RFOXiA BLE Module: The 50KM Long-Range Bluetooth Module Redefining Wireless Development

RFOXiA BLE Module — Professional Long-Range Connectivity at a Price Every Builder Can Access

Wireless development has always had a gap. On one side, you have commodity Bluetooth modules topping out at 80–100 meters. On the other, military-grade long-range communication systems that cost $5,000 or more. For drone builders, robotics engineers, IoT developers, and researchers, there has never been a credible middle ground — until now.

The RFOXiA BLE module, known as the MultiNav Pro+, changes everything. With verified range of up to 50KM between two modules, a 2Mbps data rate, FCC certification, and a price of just $59 for two units, this is the most capable long-range Bluetooth module ever offered at maker-accessible pricing.

This is not a hobbyist toy. This is professional-grade wireless hardware built for people who are serious about what they create.

What Makes the RFOXiA BLE Module Different?

Most Bluetooth modules on the market use standard RF front-ends with no external amplification and minimal sensitivity optimization. They are designed for consumer applications — connecting a phone to a speaker, a keyboard to a laptop. They were never intended for the field.

The MultiNav Pro+ was designed from the ground up for outdoor, field, and aerial deployment. It achieves its extraordinary range through a combination of an optimized RF front-end, external amplifiers, and advanced receiver sensitivity engineering. No other commercially available Bluetooth module reaches these distances. No military system comes close to this price point.

Here is what you get with the RFOXiA BLE module:

5KM ground-to-ground range when paired with a smartphone
15–20KM man-to-drone range for aerial applications
50KM drone-to-drone range when both modules are airborne and ground reflections are eliminated
2Mbps data rate for low-latency, high-throughput communication
FCC certified — ready for legal deployment in the United States and internationally
$59 for two units — no competing product exists at this specification and price combination

Range Explained: Why 50KM Is Real

Skepticism is reasonable. Bluetooth and 50KM do not usually appear in the same sentence. Here is the engineering explanation.

Bluetooth range in standard modules is limited by low transmit power, basic antenna designs, and no external amplification. Commodity modules operate within what the SoC reference design specifies — typically 0dBm to 4dBm transmit power and receiver sensitivity around -90dBm.

The MultiNav Pro+ uses a high-gain chip antenna combined with an RF front-end amplifier that dramatically extends both transmit power and receiver sensitivity. The result is a link budget that supports the following real-world scenarios:

Ground-to-Ground (5KM): When one module is paired with a smartphone and the second module is paired with another smartphone, the ground environment introduces multipath reflections and obstacles. The link still reaches 5KM — a figure no commodity module approaches.

Man-to-Drone (15–20KM): When the second module is elevated on a drone, ground reflections are reduced significantly. Line-of-sight improves and range extends to 15–20KM. This is the primary use case for FPV pilots and drone builders who need reliable telemetry and control beyond visual line of sight.

Drone-to-Drone (50KM): When both modules are airborne, ground multipath reflections are virtually eliminated. Pure line-of-sight propagation allows the link budget to fully express itself. 50KM is the result.

These are not theoretical maximums. These are the distances the hardware achieves.

Built on the STM32WB07: A Processing Core Worthy of the Specs

At the heart of the RFOXiA BLE module is the STM32WB07CCV6, a dual-core wireless SoC from STMicroelectronics. This processor manages the BLE radio stack independently from the application layer, which means your code runs without competing with the communication stack for processing resources.

The result is optimal performance, low latency, and the flexibility to run complex user applications alongside the BLE link without degradation. Whether you are streaming sensor telemetry, processing control commands, or running onboard logic, the STM32WB07 handles it with the headroom to spare.

For developers who want to customize firmware behavior, the module is fully open source and programmable via SWD. Full source code is available on the RFOXiA GitHub repository, and the AI Firmware Builder in RFOXiA Club can generate production-ready firmware from a plain-language description of your application.

2Mbps Data Rate: Speed That Matches the Range

Range without speed is only half the capability. The MultiNav Pro+ supports up to 2Mbps data throughput — the maximum BLE data rate available in the specification.

For drone control applications, this means control commands and telemetry data travel with minimal latency. For sensor data applications, this means you can stream continuous high-resolution data streams without bottlenecks. For robotic systems, this means real-time responsiveness even at distances that would be impossible with any other Bluetooth module.

The 2Mbps data rate combined with 50KM range positions this module in a category that previously did not exist at this price point. Long-range and high-speed. Both. Together.

Four Interfaces. One Module. Complete Integration.

The MultiNav Pro+ was designed for real applications, not just benchmarks. It features four distinct hardware interfaces:

GNSS Interface — for connection to the MultiNav Pro+ GNSS module (1.5m accuracy, 18Hz fix rate)
Sensors Interface — for connection to the MultiNav Pro+ Sensors module (7 sensors: temperature, humidity, pressure, air quality, accelerometer, gyroscope, magnetometer)
Motors and Battery Management Interface — for robotic and drone motor control and power monitoring
Programming Interface — integrated STLink programmer access for firmware development and updates

This is not a standalone module. It is the core of a complete wireless development ecosystem. When combined with the GNSS module, Sensors module, and Power/Program Kit into the Developer Bundle, you have a unified platform for autonomous systems, environmental monitoring, field research, and data collection — all in one integrated, FCC-certified stack.

If you are building something that moves, senses, communicates, or collects data, the RFOXiA MultiNav Pro+ BLE module is the foundation. Explore the full ecosystem here.

