The Power of Bluetooth Low Energy (BLE) in Mobile App Development
As digital transformation is reshaping every sector, the need for low-cost, energy efficient, and secure connectivity has never been more important. In the realm of mobile app development in Switzerland and beyond, Bluetooth Low Energy (BLE) is modernising how we establish these connections. As an app development company in Switzerland, we’ve witnessed first-hand how BLE fosters a seamless user experience by enabling devices to communicate without the need for an internet connection, facilitating real-time data sharing.
Bluetooth Low Energy vs Traditional Bluetooth: What’s the difference?
Bluetooth has for long been the name associated with wirelessly connecting devices over short distances. However, its high power consumption limited its applicability in scenarios where devices run on small batteries or need to operate continuously over long periods.
This is where BLE technology comes in, a power optimised variant of the traditional Bluetooth technology, paving the way for advancements in mobile application development in Switzerland and across the globe. Introduced with Bluetooth 4.0, BLE offers similar range and data transfer rates as classic Bluetooth but consumes significantly less power, allowing devices to run for months or even years on tiny coin-cell batteries. This key difference has made BLE the go to choice in mobile app development for applications that demand low power consumption and secure, robust connectivity.
BLE in Mobile App Development: Seeing it in action
There are various use cases of Bluetooth and BLE technology
1.Consumer focused IoT (Internet of things) / Connected Devices
- devices like the Fitbit or Apple Watch use Bluetooth to sync data such as step counts, heart rate, and sleep patterns to a user’s smartphone or computer.
Smart Consumer products:
- A great example is the REBO smart bottle, for which Swiss Tomato developed their mobile app. It is a revolutionary smart bottle that measures your water intake and provides personal hydration plans, where the smart bottle is connected to the app via BLE. You can read about the REBO mobile app case study here.
Smart Kitchen Appliances:
- Appliances like iKettle, smart coffee makers, and connected refrigerators use Bluetooth for control via a smartphone app and data sharing.
Smart Pet Accessories:
- There are many pet-related products that use Bluetooth, such as GPS trackers, activity monitors, and even smart toys that can be controlled via a smartphone app.
Connected Car Accessories:
- Devices such as Bluetooth-enabled dash cams, car diagnostic devices, or smartphone-controlled car starters use Bluetooth to connect with users’ smartphones for operation and data exchange.
Portable Bluetooth Speakers:
- Many portable speakers use Bluetooth connectivity to stream audio from a smartphone, tablet, or computer.
2. Medtech Wearable Health Devices
These can include various devices that are medical grade and are regulated by the FDA and have to compliant with the IEC 62304 regulations
- Glucose Monitor
- Insulin pump
- Blood pressure monitor
- ECG (electrocardiogram) monitor
- Dental treatment devices
These devices are paired with a mobile app, where the data connection can be either one-way (like recording blood pressure data) or two-way, where you can adjust settings for a device (like setting insulin dosage).
3. Smart Homes and Buildings: In smart homes and offices, BLE facilitates seamless automation and control of lighting, temperature, and security systems. It also plays a crucial role in indoor positioning systems and guiding individuals within large buildings such as shopping malls, airports, and museums.

4. Industrial IoT: BLE is indispensable in predictive maintenance and asset tracking. By installing BLE sensors on machinery, companies can monitor equipment health in real time, predict failures and schedule preventative maintenance, reducing costs and extending equipment lifespan.
5. Retail: BLE beacons have been used by retailers, who strategically place these tiny devices in stores to send targeted promotions and product information to customers’ smartphones, improving customer experience and boosting sales.
However, BLE is not without its drawbacks, despite its low power consumption, the range of BLE can be a limiting factor. While it’s enough for most consumer applications, the maximum range is typically less than that of traditional Bluetooth. Moreover, while BLE provides sufficient data transfer rates for many applications, it’s not designed for scenarios that require the streaming of large amounts of data like audio or video. This can cause challenges to be resolved within the app development team in Geneva.
In conclusion, the power efficiency of BLE, coupled with robust security and wide applicability makes it a key enabler of IoT solutions across various sectors. As industries continue to unlock its potential, BLE is set to drive unprecedented levels of efficiency and innovation in our increasingly connected world.
