The (currently latest) firmware version 5.0.52 may cause some SDK functions error, or the console freezing (issue detected in ufr-examples-c-nt4h software). If you are experiencing such a problem, the solution Is to install another firmware version on your device.
If there is on new firmware version available in our firmware update list, we advise the firmware downgrade.
The upgrade or downgrade of the firmware to the 5.0.51 version solves this issue.
