Aleno Smart problem

[Gabrial]

Hello everyone,,
I just bought an Aleno Smart trainer from Decathlon and I need help. I paired it with my eTraining app (Android) via Bluetooth but I cannot get any readings from the trainer. Speed just goes random when I just start pedalling and then drops to 0 or 0.1. No cadence or power readings also.
I tried:
- removing the battery
- swaping the battery with a new one
- installing the app on another phone, thinking mine might not support Bluetooth Smart
No luck so far.

I also tried to calibrate the sensor with the resistance lever, using the procedure found in the manual. Pressed the button until the led light blinked three times, then started pedalling and when I was going over 10kph I began switching resistance levels every 5 seconds. I didn't succeed.
Do I have to keep speed just over 10kph, or can I go as fast as I want?
After I reach level 8 and pedal 5 more seconds, do I stop peddaling? Or I began decresing resistance level?

I was planing on using it with a training app but for now I am pretty disappointed.
Sorry for the long post.

Thank you!
