Tried again today. It didn’t work the first run (same as yesterday, no data on the display). I ended the exercise and reset (power off and power on again). I started the exercise again and… it worked as expected! Everything ok. I ended the exercise. I started a new exercise and… it didn’t work. Reset. I started a new exercise and worked as expected. So, i reset just before the exercise, everything works fine but if i not reset, it doesn’t work. I will send you my log. Thanks.
