Mbot not sensing obstruction


#1

I m using the make block app on iphone to learn how to code and use mbot (via bluetooth connectivity).

At the 5th level, step number 3 code does not work. Mbot does not sense any obstacles. I have tried to reset it twice, clear the cache and tried to program through our devices but is not sensing obstacles. It is just crashing on the step ‘wait until theres an obstancle’. I and my dad have also upgraded Mbot’s firmware.

Mbot we bought is brand new, 2 weeks ago and the ultrasonic sensor sure looks good.

Can anyone please help?
