BLED112-V1 Descripción general
A BLE USB dongle is a complete wireless connectivity module that integrates the Bluetooth radio, a microcontroller running the BLE protocol stack, and an antenna into a USB stick. In the connectivity hierarchy it sits at the module level: Bluetooth 4.0 single-mode device (BLE only), implemented as a network co-processor controlled by an external host over USB. Unlike standard Bluetooth dongles that rely on the operating system Bluetooth stack, the BLED112 exposes the full BLE controller and GAP/GATT functionality to the application.
Key features include full BLE 4.0 single-mode operation, the Bluegiga BGAPI serial protocol that lets any external host (PC, MCU, LabVIEW) control the stack over USB, the BGScript scripting language for standalone operation, and the Bluegiga Profile Toolkit for rapid custom GATT profile prototyping. The integrated antenna removes RF design effort, and -91 dBm sensitivity supports robust links up to roughly 30 m in line-of-sight conditions.
Architecturally, the BLED112 embeds Silicon Labs (Bluegiga) BLE silicon with on-board flash running the Bluetooth stack, so the host only needs to send BGAPI commands over the USB CDC interface. This bypasses the limitations of native Windows, macOS, and Linux BLE stacks, giving applications full control over GATT communication and BLE advertisements - a key reason it is widely used in test fixtures and instrumentation.
Typical applications include adding BLE connectivity to PCs and embedded hosts for sensor data acquisition, BLE development and profiling with two dongles, LabVIEW-based BLE test systems, and robotics and IoT gateway links.
Design consideration: because the part is end-of-life, plan a migration path early; the BGAPI protocol is shared across the Silicon Labs BLE module family, which eases firmware-level porting even though a mechanical USB-dongle drop-in is scarce.
This page synthesizes distributor availability data, BGAPI ecosystem information, drop-in replacement analysis, and practical design notes not found together in the manufacturer datasheet.

Aplicaciones típicas
BLED112-V1 es adecuado para 6 aplicacións: PC-Based BLE Sensor Data Acquisition, Bluetooth Low Energy Development and Profile Prototyping, LabVIEW-Based BLE Instrumentation and Test Systems, Embedded Host Connectivity (MCU-Controlled BLE), Robotics and IoT Gateway Wireless Links, Medical and Wellness Device Data Capture.
PC-Based BLE Sensor Data Acquisition
The BLED112-V1 turns any Windows, macOS, or Linux PC into a BLE central device by enumerating as a virtual COM port and exposing the full BGAPI command set. Because the on-module stack handles GAP and GATT, host software needs only simple serial commands to scan, connect, and read sensor characteristics - no OS Bluetooth stack dependency. The -91 dBm sensitivity and 30 m range comfortably cover lab-bench and small-facility sensor networks. A quantified benefit: applications retain full advertisement and GATT-server control that native Windows BLE stacks restrict, which is decisive for custom sensor profiles. Trade-off: throughput is capped at the 1 Mbps BLE 4.0 PHY and the USB CDC serial link, so it suits low-rate telemetry rather than bulk streaming.

