Shiver: What Happens When You Network 16 BLEShark Nanos Together
Table of Contents
You bought a BLEShark Nano. You scanned some networks. You messed around with BLE, ran a captive portal, blasted some IR codes. You probably thought: "This is a lot of power for something this small."
You were right. But you were also holding one device. Standing in one spot. Seeing one slice of the wireless world around you.
Now picture this: you drop a Nano in the lobby. Another one in the server room. One more in the break room. Two on different floors. They all wake up, find each other, and start working together - scanning, relaying, sharing data across the entire space. No cables. No router. No setup headaches.
That is Shiver. And once you see what it can do, you will not want to go back to a single device.
The Problem With One Device
Every wireless tool has the same limitation: it can only see what is within range of its radio. Walk into a building with a single scanner and you get a snapshot of one area. Move to another room and you lose sight of the first one. You are always trading coverage for position.
If you have ever done a site survey, a wireless audit, or even just tried to figure out why your IoT devices keep dropping, you know the pain. You walk around, take readings, move again, take more readings. By the time you have mapped the whole space, the first readings are stale. Devices have moved. Networks have shifted. You are working with incomplete data and you know it.
Enterprise solutions exist for this problem. They cost thousands of dollars, require permanent installation, and come with licensing fees. They are built for IT departments with budgets, not pentesters, researchers, or enthusiasts who need something portable, fast, and affordable.
Shiver solves this from a completely different angle.
What Is Shiver?
Shiver is a mesh network made entirely of BLEShark Nanos. You pair two or more Nanos together and they form a self-organizing wireless network using ESP-NOW. Each node talks directly to its neighbors, relaying data across the mesh so every device sees what every other device sees.
No central hub. No access point. No internet connection required. Just Nanos, talking to each other over long-range radio, building a distributed sensor grid that covers as much ground as you need.
The name comes from what a group of sharks is called: a shiver. One shark is impressive. A shiver is something else entirely.
How Big Can It Get?
Up to 16 nodes in a single Shiver mesh.
Each node can reach the next at 70 to 200 meters depending on the environment - walls, floors, obstacles. In open space, you can push that further. Chain multiple nodes together and you are covering entire buildings, outdoor venues, warehouses, campuses.
The mesh is self-healing. If a node goes out of range or loses power, the rest of the network re-routes around it. If a new node powers on nearby, the mesh finds it and pulls it in. You do not have to babysit it.
Where Shiver Changes Everything
Full-Building Wireless Audits
This is the obvious one, and it is the one that will save you the most time.
Instead of walking floor to floor with a single device, taking notes, and trying to stitch together a complete picture later, you deploy Shiver nodes across the building. Lobby, hallways, server closet, conference rooms, parking garage. Each node scans independently and feeds its findings back through the mesh.
You get a simultaneous, multi-point view of every Wi-Fi network, every BLE device, every signal in the building. Not a snapshot from one position - a full-spectrum map from 16 positions at the same time. Networks that are invisible from the lobby might be screaming from the third floor. A rogue access point hidden behind a printer on the other side of the building shows up immediately because you have a node 10 meters away from it.
This used to require a team. Now it requires a backpack full of Nanos.
Red Team Engagements
Red teams work under time pressure. You do not have all day to walk a facility and map every wireless asset. With Shiver, you distribute nodes during the initial walkthrough - each one small enough to sit on a shelf, behind a monitor, under a desk. Within minutes, you have persistent wireless visibility across the target environment.
Run distributed deauth checks to find which networks are vulnerable. Deploy captive portals on multiple nodes with different SSIDs and different landing pages - an A/B test across physical space. Monitor which portal gets more submissions and from where. Capture handshakes from multiple vantage points simultaneously.
Every node is a set of eyes and ears that stays behind when you move to the next room.
Event and Venue Security
Conferences, trade shows, concerts, corporate events - anywhere large numbers of people and devices converge. The wireless environment at a 500-person conference is chaotic. Hundreds of phones, dozens of hotspots, rogue networks popping up, Bluetooth spam, Evil Twin attacks.
Drop Shiver nodes across the venue and you have real-time visibility into everything wireless. Spot rogue access points the moment they appear. Detect deauth attacks across every channel simultaneously - Shiver nodes can partition channels between them so the mesh collectively monitors the entire 2.4GHz band. Track signal density and see exactly where congestion is worst.
Event security teams have been asking for something like this for years. It has always been too expensive or too complicated. Shiver is neither.
