Project description:
"I’m building a wearable and need someone who can own both sides of the stack: the low-level firmware written in Keil and a companion mobile application that runs smoothly on iOS and Android.

Firmware
embedded code must remain lightweight, responsive, and power-efficient. You will start from a fresh Keil project (ARM Cortex-M0+), implement the drivers sdk , and expose a clean interface for the app to trigger vibration, screen updates, battery level monitoring—whatever the final hardware supports.

Mobile apps
I expect two native builds released through TestFlight and an Android APK (or Play Console track). The apps should pair with the wearable, stream updates in real time, and relay basic settings such as vibration pattern or do-not-disturb windows. Feel free to choose Swift, Kotlin or a cross-platform framework as long as performance and notification handling on both OSs remain first-class.

Real-time link
Continuous, low-latency sync is mandatory. The watch must show an incoming notification within a second of it appearing on the phone and report its acknowledgement status back just as quickly.

Deliverables
• Keil project with fully documented source and compiled HEX
• iOS and Android apps with source, build instructions, and signed test builds
• A short README explaining the over-the-air update procedure and any third-party libraries used
• At least one recorded demo (screen + device) proving end-to-end notification flow

I can provide the hardware reference design, UUID map, and sample packets once we start. Looking forward to working with someone who enjoys jumping between firmware debugging and mobile UI polish alike." (client-provided description)
