How to update firmware

This guide explains how to update the firmware on your Reach RS3 using the Updater tool in the Emlid Flow app.

Overview

Updater is a tool in Emlid Flow that helps update the firmware on your receiver. Firmware refers to the background program that runs your receiver and requires updates to upgrade the receiver with new features, optimize its performance, and protect it from vulnerabilities.

When an update is available, a red dot will appear next to the Settings icon. The process requires a Wi-Fi connection, regardless of the current connection type.
