Building Smarter Workspaces with Secure Bluetooth Connectivity
New Tech Tuesdays
Join Mouser's Technical Content team for a weekly look at all things interesting, new, and noteworthy for design engineers.
Published November 11, 2025
Take a look around and you will likely see a variety of Bluetooth®-enabled devices, from speakers and keyboards to HVAC controls and, of course, the device you’re reading this blog on. The 2025 Bluetooth Market Update predicts 5.4 billion Bluetooth devices will ship in 2025, expanding at a compound annual growth rate (CAGR) of 9 percent.[1] Commercial and consumer preferences for wireless connectivity have brought Bluetooth to nearly every vertical of electrical engineering. This week’s New Tech Tuesdays covers some interesting commercial applications that benefit from powerful, compact Bluetooth modules.
Commercial Demands for Bluetooth Connectivity
Commercial sensor and security applications increasingly rely on wireless connectivity for ease of installation and broad coverage. Bluetooth Low Energy mesh networks enable connectivity that extends far beyond the transmission range of a single Bluetooth hub, providing coverage across expansive worksites. Hundreds of temperature sensors, motion sensors, and light sensors throughout an entire building wirelessly provide information to intelligent building automation systems that can automatically adjust smart HVAC and lighting. Security sensors and smartphone-based building access also rely on Bluetooth for secure connections that are difficult to spoof when paired with Bluetooth’s distance measurements.
Industrial environments also benefit from large mesh networks of temperature, humidity, vibration, and air quality sensors. This multitude of connected sensor readings identifies unsafe working conditions or malfunctioning equipment by feeding the data into predictive maintenance algorithms.
Medical providers use a variety of Bluetooth-connected devices, such as infusion pumps, portable ultrasound machines, and blood oximeters, to quickly and conveniently create a holistic view of patient health. Interfacing patient monitoring with the local intranet provides instant updates to patients’ medical records.
Ensuring secure and efficient connectivity throughout these smarter workspaces introduces an essential design consideration.
System-on-Chip or Module?
Engineers can choose between a Bluetooth system-on-chip (SoC) or a module for adding Bluetooth connectivity to their designs. Bluetooth SoCs are small integrated circuits that contain an RF transceiver, processor, memory, and firmware for Bluetooth operation. SoCs have a lower upfront cost than modules but require more engineering work. Engineers using SoCs need to design and add matching circuits and antennas to SoCs, and then the design must be certified according to local regulations.
Modules built around SoCs also include matching circuits and antennas. They are pre-certified by the manufacturer, making them easier to drop into a design. Using modules to add Bluetooth connectivity is a great option for design teams that are not equipped for precision RF tuning or teams working on novel designs that want to reduce time to market.
The Newest Products for Your Newest Designs®
For designers looking to take advantage of the module approach to connectivity, Ezurio brings a comprehensive portfolio of connectivity solutions. The Ezurio BL54L Bluetooth modules (Figure 1) provide advanced connectivity for demanding applications with multi-protocol support for Bluetooth Core 6.0 and 802.15.4 (Thread/Matter). Based on Nordic Semiconductor’s nRF54L Bluetooth Low Energy SoC, the BL54L family of modules offers a convenient, pre-certified Bluetooth solution. A 128MHz Arm® Cortex®-M33 and a 128MHz RISC-V co-processor with 1.0MB (BL54L10) or 1.5MB (BL54L15/BL54L15µ) of non-volatile memory deliver efficient computing resources to demanding applications.

Choose from the BL54L10, BL54L15, and BL54L15µ series to get the right balance of performance and size for your application:
- BL54L10: Flexible choice for Bluetooth LE
- BL54L15: Higher performance
- BL54L15µ: Higher performance in an ultra-compact footprint
BL54L modules are designed to operate in secure medical and industrial environments with secure boot, secure firmware updates, secure storage, and physical tamper detection. They are hardened against cyberattacks, meeting PSA Certified Level 3 requirements. The modules enable faster implementation of the nRF54L’s new Bluetooth Core 6.0 features, such as Channel Sounding, Mesh Networking, LE Coded, LE 2M, extended advertising, and more.
Tuesday’s Takeaway
As Bluetooth technology continues to evolve, it is unlocking new opportunities across commercial and industrial applications. Low-power wireless connectivity now makes it possible to create smart, connected workspace environments where traditional cabling is impractical. Meeting this need, the Ezurio BL54L series delivers robust, secure, multimode connectivity in a range of size and performance options. With built-in support for Thread and Matter, the BL54L series accelerates next-generation Bluetooth Core 6.0-based designs for smart workspaces, turning design possibility into reality.
