Hi @Hbb,
As Sergio mentioned, the latest release for Reach RS+ is 31.3. The latest firmware available for Reach RS is 28.4.
We recommend updating the devices through the Emlid Flow app or Reach Panel which will suggest the most recent updates for your receiver. We don’t have public access to the firmware images on our resources. That’s why it’s always better to check with us regarding the firmware updates and not trust third-party websites.
Once the new firmware release is out, we also post an update on the forum in the News section to keep the users informed. The changelogs are available in our online docs.