Bluetooth Low Energy Development and Profile Prototyping
With two BLED112 dongles, developers prototype custom BLE application profiles using the Bluegiga Profile Toolkit and automate on-module logic with BGScript, exactly as specified in the datasheet. One dongle emulates the peripheral advertising custom services while the second acts as the central verifying discovery, read, write, and notify behavior - a complete closed loop on one desk. This avoids spinning custom PCBs during the profile-definition phase and lets GATT tables be iterated in minutes. The 1 Mbps BLE 4.0 PHY matches production-target Silicon Labs modules, so measured link behavior transfers reasonably. Consideration: because the family is EOL, development teams should prototype now and plan the final production module from the current Silicon Labs BLE portfolio.
Recomendado
LabVIEW-Based BLE Instrumentation and Test Systems
The BLED112-V1 is the standard radio for LabVIEW BLE test benches because the MuSAELab BLE Toolkit for LabVIEW implements Silicon Labs BGAPI protocol v1.10 over USB. The dongle's command/response model maps naturally onto LabVIEW VISA serial VIs: scan, connect, discover services, and subscribe to notifications with deterministic timing independent of the Windows Bluetooth stack. This is why production-line BLE fixture builders (wearable testers, heart-rate strap verification, IoT sensor calibration) standardized on the BLED112. The 1 Mbps PHY and -91 dBm sensitivity provide repeatable range behavior across fixtures. Migration risk is real as the part is EOL: teams using the BGAPI-compatible BLED112-V1C or abstracting the serial protocol now will avoid future LabVIEW code rewrites.
Recomendado
Embedded Host Connectivity (MCU-Controlled BLE)
In embedded designs, the BLED112-V1 serves as a network co-processor: a microcontroller drives it over USB using the BGLib ANSI C library, which Silicon Labs documents as portable to ARM Cortex, PIC16/32, and similar architectures. The module carries the entire BLE stack and RF front end, so the host MCU needs only a USB device port and modest memory for the BGAPI parser - a very small footprint per the official BLED112 presentation. The 3.6-5.5 V input accepts standard 5 V USB rail power directly. This architecture shortens time-to-market for adding BLE to legacy industrial controllers. Note the dongle form factor requires a USB-A receptacle in the enclosure; a surface-mount module suits fully integrated products better.
Recomendado
Robotics and IoT Gateway Wireless Links
Hobbyist and light-industrial robotics platforms use the BLED112-V1 as the PC-side radio for BLE motor controllers, sensor hubs, and telemetry links - a pattern visible in BLED112-based robotics adapter products. The dongle's full GATT control lets gateway software manage many peripheral connections, adjust advertisement filtering, and implement custom protocols without OS stack interference. The approximately 30 m range at -91 dBm sensitivity covers typical workshop and arena environments; adding a USB extension cable repositions the radio to escape metal-chassis shadowing. Bandwidth is bounded by the BLE 4.0 1 Mbps PHY, so command/control traffic is ideal while image or bulk-log transfer is not. For gateways requiring many concurrent connections, verify the BGAPI connection limits against your topology.
Recomendado
Medical and Wellness Device Data Capture
BLE health sensors - heart-rate belts, pulse oximeters, glucose meters - commonly advertise standard GATT profiles, and the BLED112-V1 collects their data on any PC by exposing raw GATT access via BGAPI. Full control over scanning and connection parameters yields the deterministic capture intervals medical data-logging applications need, without Bluetooth stack updates silently changing behavior mid-campaign. The -91 dBm sensitivity sustains links across a clinical room, and data volume of typical vitals streams fits easily in the 1 Mbps PHY. Forregulated settings, note that the dongle is a developer component, not a certified medical device; place it in the data-capture PC rather than in patient-coupled hardware. EOL planning applies - qualify the BLED112-V1C as the continuity part in long-duration logging deployments.

Notas de diseño
The BLED112 is end-of-life per Silicon Labs community reports (May 2025). Do not start new production designs around this dongle; existing LabVIEW and BGAPI deployments should qualify the BLED112-V1C as the continuity part and verify BGAPI version behavior on the newer silicon before field rollout. Distributor stock is last-time-buy: secure inventory for the service life of installed test fixtures now, as prices historically rise once EOL stock depletes.
The integrated PCB antenna is directional and is attenuated by metal enclosures. In fixture or gateway designs, use a short USB extension cable to position the dongle outside the metal chassis and away from switching supplies; a 10-30 cm reposition can recover most of the 30 m line-of-sight range. Keep the dongle at least a few centimeters from 2.4 GHz-noisy sources such as WiFi antennas and DC-DC converters to preserve the -91 dBm effective sensitivity in real deployments.
The dongle is bus-powered from the 3.6-5.5 V USB rail and draws its full operating current from the host port. On embedded hosts, confirm the USB VBUS supply meets the 100 mA low-power port guarantee plus margin; on battery-powered gateways, use BGAPI sleep/idle commands between connection events to cut average draw. Avoid unpowered USB hubs whose VBUS droop below the 3.6 V minimum can cause brown-out resets during radio transmit bursts.
