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

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. That could mean migrating your legacy applications to the cloud, refactoring code, improving system architecture, or enhancing performance, security, and accessibility.
Put simply: you're keeping what works, fixing what doesn’t, and making your product future-proof.
2. When your digital product is screaming for modernization
Every modernization journey is different, but most start with a few common triggers:
- Security risks: Legacy systems are more vulnerable to threats. Modern platforms offer better encryption, authentication, and compliance features by default.
- Cloud readiness: Moving to the cloud improves scalability and reduces infrastructure costs. A clear application migration to cloud strategy is key for long-term flexibility.
- Performance issues: Slow loading times, crashes, or poor integrations can frustrate users and employees alike.
- Poor accessibility: Older systems often fail to meet current accessibility standards. That’s a problem for both usability and compliance (think: European Accessibility Act).
- Developer roadblocks: Legacy code is harder to maintain and doesn’t attract modern tech talent.
- Business agility: Want to innovate faster? You'll need a flexible, modular system that supports fast iterations and new features.
-
3. Which application modernization fits your needs
There’s no one-size-fits-all approach. The best Application Modernization strategy depends on your goals, existing tech stack, and available resources. Here are a few common Application Modernization approaches:
- Rehosting ("lift and shift"): Moving your app to the cloud without major changes.
- Replatforming: Making minimal changes to optimize for the cloud environment.
- Redesigning: Rethinking the user experience to meet today’s design standards and accessibility requirements. This often includes updating user flows, interface design, and ensuring compliance with regulations like the European Accessibility Act.
- Refactoring: Rewriting parts of the code to improve performance or architecture.
- Rebuilding: Creating a new version of the app from scratch while preserving core functionalities.
- Replacing: Retiring the old app and replacing it with a commercial or custom-built solution.
Choosing the right path often starts with an Application Modernization assessment to map out your system’s current state and identify pain points.
4. From legacy to leading: the modernization process
Most modernization journeys follow a structured path, also known as the Application Modernization framework. At icapps, we guide clients through each stage:
- Assessment & discovery
Understand the current system’s functionality, dependencies, and limitations. - Strategy definition
Choose the right legacy Application Modernization strategy based on business needs and technical feasibility. - Execution
Use the right mix of Application Modernization tools, techniques, and best practices to modernize, whether that means a full rebuild or a phased approach. - Deployment & scaling
Launch the new version, monitor performance, and iterate based on user feedback. -
5. Enterprise Application Modernization: more than just a tech update
For larger businesses, enterprise Application Modernization is often about aligning digital tools with internal workflows, customer journeys, and compliance needs. Think GDPR, ESG reporting, or seamless integrations between tools. The result? Greater agility and competitive advantage.
Needless to say, cloud Application Modernization plays a major role here. A smart cloud migration can significantly reduce costs, enable scalability, and simplify disaster recovery.
6. Legacy software doesn’t have to mean outdated
You’ve probably heard terms like legacy app modernization, legacy system modernization, or legacy modernization services. All of these fall under the umbrella of software modernization, which is the process of transforming outdated systems into modern digital experiences.
And no, that doesn’t mean throwing everything away. In many cases, legacy Application Modernization preserves the core business logic while improving security, performance, and maintainability.

European hosting providers: Why companies are moving away from US cloud
How do US regulations impact your business data sovereignty in the EU?
In today's tense geopolitical landscape, an increasing number of organizations are asking themselves this exact question. For European businesses, European hosting providers are quickly becoming the go-to alternative to major US-based cloud providers.
And that’s not without reason.
Stronger privacy laws, better protection
Let’s start with the facts. The US CLOUD Act gives the American government the power to access any data managed by a US company, no matter where that data is stored. Even if your servers are located in Europe, they’re not safe from US jurisdiction if they’re managed by a US-based provider.
That doesn’t sit well with businesses that want to give their users real data protection. Especially with strict European privacy regulations like GDPR in place, trust and transparency are key.
Why we believe in European alternatives
At icapps, we’ve been actively researching European hosting providers that align with our values. Scaleway and OVHCloud are two strong examples that put privacy and sovereignty first. These providers are built on European soil, operate under EU laws, and are more transparent about how they handle data.
Some projects like Gaia-X even try to take things further by creating a European framework for cloud infrastructure. While some US tech giants are involved in these projects too, that doesn’t always mean bad news. What matters is having clear, enforceable rules, and Europe is currently ahead on that front.
Curious which providers we’re considering? We’ll reveal more in the next post.
Can encryption solve the problem?
You might wonder: what about encrypting all data? That’s definitely an option, and one we sometimes recommend. But keep in mind that, with the 'harvest now, decrypt later' mindset, it’s important to find the right balances, strong encryption is key, but it shouldn’t slow down real-time services unnecessarily.
The ideal scenario? Storing your data with a provider who already respects your need for privacy, without extra workarounds.
This isn't just about compliance. It’s about trust.
Whether you’re building a mobile app, managing health data, or processing payments, your users expect privacy by default. And let’s face it: telling them their data is safe within the EU is a much stronger message than “hosted somewhere in the cloud.”
European hosting gives you that peace of mind.
Is your business truly protected under EU jurisdiction?
As Belgian companies navigate evolving privacy laws and the complexities of international data access, European alternatives have matured into powerful, high-performance solutions. Use this checklist to evaluate your current "Cloud Sovereignty" score and discover if a move to a local provider is your next best move.

