Everything was working great when I was programming with the serial port connected to my windows laptop.
My son pulled out the serial port while an upload was in progress. The upload failed.
But now, when we turn on the mBot, it no longer runs the last program, it seems it has no program.
Worse, when we connect the serial port and try to upload another program, it asks us to connect the serial port, which we’ve already connected.
When I connect through my iPhone app over bluetooth, the connection seems to succeed but the mBot does not respond to any of the commands.
Is there a way to load a default program now?
