FCC Approved Long Range Module That Redefines What Bluetooth Can Do

The FCC Approved Long Range Module Built for Builders, Pilots, and Engineers

If you have spent any time in the wireless development space, you already know the frustration. Commodity Bluetooth modules top out at 80 to 100 meters in ideal conditions. Industrial long-range solutions cost thousands of dollars and are wrapped in military procurement paperwork. The gap between what makers can afford and what professional applications demand has always felt impossible to close — until now.

The MultiNav Pro+ BLE from RFOXiA is an FCC approved long range module that shatters the range ceiling for Bluetooth development hardware. We are not talking about a modest improvement. We are talking about a 50KM module that ships for $59, carries full FCC certification, and integrates into a complete development ecosystem that most commercial IoT platforms cannot match.

This post breaks down everything you need to know — the specs, the architecture, the ecosystem, and why this module occupies a category that simply did not exist before.

Why FCC Certification Changes Everything for Long-Range Bluetooth

FCC certification is not a marketing checkbox. It is the technical and legal foundation that separates a module you can actually deploy from one that creates legal and interference liability the moment it leaves your bench.

For a long-range wireless module operating at the power levels required to reach 5KM ground-to-ground or 50KM drone-to-drone, FCC certification confirms that the RF front-end, power output, frequency behavior, and spurious emissions all meet federal standards. That means you can deploy the MultiNav Pro+ in commercial applications, ship it in products, integrate it into customer-facing systems, and cross into distribution channels that require regulatory compliance — all without going back to the drawing board.

Every module in the RFOXiA product line carries FCC certification. That is not accidental. It reflects a product philosophy built around professional-grade hardware accessible to independent developers and small teams, not just enterprise procurement teams with dedicated compliance departments.

50KM Range: What the Numbers Actually Mean

The headline number is 50KM. That is the drone-to-drone range when two MultiNav Pro+ BLE modules are paired together and both are airborne, eliminating ground reflections and multipath interference. But range performance across deployment scenarios breaks down as follows:

Ground-to-ground: Over 5KM when each module is paired with a smartphone on the ground
Man-to-drone: 15 to 20KM when one module is on the ground paired to a phone and the second is mounted on a drone
Drone-to-drone: Beyond 50KM when both modules are airborne

These numbers are achieved through optimized RF front-end design, external amplifiers, and advanced receiver sensitivity engineering — not by bending wireless physics. The result is a performance envelope that commodity BLE modules cannot approach under any conditions.

For FPV pilots, drone builders, and field researchers, the practical implication is significant. You are no longer limited to line-of-sight distances measured in hundreds of meters. You are operating with a communication link that extends well beyond visual range, completely independent of cellular infrastructure, WiFi networks, or proprietary radio systems.

Technical Specifications Deep Dive

Processing Core: STM32WB07CCV6

At the heart of the MultiNav Pro+ BLE is the STM32WB07CCV6 microcontroller, which handles both the BLE stack and user application logic simultaneously. This dual-function architecture means the module is not just a radio — it is a programmable embedded system with significant compute available for real applications.

The STM32WB series is a well-documented, widely supported platform with strong toolchain support, extensive community resources, and long-term supply availability. That matters for anyone building a product around this module — you are not locked into a proprietary silicon ecosystem with uncertain future availability.

2Mbps Data Rate

Long range without throughput is only half useful. The MultiNav Pro+ BLE supports up to 2Mbps data transmission, enabling real-time sensor streaming, live GPS telemetry, control signal transmission, and bidirectional data exchange without the latency penalty that typically comes with extended range radio systems.

For drone control applications where latency directly affects flight stability, or for IoT deployments where data density determines the value of the sensor network, 2Mbps at long range is a combination that defines a new performance category.

Compact and Mountable Form Factor

The module measures 57mm x 47mm with a fixing frame size of 54mm x 34mm and corner mounting holes. The integrated high-gain chip antenna eliminates the need for external antenna routing in most deployment scenarios. Antenna length is 140mm, and onboard fixing frame holes are positioned at 51mm x 39mm for secure mounting in drone frames, enclosures, and custom PCB integrations.

For a module delivering 50KM range capability, this form factor is genuinely compact. Drone builders and robotics engineers working in space-constrained designs can integrate this without the mechanical penalty that traditional long-range radio systems impose.

Integrated RTC Crystal

An onboard RTC crystal provides accurate timing for synchronization-dependent applications. Navigation systems, data logging deployments, and multi-node sensor networks all benefit from precise time references at the hardware level rather than relying on software-layer time management.

Four Interface Architecture: GNSS, Sensors, Motors, Programming

The MultiNav Pro+ BLE is not designed to operate in isolation. It exposes four distinct interface types — GNSS, Sensors, Motors and Battery Management, and Programming — making it the hub of a larger system rather than a standalone radio.

This architecture is what separates the MultiNav Pro+ from any generic BLE module available today. The interfaces are designed specifically to mate with the rest of the MultiNav Pro+ ecosystem, enabling plug-and-play integration of precision location, environmental sensing, motor control, and firmware development into a unified platform.

