Party Update App The processor used in the Mini can be updated over the air with the help of Nordic Semi’s “nRF Toolbox” app. This app is a free download from the Apple App Store or Google Play Store and is required to complete the update process.
Starting DFU Mode DFU (Device Firmware Upgrade) mode can be activated from the FlightSketch App for altimeters running firmware 27+. Expand the “Settings” menu next to the device name and select “Activate DFU”. The altimeter will re-start and the status LED will stay on indicating DFU mode is active.
Upgrade The Altimeter To start the upgrade process, open the nRF Toolbox app and scroll to the utility services. Select DFU and then tap “Connect” to search for the altimeter. When in DFU mode, the altimeter will broadcast as “DfuTarg”. Tap to select and then browse for the firmware package downloaded earlier from the web. After selecting the firmware to load, the nRF Toolbox app will show “Ready for Update”.
