Bluetooth & BLE

Bluetooth & BLE Solutions

TechNexusGen designs Bluetooth Low Energy (BLE) solutions for IoT devices, wearables, beacons and indoor tracking systems. We engineer BLE hardware around Nordic nRF52/nRF54, Silicon Labs and Espressif silicon, optimizing antennas, power profiles and firmware for maximum range and battery life.

From Bluetooth 5.4 and Auracast broadcast audio to BLE beacons for indoor navigation, we deliver the full stack — PCB, firmware and cross-platform mobile apps in Flutter, React Native and native SDKs. Expect months-to-years of battery life on coin cells.

Frequently asked questions

What is new in Bluetooth 5.4 and Auracast?

Bluetooth 5.4 adds Periodic Advertising with Responses (PAwR) for large bidirectional device fleets and improved Auracast broadcast audio, enabling one source to stream to unlimited receivers.

How long can a BLE device run on a coin cell?

With careful RF and firmware power design, BLE sensors and beacons routinely run for months to years on a single coin cell battery.

Can you build the mobile app too?

Yes. We build cross-platform BLE apps in Flutter and React Native, plus native iOS/Android integration for full control.

Do you support indoor positioning with BLE?

Yes. We build BLE beacon and RTLS systems for indoor navigation, proximity detection and real-time location tracking.
