Long Range Bluetooth Chip That Redefines What BLE Can Do

The Long Range Bluetooth Chip Engineered for 50KM — Not 50 Meters

Most engineers accept a quiet lie about Bluetooth: that it is fundamentally a short-range technology. Commodity modules top out at 80 to 100 meters under ideal conditions. Walls, interference, and real-world RF environments reduce that further. For decades, if you needed wireless communication beyond 100 meters at an accessible price, you were simply out of options.

The MultiNav Pro+ BLE Module from RFOXiA exists to destroy that assumption completely.

This is a long range bluetooth chip engineered from the ground up to reach distances that no off-the-shelf BLE module comes close to achieving — 5KM ground-to-ground when paired with a smartphone, 15 to 20KM man-to-drone, and a staggering 50KM drone-to-drone when both nodes are airborne and ground reflections are eliminated. It does this at a 2Mbps data rate, with FCC certification, and at a price point — $59 for two units — that makes it accessible to every serious builder, not just those with defense-grade budgets.

This post covers everything you need to know: the hardware architecture that makes these numbers real, the ecosystem it integrates with, the applications it unlocks, and why there is no other long range bluetooth chip on the market that competes with it at this price.

Why Commodity BLE Modules Fail at Long Range

To understand what makes the MultiNav Pro+ different, it helps to understand why standard Bluetooth chips fall short.

A typical BLE module — the kind you find on development boards and in consumer IoT devices — uses a chip-integrated antenna with minimal RF front-end amplification. The transmit power is low, the receiver sensitivity is average, and the antenna gain is modest. This is perfectly adequate for a smart home sensor sitting 10 meters from a hub. It is completely inadequate for any outdoor, industrial, or mobile application that requires real distance.

Achieving genuine long range over Bluetooth requires a fundamentally different hardware approach:

A high-gain antenna — not the tiny chip antenna on a commodity module
External RF front-end amplifiers — both transmit power amplifier and low-noise receive amplifier
Optimized receiver sensitivity — pushing the noise floor down so weak signals can be decoded
A capable processing core — one that can handle the BLE stack and user applications simultaneously without dropped packets

The MultiNav Pro+ addresses every one of these requirements. The result is a long range bluetooth chip that achieves range figures previously only seen in military and industrial systems costing thousands of dollars.

Core Specifications: What Makes This Module Different

Range Performance

The range figures for the MultiNav Pro+ are not theoretical maximums pulled from a datasheet under laboratory conditions. They reflect real-world deployment scenarios:

5KM ground-to-ground: Both BLE modules are at ground level, each paired with a smartphone. This is the most RF-hostile scenario — ground reflections, obstructions, and environmental interference all work against the signal. The module achieves 5KM under these conditions.
15–20KM man-to-drone: One module is carried by a person on the ground, the second is mounted on a drone. Elevation dramatically reduces ground-plane interference, extending the effective range to 15–20KM.
50KM drone-to-drone: Both modules are airborne. Ground reflections are eliminated entirely. The line-of-sight path between two elevated nodes allows the full RF capability of this long range bluetooth chip to be realized — 50 kilometers of reliable BLE communication.

There is no other commercially available BLE solution at any price that matches these figures. The gap between the MultiNav Pro+ and the next best option is not incremental — it is a category difference.

Data Rate

2Mbps. This is not a low-bandwidth telemetry link. The MultiNav Pro+ delivers broadband wireless performance at long range, enabling real-time sensor data streaming, live GPS tracking, video telemetry metadata, and responsive control of drones and robots — all simultaneously if required.

Processing Core

At the heart of the MultiNav Pro+ is the STM32WB07CCV6 — a dual-core wireless microcontroller from STMicroelectronics. One core handles the BLE stack, maintaining connection integrity and managing the RF protocol. The other core is entirely free for user applications: sensor fusion, flight controller logic, data logging, custom communication protocols — whatever your project demands.

This architecture ensures that running complex user code never degrades wireless performance. Your BLE link stays clean while your application does its work.

Physical Form Factor

The module measures 57mm × 47mm with a fixing frame size of 51mm × 39mm and corner mounting holes for secure mechanical integration. The integrated high-gain antenna extends to 140mm. Despite its professional-grade capability, this is a compact form factor suitable for drone frames, robotic platforms, and field devices where space is constrained.

