Prototype IoT Pet Tracking Band

I’m building a first-run prototype of a smart band that my dog can comfortably wear. The core requirements are clear:

• Location and activity tracking in real time
• Continuous capture of GPS coordinates, movement patterns and basic behavioural stats
• Seamless upload of that data to a mobile app for live map view and activity summaries

Here’s what I need from you:

1. Hardware & Firmware
Design a compact, pet-safe enclosure with a low-power MCU (ESP32, nRF52 or similar), GPS module and motion sensor. Write the embedded code that logs position once per set interval, streams accelerometer data, and packages behavioural metrics for Bluetooth transmission.

2. Companion Mobile App
A simple Android/iOS app (Flutter or React Native is fine) that pairs over BLE, shows the pet’s current location on a map, and graphs daily movement. No cloud back-end is necessary for this phase; local phone storage is acceptable.

3. Documentation
Provide schematics, BOM, firmware source, and instructions so I can replicate or iterate on the build.

Acceptance criteria
• GPS accuracy within ±5 m outdoors
• Minimum 24-hour runtime per charge while logging continuously
• Successful sync and display of all tracked data in the app without crash or lag

If you can turn these requirements into a working prototype quickly and are comfortable refining it in short iterations, I’m ready to coordinate milestones and move forward right away.
