Set/Reset does not seem to work. Anyone have a solution for this?

Hi @physic1st ,

This should be fixed in v1.1.0. Please update and let me know if it resolves your issue.

Previous versions were accidentally always putting the chip into Auto-Set-Reset mode. Performing manual Sets or Resets probably didn't have any effect? Details are here:
