The ER0S EdgeBox unifies Bluetooth Mesh lighting, Modbus field devices and 2 km DECT NR+ sensor backhaul into a single stream to your BMS or cloud — maintenance-free, and built where connectivity cannot fail.
FLSEMI implements ETSI TS 103 636 Release 2 — MAC, DLC and CVG — on the Nordic nRF9151, clause by clause. Every unit is exercised against the test specification before anything is built on top of it, and then run into interference we generate on purpose. That stack ships as a product. The same bench is open to you as an engineering service.
One implementation, two transports — not two codebases. Pick the one that fits the product you already have.
Figures measured on somebody else's reference design do not govern your product. We put your device in the DUT position and measure what it actually does.
Figures come from our own reference build on the Nordic nRF9151 and move as the stack changes; the firmware is under continuous optimisation, so what governs a delivery is the version shipped with it. They are not protocol conformance results and carry no regulatory meaning. The stack has not been submitted for formal conformance testing.
An industrial IoT gateway that bridges field-side Bluetooth Mesh / NLC lighting, Modbus RTU devices and 0–10 V / DI-DO I/O to Modbus TCP, BMS or cloud over a single PoE cable. The ER0S variant adds an integrated 5G DECT NR+ radio for long-range sensor backhaul — no SIM, no cellular subscription.
A Modbus TCP server and RTU master with full NLC mesh model support, an EnOcean energy-harvesting proxy and remote OTA — housed in a metal heat-sink enclosure rated for −20 ~ +75 °C industrial environments.
Both share 10/100M Ethernet (PoE), RS-485, 2× 0–10 V, 2× DI / 4× DO, microSD and −20 ~ +75 °C operation. RF certification (NCC / CE / FCC / TELEC / RCM) is applied for per project, by target market and production version.
The EdgeBox is built on a wireless stack that combines short-range and long-range connectivity with energy that generates itself — so networks stay reliable without batteries, base stations or SIM cards.
Networked Lighting Control over Bluetooth Mesh — provisioning, scenes, scheduling and energy monitoring from a phone, scaling to 1,000+ nodes.
ETSI DECT-2020 NR (TS 103 636, Release 2) on licence-exempt spectrum — 915 MHz & 1.9 GHz NR+ band support from one image with the band chosen at start-up, self-healing decentralized mesh with no base station and no operator.
Battery-free switches and sensors harvest kinetic and ambient energy, proxied straight into the mesh — no wiring, no batteries, zero maintenance.
Networked Lighting Control over Bluetooth Mesh — provisioning, dimming, scenes and scheduling from a phone, driven by self-powered switches. One platform from indoor luminaires to city-wide street lighting.
License-exempt DECT NR+ backhaul into the ER0S EdgeBox for status and condition monitoring across large sites — long range, self-healing, no SIM and no base station.
Dimmers, wireless sensor nodes and uncooled thermal cores at the edge — all bridged to Modbus TCP, BMS and cloud by one ER0 / ER0S EdgeBox.
Bluetooth NLC constant-voltage and constant-current dimmers with battery-free wireless switches — the field devices the EdgeBox provisions and controls.
A DECT NR+ field sensor for condition, energy and environmental data on the Nordic nRF9151 SiP and nRF5340 SoC — backhauled to the EdgeBox with no SIM or cellular subscription.
The CT11-USB uncooled thermal camera core — 640×512 LWIR, plug-and-play over a single USB connection with UVC video and CDC control.
One gateway bridges Bluetooth Mesh lighting, Modbus RTU field devices and DECT NR+ sensors to Modbus TCP, BMS or cloud over PoE — carrying multiple radio stacks on board, including FLSEMI's US-developed DECT NR+ MAC. A Matter-over-Ethernet stack also connects Matter devices to Apple HomeKit / HomePod and other smart-home ecosystems.
Early installations across demanding real-world environments — from semiconductor fabs to campus lighting, highways and street infrastructure.
