what it does
High-throughput streaming without the BLE plumbing.

Nexus BLE Gateway
The Nexus BLE Gateway handles the full connected BLE acquisition layer — scanning, central-role connections, subscriptions, GATT reads and writes, notification forwarding, and per-stream diagnostics.
N3 Edge Intelligence Integration
The Nexus BLE Gateway is fully integrated into Nexus N3 Edge Intelligence, where plugins orchestrate sensors, store data online or offline, process and reduce streams, and power custom edge applications through the NEIA app framework.
rf survey
Map BLE Signal Quality
The RF Survey feature enables deployment validation and field mapping. It lets teams select one or more target sensors, collect repeated advertisements over fixed windows, and monitor live score, quality, trend, RSSI, and observation summaries as the sensor or gateway is moved through space.

One Gateway for Mixed Connected BLE Sensor Systems
BLE is not equal. Nexus is built for workflows where multiple sensor types run together — each with its own GATT profile, sampling behavior, configuration sequence, payload format, and live notification stream.

multi-link performance
Validated for up to 10 simultaneous connected BLE links at 60 Hz.
Nexus is built for high-rate BLE GATT notification streams. The multi-link foundation makes it well suited for richer sensor configurations where multiple devices are active at the same time and the host needs a consistent way to control, stream, and monitor them.

developer interface
Documented API, Python Tooling, Serious Streaming
Control commands are human-readable JSON. High-rate BLE GATT notification data can move through efficient binary frames. The same gateway interface supports scanning, connecting, subscribing, reading, writing, disconnecting, and status diagnostics, with Python SDK tooling for supported sensor workflows and custom integrations.

Know the Quality of Every Stream
When multiple connected BLE sensors are streaming at once, connection status alone is not enough. Nexus exposes diagnostics that help teams understand stream quality, host throughput, dropped or delayed packets, and gateway behavior during each run.

extensible architecture
A Shared Gateway Layer for Sensor-Specific Workflows
Nexus separates the reusable gateway layer from the sensor-specific integration layer. New sensor support can be added by implementing discovery rules, GATT UUIDs, configuration commands, payload parsing, and customer-facing workflows on top of the shared SDK.
Sensor-Specific Modules
Device-specific UUIDs, setup commands, timestamp parsing, and payload interpretation.
Future Sensor Ecosystem
A foundation for expanding mixed BLE sensor workflows beyond the first integrations.

The Gateway for Real BLE Sensor Systems
Nexus gives mixed sensor systems concurrent links, high-rate streaming, reusable host integration, and clear visibility into data quality — from motion to ECG and beyond.
