If your Mimosa C5c is currently running any 1.x or early 2.x firmware (e.g., 2.1.0, 2.3.5), yes, upgrade to 2.8.1 immediately. The performance gains, security patches, and GPS reliability improvements are substantial. Warning: Avoid third-party file hosting sites

However, if you are already running a newer version like 2.9.0 or 3.0.1, do not downgrade to 2.8.1 unless you are experiencing specific bugs introduced in newer releases. Newer firmware versions offer better spectrum analysis tools and support for Mimosa’s cloud management.
