🛰️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.

Looking for the best label design for the USB port on Flipper One USB-C1 is the main USB port on Flipper One. It can do all of the following: • Power IN/OUT — it can charge Flipper One and power other devices. • Video OUT — it supports DisplayPort Alt Mode over USB-C so you can connect it to an external monitor. • USB Host + Device — it can emulate USB devices such as Ethernet adapters, mass-storage devices, or serial ports, while also acting as a USB host for connected peripherals. The challenge is to communicate all of this with a single label on the device itself, so users do not have to read the manual. We are trying to make the labeling as clear and compact as possible. This video walks through the constraints we faced, the options we considered, and the trade-offs behind each one. Watch it and let us know what you think. Which label makes the most sense to you? Do you have a better idea? Share it in this GitHub issue:

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:
