Firmware update

Update from the browser.
No app needed.

Firmware is installed straight from this page over the Bluetooth connection you already have. Connect the device, open its firmware list and press Update — the image is signed, installed on trial and rolled back automatically if it fails to start.

What makes it safe

The bootloader checks the RSA signature of every image, so nothing but genuine FlyBeeper firmware runs. The new build is installed in test mode and confirms itself only after it has booted — a failed update reverts to the previous firmware on its own.

01
Power on the device
Hold the button until the melody plays. Keep it close to the phone or laptop.
02
Connect from this app
Press Connect and pick your device from the browser''s chooser. No pairing in system settings.
03
Open the firmware list
Devices → your device → Firmware, or the "update available" banner in the header.
04
Press Update
The latest published build is installed over the open connection. Progress runs in percent.
05
Wait for the reboot
The upload takes tens of seconds, then the device restarts and the app reconnects to check what booted.
06
Check the version
The status bar shows the new firmware revision once the device has confirmed the image.
Fallback — iOS Safari

Safari on iOS has no Web Bluetooth at all. Use the Bluefy browser, where this page works as usual — or download the .bin and install it with Nordic's nRF Connect Device Manager.
