# Get ZT3 Wheelie

ZT3 Wheelie is a proprietary Android app (Android 8.0 and later) for a wheelie assist on the Segway-Ninebot ZT3 Pro D. An ESP32 with an MPU6050 motion sensor reads the scooter's tilt 1000 times per second; the app connects to it over Bluetooth LE with a six digit PIN and an encrypted link and shows the attitude as a 3D model, the wheelie angle against an adjustable limit, g-forces and a ten second history. It updates itself from this page. Use on private ground only.

## 1. Find the newest release

`GET https://zt3-pro-wheelie-control.celox.io/latest.json` returns `version`, `published`, `notes` and `assets[]`, each with `target`,
`name`, `url`, `size` (bytes) and `sha256`. It is refreshed from GitHub Releases every 15 minutes. On the
page itself, browsers with WebMCP expose the same data as the tools `get_latest_release`,
`get_download_url` and `get_checksums`.

## 2. Download

- Stable link, always the newest file for the visitor's platform: <https://zt3-pro-wheelie-control.celox.io/download>
- APK: <https://zt3-pro-wheelie-control.celox.io/download/android> — Android 8.0+

## 3. Verify

- The file's SHA-256 must equal the matching `assets[].sha256` in `latest.json`.
- Signing certificate SHA-256: `0e672ef6dc012b6d1824609489db9ce155aecf32a6d881b379b7cb30fe394dde`
- Every release is signed with the same key. Compare with `apksigner verify --print-certs`.

## 4. Install

1. One file for every phone with Android 8.0 or later.
2. Open the file. Android asks once whether your browser may install apps, allow it.
3. Open Devices, search, tap ZT3-Wheelie-XXXX and enter the PIN. Read it once over USB with the command `pin`.

## Limits

- Android only; not on Google Play, distributed as an APK from this page.
- Needs the ZT3 Wheelie controller (ESP32 with MPU6050) running the matching firmware.
- The app shows and configures; it does not limit the throttle yet. That is a later phase of the project.
- Connected only while the app is open; there is no background service.
- Yaw comes from the gyro only and drifts slowly.
- The data stream has 50 lines per second; short impacts between two lines are not shown.