IoT and Smart Building Mapping
Modern buildings are full of wireless devices that nobody tracks. BLE sensors, smart locks, thermostats, occupancy detectors, asset trackers, wireless printers, building management systems. Most organizations have no idea how many wireless devices are actually operating in their space.
Shiver gives you a complete BLE and Wi-Fi device inventory across an entire facility. Every node scans for BLE advertisements and Wi-Fi probes, aggregates by MAC address, and shows you where each device was detected and at what signal strength. Because you have multiple nodes, you can even triangulate device positions based on RSSI from different vantage points.
Found 47 BLE devices on the third floor that nobody knows about? Now you have something to investigate.
Warehouse and Industrial Environments
Warehouses are wireless nightmares. Metal shelving, concrete walls, heavy machinery - all creating dead zones and signal reflections that make single-point scanning almost useless. You can stand at one end of a warehouse with a scanner and completely miss a rogue network operating 150 meters away behind a wall of inventory.
Shiver nodes deployed at intervals throughout the space give you line-of-sight coverage everywhere. Each node sees through its local obstacles, and the mesh aggregates everything. Wi-Fi dead zones, unauthorized access points, BLE beacons on asset trackers - nothing hides when you have eyes everywhere.
Campus and Multi-Building Coverage
University campuses, corporate parks, hospital complexes - any environment where you need wireless awareness across multiple buildings. Place Shiver nodes in each building and let the mesh connect them across outdoor spaces where the long-range radio shines (50+ meters in open air, easily).
Run a security assessment across an entire campus in a single afternoon. See how wireless activity in Building A compares to Building C. Find the access point that is bridging two networks that should be isolated. A full campus sweep used to be a multi-day engagement. With Shiver, it is an afternoon.
Capture the Flag and Training Labs
Running a CTF event with wireless challenges? Shiver lets you create a distributed attack/defense environment across an entire facility. Set up portal challenges on different nodes with different difficulty levels. Run simultaneous deauth detection exercises. Create a mesh-wide BLE scavenger hunt.
For training environments and cybersecurity education, Shiver turns a classroom exercise into a building-wide operation. Students deploy nodes, run distributed scans, and learn how real-world wireless assessments actually work - not from a textbook, but from doing it across actual physical space.
Home Lab and Research
Not every use case is enterprise. If you are a researcher studying wireless protocols, BLE behavior, or RF propagation, Shiver gives you a distributed sensor network for a fraction of what academic-grade equipment costs. Set up nodes across your home, your lab, or your neighborhood (with permission) and collect data from multiple positions simultaneously.
Track how BLE advertisements propagate through different building materials. Map Wi-Fi signal degradation across distance and obstacles. Run long-duration monitoring experiments that would be impossible with a single handheld device.
Every Node Is a Full BLEShark Nano
This is the part that makes Shiver different from every other mesh or distributed sensing product out there.
Shiver nodes are not dumb repeaters. They are not single-purpose sensors. Every single node in your mesh is a fully-functional BLEShark Nano with all apps, all the pentesting features, all the IR tools - everything.
When a node is not part of a mesh, it is a standalone BLEShark Nano. When you need a mesh, pair them together and they become Shiver. When the job is done, unpair them and you have individual Nanos again. Your investment is never locked into mesh-only mode.
Buy 5 Nanos for your team. Use them individually for day-to-day work. Deploy them as Shiver when you need distributed coverage. Pull them apart when you are done. Every device works everywhere, always.
Shiver Packs
You can build a Shiver mesh with any combination of BLEShark Nanos, but we also sell them in packs specifically designed for mesh deployments:
- 3-Pack - Perfect for apartments, small offices, homes, and getting started with mesh
- 6-Pack - The sweet spot. Covers a small building. Best value for most users.
- 12-Pack - Large facilities, warehouses, campus buildings
Every pack is a collection of individual BLEShark Nanos. Nothing special, nothing locked down. They are the same Nanos you can buy individually - just bundled for mesh use.
Who Is This Actually For?
If you have ever thought "I wish I could be in two places at once" during a wireless assessment - Shiver is for you.
If you have ever lost hours walking a building with a single scanner, knowing you were getting incomplete data - Shiver is for you.
If you teach cybersecurity and want your students to experience real distributed operations instead of simulations - Shiver is for you.
If you manage a facility and genuinely have no idea how many wireless devices are operating inside it right now - Shiver is for you.
If you are a researcher who needs multi-point wireless data and your budget is not "university grant" - Shiver is for you.
Or if you just think the idea of a self-organizing mesh network made of pocket-sized hacking tools sounds incredibly cool - yeah. Shiver is for you too.
A group of sharks is called a shiver. Now you know why we picked the name.
