In a few hours, Emlid will roll out an update for ReachView 3 that will require Reach Firmware no older than version 26 on a Reach Receiver.
You will need to update your Reach to the latest stable version if you would like to continue using it with ReachView 3 and get all further updates. To update Reach, you can follow: Emlid’s Updater Guide.
This is an important update that will allow Emlid to deploy many more tools on the ReachView 3 app in the future. This particular update will enable the Base Shift feature - learn more about this feature on Emlid’s blog.