RFOXiA Connect App: Your Hardware, In Your Hand

Hardware without a control interface is just a board. The RFOXiA Connect app transforms your module into a fully operational command-and-control system accessible from any iOS or Android device.

The app features two primary screens:

Control Screen:

PS5-style controller interface for drone and robot operation
Live map with real-time GPS tracking
Live sensor data visualization
Pairs with the BLE module over Bluetooth
Functions entirely without internet connectivity — no servers, no towers, no subscriptions

Chat Screen:

Long-range mesh communication between multiple RFOXiA users
Completely internet-independent — uses BLE modules as communication nodes
Applications include disaster response, remote expedition coordination, off-grid team communication, and field research

The range of this system is determined entirely by the hardware — which means up to 20KM between a ground operator and a drone. The app is the interface. The module is the engine.

Android is live. iOS is pending App Store approval.

BLE Chat: Off-Grid Communication Without Infrastructure

BLE Chat is one of the most distinctive capabilities of the RFOXiA BLE module and one that addresses a real-world problem that grows more visible every year.

When cellular infrastructure fails — during natural disasters, in remote terrain, or in emergency situations — communication fails with it. BLE Chat creates a direct, mesh-capable communication network between MultiNav Pro+ users using only the modules themselves. No internet. No towers. No centralized servers. Just direct, encrypted, long-range communication between people who need to stay connected.

Text, data, and voice communication between BLE Chat users is possible at the full range the hardware supports — up to 5KM ground-to-ground, and further when modules are elevated. For search and rescue teams, field researchers, remote expedition members, and emergency responders, this capability is not a feature — it is a mission-critical tool.

Compact, Durable, and Designed for the Field

The MultiNav Pro+ measures 57mm x 47mm with a fixing frame of 54mm x 34mm featuring corner mounting holes. The antenna is 140mm, integrated as a high-gain chip antenna that delivers strong signal performance without the need for external antenna add-ons.

The form factor was designed for integration. Whether you are mounting this module inside a drone frame, a weatherproof enclosure, a ground vehicle, or a custom PCB stack, the dimensions and mounting holes accommodate standard hardware configurations.

The onboard RTC crystal provides precise timing for synchronization-sensitive applications — critical for navigation systems, time-stamped data logging, and coordinated multi-node deployments.

At 57mm x 47mm, you are integrating one of the most capable long-range wireless modules ever produced. That the size fits in your palm is a feature, not a compromise.

Open Source and Programmable: Your Hardware, Your Rules

RFOXiA does not lock you into proprietary ecosystems. The MultiNav Pro+ firmware is fully open source, and the module is programmable via SWD using the integrated STLink interface included in the Power/Program Kit.

This means:

Full source code access — read it, modify it, learn from it
Custom firmware development for any application
SDK access for developers building on top of the platform
AI Firmware Builder in RFOXiA Club for generating production-ready firmware from plain-language descriptions

For developers who want to ship products built on this module, the open-source approach means you are never dependent on RFOXiA providing firmware updates to support your application. You own the code. You own the capability.

For researchers who need to understand exactly what their hardware is doing, full source code transparency means no black boxes.

Precise Timing with Integrated RTC

Time synchronization is one of the most overlooked requirements in wireless system design — until it fails. The MultiNav Pro+ includes an integrated RTC crystal that provides precise, reliable timing for applications where synchronization matters.

For navigation applications, time accuracy ensures that GNSS data and BLE telemetry are correctly correlated. For multi-node deployments, the RTC enables synchronized data collection across distributed sensors. For time-stamped logging in field research, it ensures data integrity without relying on external time references.

The RTC is not an afterthought. It is a signal that this module was designed by someone who has built real systems and knows what those systems need to function correctly in the field.

Who Is This Module For?

The RFOXiA BLE module was built for a specific kind of person. Not the casual hobbyist. Not the enterprise buyer with a military budget. The builder who is serious about what they create and needs hardware that is equally serious.

Drone builders and FPV pilots who need reliable long-range telemetry and control beyond the limits of any commodity radio system.

Robotics engineers who need low-latency, high-throughput communication between ground control and autonomous systems at distances commodity modules cannot approach.

IoT developers building field-deployed sensor networks where cellular infrastructure is unavailable or cost-prohibitive.

Researchers who need GPS-verified environmental data from distributed sensor nodes with real-time streaming capability.

Emergency response and expedition teams who need communication infrastructure that works without any existing infrastructure.

If you belong to any of these groups, the commodity BLE module market has not served you. It has asked you to compromise on range, on capability, on reliability. The RFOXiA Long Range Bluetooth Module does not ask you to compromise.

The RFOXiA Ecosystem: More Than a Module

FCC Certified. Ready to Ship. No Waiting.

One of the most important facts about the RFOXiA BLE module is what it already is: FCC certified, in stock, and shipping.

This is not a crowdfunding concept. This is not a prototype. RFOXiA has completed four Kickstarter campaigns, established manufacturing infrastructure in China, and has 680 units of the MultiNav Pro+ BLE module in inventory right now.

FCC certification means this module is legally deployable in the United States without additional regulatory work on your part. It means distributors can carry it. It means you can integrate it into your product without certification liability. For professional developers and companies building products, FCC certification is not optional — and it is already done.

Why Now?

The long-range wireless hardware market is at an inflection point. Drone applications are expanding rapidly. IoT deployments in agriculture, infrastructure, and environmental monitoring are growing.
