mBot 2.0.2 extension for MIT App Inventor 2

#1

@tec_support

I have spent many days developing a phone app using mBot 2.0.2 extension. The app controls the robot to trace a triangle. So far, it is workable until now. I tried to retrieve some info from some sensors. For a start, I used Lightness sensor as shown below. Got the result 0.0 no matter how brightness shines on the sensor. Nothing changes. What do I go wrong? Where is the document for the extension?

Thank you.

Hi BotCoder,

First, need call the read the light sensor value statement.

The robot will return data when it receives the instruction , the returned data will be returned by the ReceiveLightness C-type statement block
