Overview

CalcAI — First-Time Setup

Follow these steps to unlock, launch, connect Wi‑Fi, and start using CalcAI. Keep your calculator steady for camera autofocus.

Power and batteries

For best results we recommend high-quality AAA lithium batteries (triple‑A). They last longer than standard alkaline cells and handle the higher power draw from the camera and Wi‑Fi modules.

  • Use fresh AAA lithium cells for longest runtime.
  • Camera autofocus and uploads can cause short power spikes; lithium chemistry stays more stable under load.
  • Optional: keep a spare set in your bag. High‑capacity NiMH rechargeables also work, but may need more frequent charging.

  1. On the Home screen, insert the letter P: press ALPHA, then press the key that has P in green (you should see a green P on screen).
  2. Type P>12345 (the > is the STO→ key).

  3. Portal password: configue
  4. Follow the page to add your home Wi‑Fi or hotspot.

Important: Portal lockout behavior

  • While you’re on the Configuration page, the calculator is locked to the portal—you cannot access other calculator functions.
  • Before returning to CALCAI, you must close the portal by tapping “Close configuration portal” on the portal page.
  • If you don’t close it, the calculator won’t function properly.

Camera

  • After you press ENTER to capture, you’ll see “hold still”—that’s autofocus working. Keep the calculator steady.
  • Image quality drops in low light. Use bright, even lighting and avoid glare for best results.

Updates

  • On the calculator: open Settings → Update to check for and install firmware updates.
  • During update, the TI‑84 shows Updating…. The ESP will reboot when finished.
  • After reboot, the ESP automatically re‑sends the CalcAI launcher back to your calculator.
  • We announce new firmware and features in our Discord. Join to get notified.