This blog is the first in a series. We’ll be sharing:
- How we select European alternatives (and which ones made our shortlist)
- An interactive questionnaire to help you decide if you should switch
- The steps we’ve taken as icapps to transition our own stack

6 questions you probably have about the European Accessibility Act (and the answers you need)
What exactly is the EU Accessibility Act?
The EU Accessibility Act is a European directive designed to ensure that digital products and services are accessible to everyone, including people with disabilities. This includes websites, apps, self-service kiosks, e-readers, ticketing systems, and even e-commerce platforms.
Starting in June 2025, private sector companies must comply. The directive is implemented through national legislation, including in Belgium. The goal? Guarantee accessibility for all users, regardless of their abilities.
Who does this legislation apply to?
The EAA applies to companies that offer digital products or services on the European market. This includes banks, telecom providers, e-commerce companies, and developers of software and digital platforms.
SMEs with fewer than 10 employees and an annual turnover under €2 million are exempt. Still, it’s worthwhile for every business to improve digital accessibility, not just for inclusivity, but also for customer satisfaction and conversion rates.
What do you need to do to be EAA-compliant?
To be compliant, your digital products must meet WCAG 2.2 standards (Web Content Accessibility Guidelines). These guidelines are based on four key principles:
- Perceivable
- Operable
- Understandable
- Robust
A great way to start is with an Accessibility Audit.
How do I know if my product meets the standards?
Start with a Quick Scan. It will give you immediate insight into your biggest pain points, and where you can make quick wins.
What are the benefits of accessible products?
Accessible digital products offer many advantages:
- Larger audience: Reach people with disabilities, older users, or those with temporary limitations (like a broken arm).
- Better SEO: Structure, contrast, and clear navigation help search engines too.
- Higher conversion rates: Accessible UX is usually better for all users.
- Legal security: Avoid fines and legal risks.
How do I get started?
The first step is understanding where you currently stand. Then, create a roadmap to full accessibility compliance by June 2025.
Not sure if the EAA applies to you?
European Accessibility Act: What it means for your business and how to comply
What is the European Accessibility Act (EAA)?
The European Accessibility Act is a directive that requires companies to make certain digital and physical services accessible for people with disabilities. This includes:
- Online shops and e-commerce platforms
- Banking apps and ATMs
- Public transport services (air, rail, bus, boat)
- Digital communication tools
- Streaming platforms, TV, and e-books
- Emergency service tools
If you operate in one of these sectors, your business must meet accessibility requirements by June 2025.
5 steps to comply with the European Accessibility Act
Making your services compliant may feel overwhelming, but these 5 steps will help you get started:
1. Apply the European Accessibility Standard (EN 301 549)
This standard outlines accessibility requirements for ICT products and services. It’s based on the WCAG 2.1 guidelines — which many digital teams are already familiar with.
2. Audit your digital products
Run a full accessibility audit on your website, app, or digital platform. This helps you identify gaps and prioritize what to improve.
3. Publish an accessibility statement
Every business must create an accessibility statement that explains how its services meet the legal standards.
4. Train your team on accessibility
Everyone involved in creating digital products — from developers to designers to content creators — should understand accessibility principles. Organize regular training sessions to keep your team up to date.
5. Make accessibility a long-term habit
Accessibility is never “done.” Regularly test your platforms, gather user feedback, and improve continuously. Embed accessibility into your workflows and development cycles.
Why digital accessibility is good for business
Meeting the EAA requirements isn't just a legal necessity — it's also a wise business decision.
- Avoid legal risk: Fines and legal consequences are real if you don’t comply.
- Reach more users: Over 1 in 6 people worldwide has a disability. Accessibility expands your market.
- Boost your brand: Inclusive products demonstrate innovation, responsibility, and care.
