When Bluetooth devices compete: how we solve multi-device BLE challenges
The challenge most apps underestimate
Once the platform scaled, new needs emerged:
- Reliable location detection: To ensure users could always end their rides, even in GPS-poor environments like underground stations, we implemented Beacon technology as a vital fallback.
- Maintenance access: Service teams needed dedicated BLE access to battery locks for maintenance purposes.
Suddenly, the app wasn’t talking to one device anymore. It was juggling multiple Bluetooth interactions at the same time.
And that’s where things started to break.
One BLE radio, multiple demands
Smartphones only have one Bluetooth radio. Yet many apps treat it like an unlimited resource.
In practice, this leads to:
- Silent scan interruptions (especially on Android)
- Features interfering with each other
- Device-specific bugs that are hard to reproduce
- “Works most of the time” experiences that frustrate users
For platforms like Blue-bike, this directly impacts both user experience and operations. To solve this, we leveraged our partnership to build a robust architecture that treats Bluetooth as a shared system resource.
Our approach: treat BLE as a shared resource
At icapps, we’ve seen this pattern before across multiple projects. When apps evolve, Bluetooth complexity grows with them.
Instead of patching issues later, we design for it upfront.
The key insight is simple: Bluetooth should be managed like any shared system resource.
Meaning: just as a processor decides which app gets processing power, there needs to be a system that determines which function is allowed to use the Bluetooth antenna at any given moment. Without this central management, different parts of the app (such as unlocking the lock versus searching for beacons) will compete with each other for the connection, leading to failed actions and a frustrated user.
The solution: a scan coordinator
To prevent conflicts between BLE features, we implemented a centralized scan coordinator.
In short, it:
- Controls who can scan at any given time
- Assigns priorities (user actions over background processes)
- Temporarily pauses lower-priority scans
- Applies rate limiting to avoid OS restrictions
- Ensures consistent behavior across devices
This creates a predictable and stable Bluetooth layer, even as new features are added.
Why this matters for your product
If your app connects to just one device, you might never notice this problem.
But if you’re building:
- A connected product ecosystem
- A mobility or IoT platform
- A feature roadmap with future integrations
…this challenge will surface sooner or later.
And when it does, it won’t show up in testing. It will show up in production.
Designing for scale from day one
What we built for Blue-bike is not a workaround. It’s a scalable foundation.
By centralizing BLE coordination:
- User interactions become reliable
- Background processes stay invisible but effective
- New integrations don’t introduce new risks
Most importantly, it allows teams to keep innovating without breaking existing functionality.
What this says about how we work
This project reflects how we approach digital products at icapps.
We don’t just build what’s needed today.
We anticipate what your product will need tomorrow.
Because in connected ecosystems, small technical decisions can have a big impact on user experience.
If you’re working on a product with Bluetooth, IoT or multiple device integrations, it’s worth asking: Are we building for today’s use case… or tomorrow’s complexity?
FAQ: Bluetooth and multi-device BLE
What is multi-device BLE?
It refers to apps interacting with multiple Bluetooth Low Energy devices, common in IoT, mobility, and connected products.
Why does Bluetooth fail with multiple devices?
Because smartphones only have one BLE radio. Multiple scans or connections can interfere, causing unreliable behavior.
How do you manage multiple BLE interactions?
By using a centralized approach, like a scan coordinator, to control access, prioritize actions, and prevent conflicts.
What are common BLE issues in mobile apps?
Unstable connections, background limitations, Android restrictions, and conflicts between multiple Bluetooth processes.
When do you need a scan coordinator?
As soon as your app connects to multiple devices or combines background and foreground BLE features

The outcome will guide your Application Modernization strategy, ensuring you're not just chasing trends but making informed, scalable decisions.
Modernization approaches tailored to your product
There’s no one-size-fits-all path to modernization, but it always starts with an evaluation. This crucial first step helps us align on where your investments will make the most impact. From there, depending on your goals and available resources, you can choose from several Application Modernization approaches, such as:
- Rehosting: Move your app to the Cloud without changing its code
- Refactoring: Clean up and reorganize your code for better performance
- Replatforming: Make minimal changes to your app to take advantage of Cloud capabilities
- Rearchitecting: Redesign the architecture to support AI or microservices
- Rebuilding: Recreate the app with a modern tech stack
For legacy systems, legacy Application Modernization strategies focus on minimizing disruption while upgrading functionality. Many companies also rely on legacy modernization services to support this transition.
Cloud migration as a stepping stone to AI
AI and Cloud go hand in hand. Whether you’re exploring Cloud Application Modernization or developing a full application migration to cloud strategy, this move sets the stage for smart, scalable solutions.
Cloud environments provide:
- On-demand compute power for training AI models

How AI can change the way we detect asbestos
The problem: Time-consuming and error-prone inspections
Asbestos inspections typically require extensive manual work. Inspectors must visually examine materials, take notes by hand, and write detailed reports. This process is slow, increases the chance of human error, and can delay important decisions.
The solution: AI-powered automation
By using AI, we can automate many steps of the inspection process. This means less manual work, fewer errors, and faster results. Inspectors can focus on their job while AI helps streamline their tasks.
What makes this AI solution unique?
We’ve combined AI-powered detection with speech-to-text technology to make asbestos inspections smarter and more efficient. Here’s how:
- Voice input instead of notes: Inspectors can simply speak their observations instead of writing everything down. AI-powered speech-to-text technology (like OpenAI’s Whisper) converts spoken words into structured text, ensuring no essential details are lost.
- Automated image analysis: Traditional asbestos identification relies on human observation, which can be inconsistent. Our AI analyzes images taken during inspections, quickly identifying possible asbestos-containing materials with greater accuracy.
Less paperwork, more productivity
Writing detailed inspection reports can be time-consuming, often taking longer than the actual inspections themselves. Our AI-powered system automatically generates reports based on recorded voice notes and captured images, saving inspectors valuable time and reducing the chance of errors.
Smarter image analysis for better detection
Detecting asbestos isn’t always straightforward. It requires careful materials analysis; human judgment alone isn’t always enough. Our AI-powered image classification technology scans photos taken during inspections and flags potential asbestos-containing materials. We plan to refine this technology even further in the future, making inspections even more reliable.
A game-changer for asbestos inspections
Traditional methods are slow and prone to mistakes, but our AI-powered solution streamlines the entire process. This technology has the potential to revolutionize asbestos detection and other types of inspections requiring strict safety and compliance checks.
What’s next?
We’ve proven that AI can make asbestos detection more efficient, but this is just the beginning. Our next steps include:
- Improving AI-powered image recognition to enhance detection accuracy.
- Expanding the capabilities of AI-driven report generation.
- Developing a fully market-ready solution that can be used across industries.
Conclusion: The future of asbestos inspections is AI-driven
With AI-powered speech-to-text, automated reports, and smart image analysis, we’re creating a future where asbestos inspections are quicker, safer, and more reliable.
6 signs your digital product is ready for modernization
Whether you're dealing with a decades-old system or simply struggling to scale your current solution, legacy software modernization is becoming a critical part of every organization's digital strategy. But what does that actually involve? And why is now the right time to consider it?
Let’s break it down.
1. What is Application Modernization?
At its core, application modernization means updating your existing software systems to better align with current business needs, user expectations, and technology standards.
