BLE Wearable Tracker Design

Job ID: 40027943

Budget: €1,500 – €3,000 EUR

Ultra-Low-Power BLE Tracking Tag — Hardware & Firmware Development

Project Description:
I am developing a brand-new ultra-compact wearable tag that can be attached to keys, bags or personal items and report its position via Bluetooth Low Energy (BLE). The device must provide continuous BLE tracking, local on-device location detection, storage of the “last known location”, and a small acoustic buzzer to help the user find the tag when nearby. Extremely low power consumption is essential so that the battery lasts many months, and the entire device must remain very compact.

Scope (hardware + firmware):

Production-ready schematic (Altium, KiCad or equivalent)

2-layer (or better) PCB files, Gerbers and assembly drawings

Antenna tuning/matching and complete, ordered BOM

Firmware supporting BLE advertising, connection, OTA updates, low-power modes, and beeper control

Tested current-consumption report demonstrating low-power performance

Short bring-up guide for first prototypes

Preferred SoC examples: Nordic nRF52, ESP32-C3 or similar low-power BLE SoC. Open to recommendations if they meet size & power targets.

Please provide: your preferred toolchain, sample projects demonstrating low-energy BLE experience, estimated timeline and fixed price (or milestone breakdown).

Deliverables: source files (schematics, PCB, firmware), Gerbers, BOM, measurement report, and bring-up guide.
