Drop-in firmware for Nordic SoCs that transforms standard Bluetooth into a predictable, real-time communication layer.
Works with existing Nordic nRF devices
No redesign, no recertification
Below 10 ms, even under interference
With LinkBlu RT, you choose wireless – but without the compromises.
Bluetooth Low Energy was designed for consumer devices — wearables, smart home products, and accessories.
In interference-heavy industrial environments, “best effort” connectivity leads to unpredictable latency, random disconnects, packet loss under load, and failures that only appear in production.
When wireless fails, teams often blame the hardware or even abandon wireless entirely. In most cases, the real problem is the firmware.
Long story short: You keep your device. You improve how it communicates.
LinkBlu RT is an industrial-grade, real-time Bluetooth Low Energy (BLE) firmware. It replaces standard, consumer-oriented BLE stacks with a deterministic implementation that delivers predictable latency and cable-like communication on your existing Nordic Semiconductor hardware.
Not just another BLE stack.

The problem isn’t Bluetooth. It’s how it’s implemented.
Standard Bluetooth Low Energy (LE) was designed for consumer wearables and smart home devices. It relies on non-deterministic scheduling, meaning transmission timing is not predictable.
In industrial environments, this leads to:
Control loops become unstable and systems require over-engineering to compensate.
Production timing becomes inconsistent.
Downtime and field failures increase.
Issues appear only in production, not in the lab.
Root causes remain invisible, increasing debugging time.
Wireless doesn’t have to be a gamble.
LinkBlu RT wasn’t developed in isolation: it’s the result of years of hands-on work with embedded systems, industrial wireless, and real-world RF challenges.
Our team has spent over a decade building and debugging wireless systems where reliability isn’t optional: from factory environments to high-interference production setups.
Instead of accepting “best effort” behavior, we built a deterministic approach to Bluetooth Low Energy. One that performs predictably, even under real industrial conditions.
We’ve seen where wireless breaks — and why.

DEWINE Labs’ patented software continuously monitors the Bluetooth Low Energy chips and their radio environments. Using advanced algorithms, it detects interference, heavy data loads, or other challenging conditions early on, and adapts communication parameters in real time.
Instead of accepting “best effort” behavior, we built a deterministic approach to Bluetooth LE – one that performs predictably, even under real industrial conditions.
The difference is measurable.
| Feature | Standard BLE | LinkBlu RT |
|---|---|---|
| Latency | Unpredictable (spikes >200ms) | Deterministic (<10 ms) |
| Throughput Stability | Variable under interference | Stable >700 kbit/s under real conditions |
| Traffic Handling | Single queue | Dual-channel isolation |
| Industrial RF Resilience | Low (“best effort”) | Adaptive mitigation |
| Hardware | Varies | Existing Nordic SoCs |
When reliability matters, “good enough” isn’t enough.
LinkBlu RT is ideal where:
→ Cables limit mechanical design or mobility
→ Wireless instability delays product launch
→ Hardware redesign would increase cost and timeline risk
→ Reliability is critical for automation or safety systems
Instead of redesigning your hardware to fix wireless problems, you replace the firmware layer.
No redesign, no guesswork – just predictable performance.

Still have questions? We have answers!
Yes. LinkBlu RT uses Bluetooth Low Energy (BLE) at the physical and radio level, maintaining full compatibility with BLE hardware such as Nordic Semiconductor SoCs. What changes is the firmware layer: LinkBlu RT replaces the standard, consumer-oriented BLE stack with a deterministic, real-time implementation. This allows BLE to behave predictably in industrial environments while preserving its underlying radio technology and interoperability.
No. LinkBlu RT runs on existing Nordic Semiconductor Bluetooth SoCs and typically does not require PCB changes, antenna modifications, or additional RF certifications. Because the radio hardware and frequency behavior remain unchanged, existing certification frameworks can typically remain intact. This makes LinkBlu RT suitable for both new designs and retrofitting existing products without triggering costly hardware redesign cycles.
Standard BLE firmware is optimized for flexibility, low power consumption, and consumer use cases such as wearables and smart home devices. It relies on non-deterministic scheduling and “best effort” behavior, which can result in latency spikes and unpredictable performance under interference. LinkBlu RT replaces this model with deterministic timing, explicit prioritization of real-time traffic, and improved behavior under industrial RF conditions. The result is predictable, bounded latency suitable for control and automation systems.
Yes. LinkBlu RT uses a dual-channel architecture that separates time-critical control signals from non-critical data such as logs, diagnostics, and configuration updates. This prevents background traffic from interfering with real-time communication.
Using both channels simultaneously requires two independent serial interfaces (e.g., UART, SPI, or USB) between the BLE SoC and the host. If the existing hardware design provides only one serial interface, LinkBlu RT can still operate reliably.
In single-interface configurations, the system can be configured to prioritize either deterministic real-time communication (with predictable latencies below 10ms) or higher-throughput data transfer. Full physical separation of both traffic types requires two serial interfaces.
Yes. LinkBlu RT is designed for deployment in real industrial and medical systems, not experimental or consumer environments. It addresses the failure modes commonly encountered in interference-heavy production settings and supports integration into existing hardware platforms. Its architecture is built around predictable timing and controlled behavior rather than probabilistic performance.
LinkBlu RT uses Bluetooth Low Energy (BLE) at the radio level and supports secure communication mechanisms consistent with modern industrial security requirements. Because it replaces the standard BLE firmware stack, it allows tighter control over communication behavior, traffic separation, and firmware validation. The architecture is designed to support encrypted data exchange and secure firmware operation on supported Nordic Semiconductor SoCs. Security implementation at the product level remains the responsibility of the device manufacturer.
Deterministic wireless communication means that timing behavior is predictable and bounded, rather than probabilistic. In practical terms, this means latency remains within defined limits and does not exhibit random spikes under normal operating conditions. Determinism allows engineers to design control loops and coordination mechanisms with confidence, similar to how they would design around a wired connection. LinkBlu RT achieves this by replacing non-deterministic BLE scheduling with a real-time communication model.
Standard Bluetooth Low Energy is not designed for strict real-time industrial control due to its non-deterministic scheduling model. However, when combined with a deterministic firmware layer such as LinkBlu RT, BLE hardware can support predictable, real-time communication behavior. By controlling timing, prioritization, and traffic separation, LinkBlu RT enables Bluetooth to be used in industrial environments where reliability and bounded latency are required.
In most cases, no. LinkBlu RT is a drop-in firmware replacement that runs on supported Nordic Semiconductor Bluetooth SoCs and typically does not require changes to the PCB, antenna design, or RF layout.
However, if you want to use both channels of the dual-channel architecture simultaneously, a second serial interface (UART, SPI, USB) between the BLE SoC and the host is required. If the existing hardware design only provides a single serial interface, adding a second interface may require a minor PCB modification.
Many existing designs already expose multiple serial interfaces. The exact integration impact depends on your current hardware architecture.
Yes. Under the EU Cyber Resilience Act (CRA), manufacturers are responsible for ensuring that all digital components — including wireless communication interfaces such as Bluetooth — meet defined cybersecurity requirements. While LinkBlu RT itself is firmware and not a finished product subject to certification, it is designed to support CRA-aligned system design. Its deterministic architecture, firmware control, and diagnostics help reduce risk in the wireless communication layer. Final compliance and certification remain the responsibility of the product manufacturer.
