We’re about to deploy several LX40s in an environment where Wi-Fi is not allowed. I was happy to see that it’s disabled by default; when disabled, is the Wi-Fi radio completely powered down and thus safe to run without that antenna attached? We may want to use this functionality in future deployments so I really don’t want to fry that radio. Many thanks!