The onboard mounting holes mean you can secure the module directly to your PCB, drone frame, or enclosure without external brackets or adapters.

High-Speed Data Transmission at Range

The combination of 50KM range and 2Mbps data rate is what separates this long range bluetooth chip from every alternative on the market. Traditional long-range wireless solutions — LoRa, for example — sacrifice data rate for distance. You get kilometers of range but only kilobits per second of throughput. That is fine for sending a temperature reading every 30 seconds. It is completely inadequate for drone telemetry, real-time control, or live sensor streaming.

The MultiNav Pro+ delivers both. At 2Mbps you can stream:

Real-time GPS coordinates at high update rates
Live environmental sensor data (temperature, pressure, air quality, humidity)
Control commands with latency low enough for responsive flight control
Bidirectional data for closed-loop autonomous systems

This is the data rate of a high-speed USB connection, delivered wirelessly at distances that make cellular networks look like they are barely trying.

Seamless Ecosystem Integration

The MultiNav Pro+ is not just a standalone long range bluetooth chip — it is the wireless backbone of a complete hardware ecosystem. The module is designed to interface directly with three companion modules:

GNSS Module: 1.5-meter accuracy at 18Hz update rate for tracking fast-moving platforms
Sensors Module: Seven environmental sensors — temperature, humidity, pressure, air quality, accelerometer, gyroscope, magnetometer — on a single board
Power/Program Kit: Supercapacitor-based power with 5-minute charge and 24-hour runtime, plus integrated STLink programmer

All four interfaces on the BLE module — GNSS, Sensors, Motors & Battery Management, and Programming — are designed for direct connection to these companion modules. The result is a unified autonomous system platform where every subsystem communicates through a single integration layer.

For drone builders, this means GPS-tracked autonomous flight with live environmental monitoring and 50KM wireless control in one compact stack. For IoT engineers, it means a complete field node with precision location, multi-sensor data acquisition, long-range data backhaul, and professional power management — without designing a single PCB from scratch.

If you want the complete stack, the RFOXiA Long Range Bluetooth Module is available as part of the Developer Bundle, which includes all four modules at a significant discount.

RFOXiA Connect App: Control Without Infrastructure

Hardware capability means nothing without usable software. The RFOXiA Connect app — available for both iOS and Android — provides a professional control and monitoring interface for the MultiNav Pro+ module.

The app delivers:

PS5-style controller interface for drone and robot control — a familiar, ergonomic layout that pilots and roboticists will recognize immediately
Live map view with real-time GPS tracking plotted directly on a map — no separate ground station software required
Live sensor data display — temperature, humidity, pressure, air quality, and inertial data visible in real time
Automation center — define behaviors, triggers, and conditional actions without writing firmware
Full offline operation — the app communicates with the BLE module via Bluetooth and works completely without internet connectivity. No cellular, no Wi-Fi, no cloud dependency.

For drone operators flying in remote locations, this matters enormously. Your control link and data stream operate independently of any infrastructure. If the tower is down, if you are in a valley with no signal, if you are flying offshore — the app and the module keep working.

The effective control range from a handheld device to a drone is 15–20KM — a distance that exceeds virtually every consumer RC system available today at any price point.

BLE Chat: Internet-Independent Communication

The MultiNav Pro+ includes a mesh communication capability that the RFOXiA team calls BLE Chat. When multiple users each have a BLE module, they can establish direct text, data, and voice communication with each other — completely without internet connectivity, cellular networks, or any fixed infrastructure.

This has immediate practical applications:

Disaster response teams operating in areas where infrastructure has been destroyed
Remote expeditions in mountains, deserts, or maritime environments far from cellular coverage
Field research teams coordinating across large geographic areas
FPV racing and drone event operations where radio congestion makes conventional comms unreliable
Off-grid communities establishing local communication networks

At 5KM ground-to-ground range between users, a mesh of several BLE module nodes can cover tens of kilometers of territory with no recurring cost, no subscriptions, and no dependency on any external system.

Open Source and Fully Programmable

RFOXiA is committed to genuine openness. The MultiNav Pro+ BLE module is fully programmable via SWD (Serial Wire Debug), and complete source code access is available through the RFOXiA Club platform.

