Calibration problem

[nonino]

Hi. I have a Elite Qubo Digital Smart B+.
I am trying to calibrate it using My e-Training app. I have an Assioma Favero powermeter pedal, which is correctly connected to the app.
However, when using the calibration wizard, when pedalling to get P1 (and keeping the adequate speed of 20km/h), the app stays for minutes in this step, untill I fatigate, without recording P1 or moving to the next step (obtaining P2).
Any ideas?
