After this the Hexiwear show nothing. After a Hexiwear Reset the LED flash Red for some seconds, then the LED stay with blue light. Nothing to see in the console or on the Hexiwear OLED.

I repeat this steps more than 10 times, but the Hexiwear shows all time the same - NOTHING.

What can i do?

    Hi Peter,

    Thanks for reporting this issue. We replicate this behavior and we found a bug in our FreeRTOS Virtual Machine that will be fixed in our next release.
    In the mean time, you can put a sleep after initialization to solve your issue:
    print("init")
    hexi = hexiwear.HEXIWEAR()
    print("start")
    sleep(1000)
    hexi.fill_screen(0xFFFF,False)

    keep me posted :)
