WiFi issue with EMX frimware V4.1.5.1

Thanks to mrPositive, we discovered a little bug in the new SPI driver that affects WiFi SPI clock. WiFi will not work with EMX firmware V4.1.5.1 as expected.
We are working on a bug fix and will be available in the next SDK release.

If you need to use WiFi now you need to use firmware V4.1.5.0

Is this message still valid with the new sdk release of today?

No. It should be fixed.
