Developer BLE Module Kit: 50KM Long-Range Bluetooth for Every Builder

RFOXiA Long Range Bluetooth Module

The Developer BLE Module Kit That Breaks Every Range Record

50KM long range BLE module for drones and autonomous systems

If you have spent any time searching for a serious wireless development platform, you already know the problem. Commodity Bluetooth modules top out at 80 to 100 meters. Military-grade long-range systems start at five thousand dollars and climbing. The space between those two extremes — the space where real builders, drone engineers, robotics developers, and IoT researchers actually live — has been empty for years.

That space now has a product.

The MultiNav Pro+ BLE Module from RFOXiA is the first true developer BLE module kit built for that gap. It delivers 50KM of Bluetooth range, 2Mbps data throughput, FCC certification, open-source firmware, and a complete mobile control ecosystem — all for $59 for two units. Nothing else on the market comes close.

This is not marketing language. These are measured specifications backed by real RF engineering. Let us walk through exactly what this module does, how it does it, and why it changes what is possible for hardware developers working in wireless.


Why Standard BLE Modules Fail Serious Developers

Most Bluetooth Low Energy modules available today were designed for consumer applications: fitness trackers, smart home devices, wireless headphones. The design priorities for those applications are cost reduction and power consumption, not range, not data rate, not reliability at distance.

The result is a class of modules that are perfectly adequate for a 10-meter bedroom or a 50-meter warehouse floor, and completely useless the moment your application needs to reach further. Building a drone that needs a 2km control link? A commodity BLE module cannot do it. Deploying a remote environmental sensor station 500 meters from your base? Forget it. Creating a mesh communication network across a field research site? Not a chance.

Developers working on these problems have been forced into one of two painful compromises: pay a fortune for professional RF systems, or cobble together workarounds using LoRa, custom RF designs, or proprietary radio protocols — each with their own limitations and development overhead.

The MultiNav Pro+ BLE Module was built specifically to eliminate that compromise.


Range Performance: What 50KM Actually Means

Long range BLE connectivity up to 50KM for drones and robots

The 50KM range figure deserves context, because range in wireless always depends on deployment conditions. Here is exactly what the MultiNav Pro+ BLE Module achieves across three real-world scenarios:

Ground-to-Ground: When one module is paired with your smartphone and the second module is paired with another user's smartphone, both on the ground, the system achieves over 5KM of reliable communication. That is a private, infrastructure-free link between two handheld devices stretching the length of five city kilometers.

Man-to-Drone: When one module is on your phone and the second is mounted on a drone or aerial platform, ground reflections are reduced and line-of-sight improves dramatically. Range in this configuration extends to 15 to 20KM. This makes the MultiNav Pro+ BLE Module one of the most capable drone control data links available to civilian developers at any price.

Drone-to-Drone: When both modules are airborne, ground-level multipath interference is eliminated entirely. In this configuration, range exceeds 50KM — performance that was previously achievable only with purpose-built RF systems costing orders of magnitude more.

These numbers are achieved through genuine RF engineering: an optimized RF front-end, external low-noise amplifiers, advanced receiver sensitivity design, and a high-gain chip antenna. This is not a software trick. It is the result of hardware built from the ground up for range.

For developers building any kind of long-range wireless application, this developer BLE module kit delivers a link budget that standard modules simply cannot approach.


2Mbps Data Rate: Fast Enough for Real Applications

Range without speed is only half the equation. Many long-range wireless solutions achieve their distance by severely throttling data rate — useful for simple telemetry but limiting for anything more demanding.

The MultiNav Pro+ BLE Module supports the full 2Mbps BLE data rate across its range. Whether you are streaming live sensor data from a remote deployment, transmitting GPS coordinates at high frequency, controlling a multi-axis robotic system in real time, or relaying compressed video metadata over a long link, the module handles it without sacrificing reliability.

