nRF Device Firmware Update vs Switchyard for Railway

The nRF5x Series chips are flash-based SoCs, and as such they represent the most flexible solution available. A key feature of the nRF5x Series and their associated software architecture and S-Series SoftDevices is the possibility for Over-The-Air Device Firmware Upgrade (OTA-DFU) over Bluetooth LE. The DFU application allows to update nRF5 devices using Secure or Legacy DFU bootloader from nRF5 SDK version 4.3 or newer. The firmware should be in .zip file format, prepared using "nrf util" (https://github.com/NordicSemiconductor/pc-nrfutil).

Switchyard is the Railway companion for your phone. Check on your stuff, watch deploys land, and unbreak production from anywhere — without opening your laptop. Not a dashboard replacement. A focused tool for the moments away from your desk when you need to know what's happening — and fix it when it isn't. WHAT YOU GET · Live deploy progress — watch builds and rollouts as they happen · Log tail — chat-style live logs with search and filters, build vs. deploy · Activity feed — every deploy, crash, and alert across all your projects in one place · Spend at a glance — workspace total, projection to end of period, per-project breakdown · Variables — read-only list with copy-to-clipboard · Metrics — CPU, memory, network, and disk sparklines RECOVER FROM ANYWHERE · Rollback to a previous deployment · Redeploy the latest · Restart a service All with the standard iOS confirmation, no scary modals. BUILT LIKE AN IOS APP Native gestures, swipe to refresh, long-press menus, skeleton placeholders, diffable lists. No webview shortcuts.

No pasted account tokens, no servers in the middle. WHAT IT DOESN'T DO (YET) Configuration still belongs on the web — variable editing, settings, custom domain DNS, and project creation deep-link to the dashboard. We're honest about that.
