💡 Takeaways
Connected medical care is no longer a trend. It’s an expectation. From the market and patients.
Bluetooth modules are integrated into almost all medical devices, like smart blood pressure monitors or continuous glucose sensors. Why? Because it’s one of the most affordable, low-power, and mobile-friendly connectivity options.
And while the idea of Bluetooth medical devices is clear, their integration with healthcare apps still raises many questions and concerns.
Medical devices should work reliably across iOS and Android, maintain strong connectivity in hospital and home environments, and meet all regulatory requirements (FDA, HIPAA, GDPR, you name it).
At the same time, you have pressure to launch faster, validate MVP, and deliver a smooth mobile experience without compromising on compliance or quality.
In this guide, we’ll discuss:
So, let’s start with the basics of Bluetooth connectivity in the healthcare industry!
Not all Bluetooth technologies are created equal. And in healthcare app development, choosing the right protocol is one of the most important technical decisions.
Bluetooth Classic is used for constant, high-throughput data streaming (think about your wireless headphones). Meanwhile, BLE (Bluetooth Low Energy) is optimized for periodic data bursts and low power consumption. And that’s exactly what most connected medical devices need.
Let’s compare BLE vs Bluetooth for wireless medical devices:
Specification | BLE | Bluetooth Classic |
---|---|---|
Energy Consumption | Ultra-low (ideal for battery-powered devices) | High (designed for continuous use) |
Data Transfer Rate | ~250 kbps (more than enough for vital sign monitoring) | Up to 3 Mbps |
Range | Up to 100 meters (with Bluetooth 5.0+) | Up to 10 meters |
Connection Model | Asynchronous, event-driven | Continuous streaming |
For most medical devices, whether you're building a wearable ECG patch, a smart inhaler, or a home-use blood pressure monitor, BLE offers the best balance between power efficiency, latency, and mobile integration.

Want to turn BLE connectivity into your killer feature?
Let’s talk!
When building a clinical-grade app, getting Bluetooth to “just work” isn’t as simple as turning on a module. There’s a lot going on under the hood and selecting the right protocols early on can make or break your app’s performance, power efficiency, and long-term scalability.
According to Bluetooth SIG 2025 report, Bluetooth-enabled device shipments will reach 5.3 billion units in 2025 and rise to nearly 8 billion by 2029.
So, let’s take a look at the key protocols of Bluetooth for medical devices 👇
GATT is what makes structured data exchange between your device and app possible. Using services and characteristics, GATT sends vital signs like heart rate, temperature, or glucose levels from a medical device to a mobile app.
Examples of GATT in action:
Pro tip: iOS applies stricter limits on background BLE activity compared to Android. That means you should use GATT configuration and connection interval settings to ensure uninterrupted background syncing.
L2CAP comes into play when your Bluetooth in medical devices needs to transfer more data than fits into a single BLE packet. It handles packet segmentation and reassembly, ensuring that even larger chunks of clinical data get delivered smoothly and reliably.
Think of it as your Bluetooth’s traffic control system, making sure everything streams efficiently under pressure.
SPP is a Bluetooth Classic protocol. It mimics serial cable communication but drains power quickly and isn’t well-supported by modern mobile operating systems. That’s why it’s rarely used in medical BLE setups today, unless you’re dealing with legacy hardware.
Planning to bring your Bluetooth medical monitoring devices to market? Then it’s not just about making the tech work. It’s about proving it’s safe, secure, and standards-compliant. Whether you're targeting FDA clearance or a CE mark, regulatory planning should start early in development, especially when BLE is your killer feature.

Let’s walk through what your product team should keep in mind: 👇
If your app receives health data from a medical device via Bluetooth, there’s a high chance it’s considered a medical device, under both FDA and EU MDR regulations.
That means your entire communication stack of Bluetooth in medical devices will be reviewed, including:
Even something as “technical” as how you format and transmit data can become a regulatory concern. So make sure your documentation covers it from day one.
📌 Check the FDA regulations and EU MDR regulations of Wireless Medical Devices for more details.
Absolutely, you want your BLE-enabled app to fit into clinical ecosystems. So, it needs to play well with existing systems like EHRs or cloud platforms. Hence, you need to comply with these standards:
Remember: If your app stores, transmits, or visualizes medical data over BLE, it’s not just a tech project. It’s a regulated medical product. Your compliance journey starts with smart architectural decisions.
Now, let’s explore the 4 key categories of Bluetooth medical devices with real-world examples and development tips.
While devices like Fitbit or WHOOP use Bluetooth Low Energy (BLE) to sync data like sleep and activity, they're consumer-focused. Great for wellness, but not built for clinical use.
Now compare that to a wearable Zio ECG monitor by iRhythm. It’s a FDA-cleared device designed for clinical-grade cardiac monitoring. It continuously records heart rhythms for up to 14 days, storing high-resolution ECG data. The ECG monitor transfers critical segments via BLE to a mobile app used by both patients and their doctors.

