Re: Hello, then I have news that I wanted to share with the galleys "Error compilation" like me,
there is another application of Anton Smirnov named (ArduinoCommander) thanks to ArduinoCommander
I managed to compiled the sketch (demo blink) present in the application, then I put the Uno in factory setting
mode with the sketch (Firmata) also present in the application, there are 3 possibilities Blink demo led 13
Sketch Firmata I have not tried yet, one thing is clear now,
I can compiled from my tablet with ArduinoCommander even if I have not already saved code in my phonebook.
I would have preferred to use Arduinodroid I'm happy for the moment of the result

to finish Great thanks to Anton Smirnov who shares his immense work, it is a genius of electronics, sorry for mistakes because I use a translator, cordially.
