AI Bluetooth PCB Firmware Development
Budget: $750 – $1,500 USD
I have an AI-integrated PCB that communicates over Bluetooth and is destined for wearable devices. Its core role is automated control of those wearables, with notifications and alerts pushed to the user in real time. I now need the complete embedded firmware plus a lightweight companion app or desktop utility that together unlock all of the board’s capabilities.
On the firmware side, the job covers:
• Integrating the existing AI model so it can run locally for decision making.
• Building a reliable BLE stack: pairing, secure data exchange, and OTA updates.
• Implementing power-saving modes appropriate for wearables.
• Exposing a configurable notifications and alerts framework (vibration, LED, or buzzer depending on the final hardware revision).
Companion software must:
• Provide a simple UI to view status, trigger firmware updates, and adjust alert thresholds.
• Work on at least one platform (Android, iOS, Windows, or macOS)—I’m flexible on which, as long as Bluetooth LE is supported.
Acceptance criteria
1. The board boots, connects over BLE within three seconds, and maintains a stable link for eight hours on a single charge.
2. AI routines execute locally and drive an automated action within 100 ms of the triggering sensor event.
3. Notifications arrive on the companion software with under one-second latency.
4. OTA update completes successfully and the board reboots to the new firmware without manual intervention.
Source code (firmware and companion), build instructions, and a brief usage manual round out the deliverables. If you are comfortable with low-power BLE development and edge AI integration, this should be a straightforward engagement.