Our development tips for telehealth BLE integrations:
There are more successful real-world use cases of BLE-enabled devices in the healthcare industry. If you want to become one of them, you should think about compliance, reliability, and context-specific UX of your app. If to speak about Stormotion, it’s one of the parts of the Discovery Phase for our clients.
It’s obvious that BLE technology helps MedTech companies move faster to market, improve patient care for healthcare providers, and integrate seamlessly into digital health ecosystems. But let’s take a closer look at the other benefits of Bluetooth in medical devices for MedTech companies.
Time-to-market matters when you’re waiting for regulatory approvals or responding to investor expectations. This is where BLE gives you a head start:
Real-world example:
The iHealth Labs ecosystem scaled quickly by integrating BLE infrastructure and reusing its app backend for new devices. Its product line includes various devices, from thermometers to blood pressure monitors, and all of them are FDA-compliant.
For clinical environments, Bluetooth for wireless medical devices also removes the need for dedicated wired setups or local hubs. It leads to cutting time and cost for deployment, maintenance, and the 24/7 support department.
Device success depends not just on tech, but on how easy it is to use. It’s especially true for patients managing chronic conditions at home. BLE helps make connected care nearly invisible to the user:

Real-world example:
The Dexcom G7 uses BLE to send glucose readings to its app, which then triggers predictive alerts before levels drop or rise. This creates a continuous observation of patients’ health that improves diabetes management and reduces emergency interventions.
Bluetooth devices are now compatible with a broad digital health infrastructure.
Real-world example:
The Withings BPM Core collects blood pressure and ECG data over BLE, uploads it via Wi-Fi or cellular to the Health Mate app, and then syncs it to EHRs using FHIR. The result? Physicians get data-based clinical insights, not just raw metrics.
In other words, BLE speeds up app development, saves costs, keeps patients engaged, and integrates with digital health infrastructure.
Now, let’s take a look at challenges from the point of view of our Bluetooth medical device developer of mobile apps, Sergei Shemshur.
The main advantage of BLE is the "LE" part, low energy consumption. This is achieved by transmitting data infrequently. As a result, BLE offers limited data throughput, with a maximum speed of around 250 kbps, which makes it unsuitable for devices that need to transfer large amounts of data with low latency.
Additionally, since the maximum size of a BLE packet is 251 bytes, transmitting a large dataset requires a lot of packets. If you’re using React Native, this could negatively impact app performance, as a significant amount of time will be spent processing incoming packets.
To improve the situation, you can:
When a person constantly carries a BLE device that transmits data, intruders can track their location. Most Bluetooth medical monitoring devices still use static MAC addresses. In some cases, they could even intercept the transmitted data.
To mitigate these risks, it's important to:
The 2.4 GHz band is extremely crowded today. It’s used by Wi-Fi, other Bluetooth devices, and even microwave ovens. On top of that, the human body consists of 60% water, and water absorbs radiation in this range. As a result, the connection might break if the device and the smartphone are on opposite sides of the body.
To improve the connection reliability of Bluetooth for medical devices, you can frequently check the connection status and reconnect automatically if it's lost.
Native modules can also help with this issue, allowing you to perform checks and reconnections more efficiently without the overhead of bridging data between Native code and React Native.
Every new version of iOS and Android introduces stricter limitations on background activity. This means that when your React Native app is running in the background, some events might be missed because the JavaScript thread is suspended.

Native modules come to the help again:
These challenges can be discouraging. But you can find a Tech Partner that knows how to overcome them and can help you build the companion app for Bluetooth medical devices.

Let’s talk!
Our team has experience integrating a Bluetooth-enabled wearable device into a STEPR fitness training system. This heart rate strep is worn by the user and communicates with the trainer's terminal via the Bluetooth protocol.
The device provides real-time heart rate data, and in more advanced versions of the protocol, it also transmits information such as calories burned and RR (the RP interval represents the time between two consecutive R waves in an Electrocardiogram (ECG) waveform) intervals.
Our React Native developer, Yevhenii Burkovskyi, will share more technical details about our experience with Bluetooth for medical devices.
According to official Bluetooth SIG documentation, heart rate monitors use the Heart Rate Service (UUID: 0x180D)
and the Heart Rate Measurement Characteristic (UUID: 0x2A37)
.
The Heart Rate Measurement Characteristic
contains time-sensitive data. As such, it is classified as a time-critical characteristic.
Bit | Meaning |
---|---|
0 | Heart Rate Value Format |
1 | Sensor Contact Status present |
2 | Sensor Contact detected |
3 | Energy Expended present |
4 | RR-Interval present |
5-7 | Reserved (must be 0) |
Here is how you can integrate a BLE-enabled heart rate monitor with the fitness machine or a companion mobile app.
1. Install and link
2. Set up the BLE manager
3. Scan, Connect, and Set Notification
