🛰️Satellite modem demo on Flipper One — an emergency pager Experimenting with satellite connectivity on Flipper One. The video shows an emergency SOS pager that sends your geolocation so you can be evacuated from a zombie apocalypse when there is no mobile coverage. NTN (Non-Terrestrial Network) is a 3GPP standard in the LTE/5G family. It uses a regular SIM card and is supported by many modern smartphones and smartwatches. NTN is extremely slow and is billed per byte (!), but this is okay when you need to send tiny amounts of data: telemetry or short messages like “I’m alive, heart rate 80 bpm.” In this demo, we use a Blues Blues NOTE-NGBLWX module that connects to a geostationary satellite on the Skylo Skylo network and transmits data to a Blues NoteHub server. We’re planning to develop a Flipper One IoT module that can serve as a backup communication channel for outdoor use or as an emergency gateway for alarm and monitoring IoT systems.

U-Boot menu now works on Flipper One Now you can choose different kernels and systemd targets before the Linux kernel boots. * It's our LCD/buttons driver plus a slightly modified vanilla U-Boot menu. Will try to upstream it to U-Boot. * This is a temporary solution for testing the selection of different OS profiles. In the final version of Flipper OS, we’ll most likely draw the boot menu using a small program compiled into initramfs, after the kernel has started. But as a temporary solution, it works perfect. * I’m still not happy with the cold boot time: from powering on the processor to having a working menu. Here’s the boot log with timestamps, captured from the processor console: * Our patched U-Boot:
