Hello there!
I have a big issue trying to connect MBots 1.0 with my phone by bluetooth. I'm using the old way of connecting the robots like into the picture (I've tried also the new one with the servo-motors 1.9 but nothing happened) but there's two bugs encountered.
The first one is that AppInventor can't compile the project (cf at the end of the topic).
The second one is that the app on the mobile crashes when I try to connect to the bluetooth : ("Runtime error : Failed resolution of : Lcom/google/appinventor/components/runtime/util/BluetoothReflection;).
Could you help me please? I've seen only one topic about this but there were no solution to the problem...
First bug :
App Inventor est incapable de compiler ce projet.
