Dear Support,

Good morning, I have assembled the STEVAL-ROBKIT1 as described here: https://www.st.com/en/evaluation-tools/steval-robkit1.html

I have followed the assembly instructions as seen here: https://www.youtube.com/watch?v=8fzpv_j343U

When I switched on the robot and paired with my iPhone application the robot doesn't respond to the manual commands.  For example if I only move forward or only turn the direction or a combination nothing happens:

When I move it to the "Follow me" mode it seems to go around in circles and moves at random.  The same also goes when I move it to the "Autopilot" mode.  It seems that one wheel moves more than the other.  I've checked the connections (removed and reconnected).  I have also ensured that nothing is blocking any of the components.  I have also uninstalled and re-installed the application (restarting my mobile phone).  I have also used different locations and also have have ensure that the phone controlling the device is at very close proximity to the robot.  When I go to the diagnostic or debugging screens I see the following:

and then restarting both devices again:

I am using the latest operating system on my phone 26.4.2 (iOS)

I feel that I have exhausted all the troubleshooting I can do on my side.  Please let me know what I can do to debug this further?

Best regards
