One BLEShark Nano sees a room.
With Shiver, it sees the building.

BLEShark Nano is the handheld BLE, Wi-Fi, and IR research tool. Start with one; add more later if you want team kits or mesh coverage.

Why we made it

Built for BLE, Wi-Fi, and IR research

Why we made it.

Two shapes of wireless research tool exist. Rough development boards, where battery life is bad and the firmware is whoever maintained it last. Or expensive enterprise gear, much of which an ESP32 in your pocket can replicate. There wasn't a third option.

What it is

The BLEShark Nano is a pocket-sized wireless research tool, specialised for Bluetooth Low Energy and Wi-Fi 2.4 GHz. Plus infrared, because it would be silly not to.

ESP32-C3 backbone, 0.66" monochrome OLED, 6 to 12 hours of active use, USB-C. Thirty-plus features, every one of them aimed at the BLE and Wi-Fi attack surface. Specialised by choice.

Why we built it

We wanted the BLEShark Nano to feel polished at thirty-something dollars. Hand-tuned firmware. Automatic OTA updates over saved networks. Two clicks to anywhere in the UI. The kind of feel you usually get from devices that cost five times more.

Optional Mesh

When one Nano is not enough

Mesh is there when you need it.

Start with one Nano. Add three, six, or twelve when a team, class, lab, or building needs multiple wireless test points. Pick an environment. Drag a node. Click to take one offline. Watch.

Why Mesh

Room. Lab. Building.

Most people start with one Nano. Shiver is the optional mesh mode for teams and larger spaces.

Why we built it

A single Nano is the right entry point: pocketable, affordable, and ready for BLE, Wi-Fi, IR, captures, portals, updates, and field work.

Sometimes the job is bigger. A class needs multiple devices. A team wants parallel captures. A lab wants sensors in more than one corner. That is where multi-packs make sense.

Shiver is the expansion path, not a requirement. Pair multiple Nanos and they can coordinate over ESP-NOW for broader wireless research coverage.

What mesh adds

Multiple Nanos can share work across a private mesh: commands, settings, captures, short messages, and node-to-node routing.

Long Range mode is optional: roughly 200 m per hop in exchange for a slower link. It is built for owners through the automatic OTA system, so one Nano is still the place to start.
