scanner by Bluepixel Technologies
- nRF Connect by Nordic Semiconductor
2. Enable Bluetooth on All Devices
Make sure Bluetooth is turned on for both the sender (your phone) and any nearby receiving phones.
3. Configure Your Device as a BLE Peripheral (Broadcaster)
You’ll need a mobile app that can broadcast a BLE signal (your phone acting as a beacon). This device will advertise data (like a UUID or custom message) to nearby scanners.
You may need a separate app for this if the BLE Scanner you’re using only scans. Try apps like:
- Beacon Simulator (Android)
- LightBlue (iOS)
4. Design the Animation Trigger
When nearby devices detect your BLE signal (based on UUID or service ID), they can trigger a popup animation within their own app.
Important: This requires that those phones are running an app (your custom app or a shared one) that listens for that specific BLE broadcast and triggers a UI animation on detection.
5. Use Custom App Logic
To make it truly automatic, you’d need a custom-built app on nearby phones that:
- Scans for your BLE broadcast
- Recognizes the beacon UUID or custom data
- Triggers a local popup animation (like a notification or an animated card)
Final Thoughts
BLE Scanner apps help detect and test Bluetooth broadcasts, but to display popup-style animations on surrounding phones, you’ll need:
- A phone broadcasting via BLE
- A companion app on target phones that reacts to the broadcast
It’s a powerful toolset for interactive experiences, smart advertising, or localized engagement.