For drone builders specifically, this matters enormously. A control link that lags or drops under load creates dangerous situations. The MultiNav Pro+ maintains minimal latency at distance, giving pilots and autonomous systems the responsive link they need to operate safely and effectively.


The Processing Core: STM32WB07CCV6

STM32WB07CCV6 processor powering MultiNav Pro+ BLE stack and applications

At the heart of the MultiNav Pro+ BLE Module is the STM32WB07CCV6 — a dual-core wireless microcontroller from STMicroelectronics that manages both the BLE stack and user applications simultaneously.

This architecture matters for developers. The BLE radio stack runs on a dedicated core, meaning your application code runs on a separate core without competing for processor time with the radio. The result is consistent radio performance regardless of how computationally intensive your application becomes.

The STM32WB07 family is a professional-grade choice used in industrial and commercial wireless products worldwide. It brings hardware-level security features, low-power modes for battery-conscious deployments, and a rich peripheral set that makes integration straightforward. When you are building a production system rather than a prototype, the quality of the silicon underneath matters — and this is the right silicon.


Seamless Ecosystem Integration

MultiNav Pro+ BLE module integrated with GNSS and sensor ecosystem

The MultiNav Pro+ BLE Module is not a standalone component. It is the wireless core of a complete hardware ecosystem designed to let you build fully integrated autonomous systems without sourcing and integrating unrelated boards from multiple vendors.

The module features four distinct interface groups:

  • GNSS Interface — connects directly to the MultiNav Pro+ GNSS Module for 1.5-meter accuracy position data at 18Hz fix rate
  • Sensors Interface — connects to the MultiNav Pro+ Sensors Module for environmental monitoring across temperature, humidity, pressure, air quality, accelerometer, gyroscope, and magnetometer
  • Motors and Battery Management Interface — enables direct motor control and battery monitoring for robotic and drone platforms
  • Programming Interface — integrated SWD programming access for firmware development and debugging

For developers building autonomous drones, ground robots, environmental monitoring stations, or any system that needs wireless communication, precise location, environmental sensing, and motion control together, this modular architecture eliminates weeks of integration work. Everything is designed to connect, and everything shares a common software framework.

If you are ready to explore the complete ecosystem, the RFOXiA Long Range Bluetooth Module is the starting point that makes the entire platform accessible.


RFOXiA Connect App: Complete Mobile Control

One of the most significant advantages of this developer BLE module kit over any competing wireless hardware is the RFOXiA Connect application. This is not an afterthought companion app. It is a purpose-built control and monitoring platform for the MultiNav Pro+ ecosystem.

The app delivers:

Live Map View — Real-time GPS tracking of your connected device on an interactive map, using position data from the GNSS module streamed over the BLE link.

Sensor Data Display — Live readouts from all connected sensor channels — temperature, humidity, pressure, air quality, IMU data — displayed in real time as your device streams telemetry.

PS5-Style Controller Interface — A familiar, intuitive gamepad layout for controlling drones and robots over the long-range BLE link. Responsive, low-latency, and easy to operate.

Automation Center — Define conditional behaviors, automated responses, and scripted sequences directly from the app without needing to rewrite firmware.

Critically, the RFOXiA Connect app operates completely without internet connectivity. Your long-range link is private. It runs on the BLE channel between your phone and the module — no server in the middle, no cloud dependency, no subscription required. The app is available for Android now, with iOS release imminent.


BLE Chat: Mesh Communication Without Infrastructure

BLE Chat feature enabling internet-free text voice and call communication

Beyond drone control and sensor telemetry, the MultiNav Pro+ BLE Module includes a capability that opens a completely different category of applications: BLE Chat.

BLE Chat enables direct, internet-independent communication between MultiNav Pro+ users. Text messages, data packets, and voice communication all travel over the BLE link — no cellular, no Wi-Fi, no infrastructure of any kind required.