For developers building autonomous systems — whether ground robots, aerial platforms, or fixed IoT installations — the ability to stack GNSS precision location, multi-sensor environmental data, and long-range wireless communication on a single integrated platform dramatically reduces system complexity and development time.

RFOXiA Connect App: Control at Range

The MultiNav Pro+ BLE pairs with the RFOXiA Connect mobile app on both iOS and Android. The app provides two primary operational modes that cover the two most common deployment scenarios.

Control Mode delivers a PS5-style controller interface with live map GPS tracking, real-time sensor data display, and configurable control outputs. The entire control session runs without internet connectivity — the BLE module handles the link directly between the app and the target system at whatever range the hardware supports.

BLE Chat Mode establishes internet-independent mesh communication between multiple RFOXiA users. Text, data, and voice communication routes through the BLE network with no cellular or WiFi dependency. For field teams, disaster response operations, remote research deployments, and off-grid expeditions, this creates a private communication network with range measured in kilometers.

The combination of hardware-level range and a polished mobile interface is one of the clearest differentiators in the MultiNav Pro+ package. You are not writing serial commands to a terminal — you are operating a professional control system from your phone.

BLE Chat: Communication Without Infrastructure

The BLE Chat feature deserves its own discussion because it addresses a problem that most wireless developers have encountered but few products have solved at this price point.

When you need to communicate across kilometers without internet access — whether you are coordinating a drone inspection team in a remote facility, supporting search and rescue operations, or running a research expedition far from cellular coverage — you need a communication link that does not depend on infrastructure that may not exist where you are operating.

The BLE Chat functionality on the MultiNav Pro+ creates exactly that. Direct, internet-independent communication between users, at ranges that commodity Bluetooth devices cannot touch, through a clean mobile interface that does not require technical configuration.

For professional applications in infrastructure-sparse environments, this is not a nice-to-have feature. It is operational infrastructure that the MultiNav Pro+ BLE delivers at a price that makes it accessible for field deployment without enterprise procurement.

Open Source and Fully Programmable

The MultiNav Pro+ BLE ships with full open-source firmware access and SWD programmability. The complete firmware repository is available on GitHub at github.com/RFOXiA/MultiNav-Pro-Long-Range-BLE-Module-Firmware-STM32WB07, and the module is designed to be customized at every level of the stack.

For developers who need to implement proprietary protocols, custom data structures, application-specific power management, or specialized control loops, full source access means you are not constrained by the default firmware behavior. The module becomes whatever your application requires it to be.

RFOXiA Club also includes an AI Firmware Builder that generates production-ready firmware from plain-language application descriptions. For teams without dedicated embedded firmware engineers, this dramatically compresses the development timeline from months to hours.

Who Is the MultiNav Pro+ BLE Built For?

FPV Pilots and Drone Builders

The man-to-drone range of 15 to 20KM with a $59 two-unit kit represents a fundamental shift in what independent drone builders can deploy without commercial licensing. Beyond visual line of sight operations, long-range inspection, and telemetry-heavy autonomous missions all become accessible with the MultiNav Pro+ as the communication backbone.

Robotics Engineers

Ground robots operating across large facility footprints, agricultural automation systems, and field robotics research all benefit from reliable long-range bidirectional communication. The motor and battery management interface makes the MultiNav Pro+ a natural control hub for mobile robotic platforms.

IoT Developers

Dense sensor networks across large geographic areas — agricultural monitoring, smart city deployments, industrial site monitoring — require wireless links that commodity BLE cannot provide. The MultiNav Pro+ BLE, combined with the Sensors Module and data network contribution program, creates a hardware foundation for large-scale IoT deployments with a direct monetization path.

Field Researchers and Expedition Teams

Scientific field work in remote environments demands hardware that functions without infrastructure. The BLE Chat capability, combined with GPS tracking and environmental sensing through the ecosystem modules, makes the MultiNav Pro+ a complete field communication and data collection platform.

Competitive Position: What You Are Not Finding Elsewhere

The market reality for this specification profile is straightforward. Commodity BLE modules — from Silicon Labs, Nordic, or generic Chinese manufacturers — reach 80 to 100 meters under ideal conditions. They cost $5 to $15 per unit. They have no ecosystem, no app integration, no data network, and no path to 50KM range regardless of RF optimization.

Military and industrial long-range wireless systems reach 150KM and beyond. They cost $5,000 to $50,000+. They are not accessible through normal distribution channels, do not integrate with maker-compatible development tools, and do not come with AI firmware generation or a mobile control app.

The MultiNav Pro+ BLE is a genuine FCC approved long range module occupying the space between these two poles — a space that has been functionally empty until now. For developers who need professional-grade long-range wireless performance and cannot justify enterprise procurement costs, this module exists specifically to fill that gap.

If you are ready to work with an RFOXiA Long Range Bluetooth Module that delivers professional range at maker-accessible pricing, the MultiNav Pro+ BLE ships today.
