Pair your mini BT in 30 seconds

Published May 6, 2026

The mini BT speaks Bluetooth LE 5 with the standard Environmental Sensing Service — every modern flight app that supports BLE varios already knows how to talk to it. Pairing is pull-out-the-tab, scan, tap.

First time

  1. Pop the plastic tab out of the battery compartment. The piezo beeps once — that’s hardware ready.
  2. Open your flight app.
  3. In the app’s vario / sensor settings, scan for BLE devices and pick FlyBeeper mini BT from the list.

That’s it. The app will start receiving pressure samples within a second or two.

Per app

  • xcTrack. Settings → Sensors → Bluetooth LE sensor → Scan. Pick the mini BT. xcTrack subscribes to the BLE pressure characteristic and runs its own vario filter on top.

  • SeeYou Navigator. Settings → Sensors → External vario → Bluetooth LE. Pick the mini BT. Pressure and battery percentage show up in the sensor overview.

  • FlySkyHy. iOS only. Settings → Sensors → Bluetooth → Scan. Same drill.

  • xcSoar. Devices → Add → Bluetooth LE → pick the mini BT. xcSoar uses the BLE pressure stream as its airdata source.

Tuning

If the variometer reacts faster than you like — or slower — open the web configurator at config.flybeeper.com. It loads in any Chromium browser, no driver, no install. You can tweak:

  • Climb rate beep curves (every threshold, every frequency)
  • Sink alarm
  • Volume (3 steps + off) and silent-on-ground mode
  • LED climb indicator
  • Auto-off timer

Changes save to the device over Web Bluetooth. No cable, no app store.

When it stops pairing

The mini BT advertises BLE for the first 60 seconds after a battery insert or a button press. If your phone can’t see it, give the front button a quick press — that wakes the radio and restarts advertising.

If you suspect the CR2032 is dead, swap it. A new one runs about €1 and lasts a season of regular flying.