The practical applications are significant:

  • Search and rescue operations where cellular infrastructure is down or unavailable
  • Remote field research teams coordinating across a site without reliable cell coverage
  • Disaster response scenarios where existing communication infrastructure has failed
  • Off-grid expeditions where team members need reliable communication over distances that walkie-talkies cannot cover
  • Industrial facilities where radio frequency interference makes conventional communication unreliable

For the developer community, BLE Chat also represents a building block for custom mesh network applications. The open-source firmware gives you full access to the communication stack — you can build custom protocols, routing logic, and data formats on top of the existing BLE Chat foundation.


Compact Form Factor Built for Real Deployments

Compact 57x47mm BLE module with integrated mounting frame and antenna

The MultiNav Pro+ BLE Module measures 57mm by 47mm, with a fixing frame size of 54mm by 34mm and corner mounting holes for secure mechanical integration. The integrated high-gain chip antenna extends 140mm, optimized for the RF performance described above without requiring an external antenna cable or connector.

This is a module sized for real applications. It fits on a 5-inch FPV drone frame. It integrates into a compact ground robot chassis. It mounts inside an environmental monitoring enclosure. The mechanical design was made with actual deployments in mind — not laboratory bench testing.

The onboard RTC crystal rounds out the hardware complement, providing precise timekeeping for applications that need to timestamp data, synchronize multi-node systems, or maintain accurate scheduling without external time references.


Open Source, Fully Programmable

Open source programmable BLE module with SWD interface for customization

Every aspect of the MultiNav Pro+ BLE Module firmware is open source and fully accessible through the SWD programming interface. The complete firmware repository is publicly available on GitHub, and the module ships ready to program via the integrated SWD header.

For developers who want to build custom applications on top of the hardware, this is the starting point. The existing firmware handles the BLE stack, the RF configuration, the app communication protocol, and the ecosystem module interfaces — freeing you to write application logic without reinventing the wireless layer.

For developers who want to go deeper, every layer is accessible. You can modify the BLE stack configuration, tune RF parameters for specific deployment conditions, implement custom communication protocols, or completely replace the firmware with your own application built directly on the STM32WB07 SDK.

RFOXiA Club also integrates an AI Firmware Builder that generates production-ready firmware from plain language descriptions of your application. Describe what you want to build, and the AI generates complete source code ready to compile and flash. For developers who want to move quickly from concept to working prototype, this tool reduces firmware development time from weeks to hours.

The RFOXiA Long Range Bluetooth Module page includes links to the GitHub repository and full documentation for getting started with custom firmware development.


Integrated RTC for Time-Critical Applications

MultiNav Pro+ BLE module with integrated RTC crystal for precise timing

Precise timing is often overlooked until it becomes the limiting factor in a system. Data logging applications need accurate timestamps to make logged data meaningful. Multi-node networks need synchronization to prevent packet collisions. Navigation applications need timing accuracy to correlate position data with sensor measurements.

The integrated RTC crystal in the MultiNav Pro+ BLE Module provides this precision without requiring an external clock source or network time synchronization. Whether your deployment is in a connected environment or completely off-grid, the module maintains accurate time reference for all time-sensitive operations.

This detail reflects the overall design philosophy of the MultiNav Pro+ platform: every capability that professional developers need is built in, because field deployments do not accommodate missing hardware.


FCC Certified and Ready to Ship

One detail separates the MultiNav Pro+ BLE Module from a large fraction of long-range wireless hardware available to developers: FCC certification.

FCC certification means this module has been tested and approved for legal operation in the United States. It means the RF emissions are within legal limits. It means distributors and retail channels will accept it. It means you can deploy it in commercial applications without regulatory risk.

For the developer community, certification also signals something about the engineering quality underneath. Getting through FCC testing requires hardware that actually performs consistently within specification. Modules that cut corners in RF design rarely survive the process.

All four modules in the MultiNav Pro+ ecosystem — BLE, GNSS, Sensors, and Power/Program Kit — carry FCC certification. The complete developer BLE module kit ecosystem is compliant and ready for deployment.
