IoT Testing Services
TechMagic’s IoT testing services cover the software side of a connected product before it reaches customers. We test Bluetooth Low Energy (BLE) pairing and reconnection, run the companion app across a real device matrix, load-test the cloud telemetry, and put everything above the device through CREST-accredited security testing. Our senior QA and security engineers run the testing, so you do not have to hire your own.

The Challenges We Help You Solve
The problems that reach customers start in software: pairing, the companion app, security, telemetry, compliance, and reporting. Each one below comes with how TechMagic handles it.
Hiring a QA function takes months, and a release date rarely waits. Our QA engineers run functional testing and compatibility testing on a real device matrix built for your release.
A vulnerability found by a customer is a different conversation from one found in testing. TechMagic’s CREST-accredited testers run security testing on the mobile apps, API, and cloud, where most data breaches on connected products start.
Lab conditions rarely match real interference, distance, and half-empty batteries. We test BLE pairing and reconnection against the network conditions your product will actually meet.
Retrofitting audit-readiness two weeks before a deadline is slower and riskier than building it in. TechMagic tests for it from the first release, while ensuring compliance stays your auditor’s call.
Ten devices in a demo say nothing about ten thousand in the field. We put telemetry under realistic device counts, since data generation follows the exponential growth in units sold.
Shipping without a real report means shipping on hope. Our engineers hand back a written report of what passed and what still needs fixing, so informed decisions rest on accurate results.
IoT Testing Services We Provide
Our IoT software testing services cover the whole surface of a connected product: connectivity, the companion app, cloud telemetry, security, field behavior, and release automation. None of it touches the physical device.
AI-Ready Products, Tested by Certified AI/ML Pentesters
When a connected product adds a model, the test surface grows with it, so we test the new paths alongside the rest of the stack.
The Business Value of IoT Testing
Testing changes what ships, how quickly the next release follows, what you can prove about security, and how much guesswork is left at go-live.
Rigorous testing of IoT devices keeps failures inside the build, where a fix is cheap. The same failure in a customer’s hands costs a support queue, a replacement, and a review that stays up for years.
A growing product slows its own release cadence, because manual regression grows with it. Our engineers build an automation layer that keeps the testing process flat, so operational efficiency holds and you reach the market faster.
A security claim is only worth what someone can verify. TechMagic holds CREST accreditation and works to ISO 27001 and SOC 2, which also govern how your data privacy is handled. Findings come to you, and compliance stays with your auditor.
Someone always asks what has been tested, and vague assurance does not survive the question. We write coverage down layer by layer, so the answer is a document you can hand over.
Customer Stories & Clutch Reviews
CEO, Bamboo
TechMagic supports ongoing development and DevOps for an investment platform, ensuring stable feature delivery. "We were impressed with their Strang System, team management processes, and overall composition."
CEO, Innovations Now
They’re very thorough, and that’s part of their DNA.
Founder, Taggis
TechMagic is different because they’re eager to make sure that we’re content with their services. They’ve even come to check-in with our team in Sweden a few times. We’re very close in terms of our business relationship. I would also like to add that their pricing level is good, and they always respond quickly.
Co-Founder & CTO, Governance.com
They worked very quickly. Within a week, they delivered visuals that I wasn’t expecting for several more weeks.
CTO, engin sciences
"TechMagic is very good at picking up what needs to be done to move the project forward."
COO, PeerPilot
They did an impressive job of understanding where we wanted to go without us having to explain it explicitly.
Cases You Might Be Interested In
The connected fire-safety hub lets facility teams monitor the fire-alarm panel remotely. They can also control it from a mobile app. The app integrates with addressable detectors. It also connects to an open BMS platform. This is part of a certified manufacturer's shift toward unified smart-building technology.
The app delivers a year-long AI-powered training program with guided workout animations for proper form, mood and heart-rate tracking for personalized insights, and integration with Garmin, SUUNTO, Motorola, and ANT+ devices for fitness, therapy, and rehab use cases.
Our team built the iOS and Android apps powering Scoozer's rental flow: BLE scan-to-unlock, phone-as-key start and stop, and a return flow enforcing venue rules. The platform now runs live across multiple US mall locations, including Simon and Premium Outlets.
For this case, we leveraged IoT technology to create learning solutions for kids. The infinibook is a screen-free reading device. It pairs with a companion app for local and remote audio recording. Parents can swap in different story booklets. The app also includes Montessori-inspired games. Distant relatives can narrate stories remotely through the app. This helps children build early literacy skills without a screen.
We built VitalsBridge's Android and iOS apps, migrated the embedded stack from Windows IoT Core to Linux, and moved device communication from Bluetooth Classic to BLE, improving reliability. The product was later acquired by Laerdal Medical in March 2026.

We map the device, app, cloud, and security surface that needs coverage, then agree what “tested” means for this release. You get test plans and a scope before anyone writes a single case.
Next, our engineers build the device matrix, the testing environments, and the automation behind them. The shape of all three follows your IoT systems and your release cadence.
Once the environments are live, TechMagic runs functional, compatibility, and security passes in parallel and reports findings as they land. Our testing covers the whole path a signal takes: pairing, transport, cloud, and the dashboard an operator reads.
Finally, we verify the fixes and keep the pipeline running for every release that follows. A successful deployment is the one you can repeat next month without re-staffing the work.
Tools and Tech Stack
Every connected product we test has a device layer, a transport layer, and a cloud layer. These are the IoT testing tools behind each one: - BLE for device connectivity: pairing, range, reconnection, and how the app recovers when the link drops. - Kotlin Multiplatform for the companion app: one codebase, tested against a real matrix of iOS and Android devices. - AWS IoT Core for the cloud layer: ingestion, device registry, and the telemetry path behind the entire ecosystem. - CREST-accredited security testing for everything running above the device, with ISO 27001 and SOC 2 practices shaping how your data is handled.
What the Customer Says About Working With Us
Axel Vanraes — tech co-founder at Tiro.health
Adrian King highlights TechMagic's team dedication and the strong early user enthusiasm for the product we're building together.
Samar Birwadker highlights TechMagic’s reliability and wide expertise in working on complex AI-native products.
Ask what we would test and the answer names the stack: BLE pairing behavior, Kotlin Multiplatform builds, AWS IoT telemetry, and the API surface underneath. Our IoT testing experts cover the software layer of the entire IoT ecosystem: the pairing handshake, the app, and the cloud behind both.
Testing runs alongside the build, so findings arrive while there is still time to act on them. The same engineers stay on as scope moves, and nothing gets re-explained at the next milestone.