This means:

You can read, modify, and redistribute the firmware
You can implement custom BLE profiles and services
You can integrate the module into proprietary systems with full control over the communication layer
You are not locked into RFOXiA's app or platform if your application requires custom software

For engineers who need to embed a long range bluetooth chip into a product they are building, this openness is essential. You need to own your firmware stack. The MultiNav Pro+ lets you do exactly that.

The AI Firmware Builder in RFOXiA Club accelerates this further. Describe your application in plain language — "I need the module to transmit GPS coordinates and battery voltage from a drone to a ground station every 100ms with packet loss detection" — and the AI generates production-ready firmware with full source code. What used to take weeks takes hours.

Integrated Real-Time Clock

For applications requiring synchronized data logging, time-stamped telemetry, or scheduled transmission, the MultiNav Pro+ includes an integrated RTC crystal that provides accurate real-time clock functionality without requiring an external component.

In autonomous systems, precise timing is not optional. When you are correlating GPS data with sensor readings, synchronizing multiple nodes in a mesh network, or logging events that need to be replayed in time order, an accurate onboard clock is fundamental infrastructure. The MultiNav Pro+ includes it as a standard feature.

FCC Certification: Ready for Real Deployment

One of the most important differentiators of the MultiNav Pro+ that engineers often overlook when evaluating modules is regulatory certification. The MultiNav Pro+ BLE module is FCC certified.

This matters for several reasons:

Legal deployment in the United States: Uncertified RF devices cannot legally be operated in most commercial or public contexts in the US. FCC certification means you can deploy this module without restriction.
Distribution eligibility: Major electronics distributors — DigiKey, Mouser, Element14 — require FCC certification as a baseline qualification. RFOXiA is certified and pursuing listings on these platforms.
Product integration: If you are building a product that incorporates the MultiNav Pro+ and selling it, the module's FCC certification can simplify your own product's certification path.
Trust signal: Certification requires real-world testing of RF emissions, interference, and performance. A certified module is a module that has been verified to actually work as specified.

No other long range bluetooth chip at this price point combines these range specs with FCC certification. That combination is what makes the MultiNav Pro+ a professional tool rather than an experiment.

Applications: Who Uses This Module and Why

Drone Builders and FPV Pilots

The drone community has long been constrained by the range limitations of available control links. ExpressLRS and similar systems provide good range but limited data integration. The MultiNav Pro+ gives drone builders a 20KM control link with live GPS tracking and full sensor telemetry through a single module pair — all managed through the RFOXiA Connect app on a standard smartphone, without separate ground station hardware.

Robotics Engineers

Long-range ground robots — for agriculture, inspection, search and rescue, and research — need reliable communication links that work across hundreds of meters to kilometers of varied terrain. The MultiNav Pro+ delivers this at a cost that makes it viable for research budgets and startup products alike.

IoT Developers and Field Researchers

Deploying sensor nodes in remote locations — environmental monitoring stations, agricultural sensors, industrial equipment monitoring — has always required either cellular connectivity (recurring cost, coverage-dependent) or proprietary LPWAN solutions (limited data rate, locked ecosystems). The MultiNav Pro+ offers a third path: private, high-speed, long-range wireless networking that you own completely.

Data Network Contributors

RFOXiA operates a live data monetization network. Deploying a Sensors Module with a BLE Module as a verified outdoor node generates daily rewards for contributing hyper-local environmental data. Early network participants earn the highest locked-in rates. The hardware pays for itself over time.

Pricing and Availability

The MultiNav Pro+ BLE Module is priced at $59 for two units — making it the most affordable long range bluetooth chip available with these specifications by a significant margin.

For comparison:

Commodity BLE modules: $5–15 each, 80–100m range
The next step up in long-range wireless performance: $500–5,000+, proprietary ecosystems, no app, no data network

The MultiNav Pro+ occupies a market position that previously did not exist: professional long-range wireless performance at maker-accessible prices.

Inventory is currently in stock and shipping. You can order the RFOXiA Long Range Bluetooth Module directly from the RFOXiA Club store.

For engineers who want the complete ecosystem, the Developer Bundle includes the BLE Module, GNSS Module, Sensors Module, and Power/Program Kit at a bundled price that makes the individual module cost even more compelling.
