If you turn off the serial interface and subsequently lose WiFi connection to the BERNINA WiFi Device, the only way to reconfigure it is to perform a ‘hard reset’.
1Plug the device into your computer and insert a hairpin into the Reset aperture on the side. The device state indicator turns white to show that reset has started.
2Hold for 10 seconds. This restores the device to whatever firmware it was initially programmed with.
The BERNINA WiFi Device can then be reconfigured using BERNINA WiFi Connector.
