Dear community,

I have a problem that I can't solve after a lot of research.  :smiley-confuse:

I connected my arduino mega with my genuino yun shield (respecting all the procedure). I can upload sketches, everything works fine.

A problem arises when I try to use the Bridge library's Process class to curl data from a web server and get information on the Linux processor (eg : https://www.arduino.cc/en/Tutorial/Process).

When I upload the sketch on the board, I receive the error message below. The red light "user" lights up.

Code: [Select]

And when I try to print something on the console, I receive this message :

Code: [Select]
Connection impossible: new attempt (1)....
Connection impossible: new attempt (2)....
Connection impossible: new attempt (3)....
Connection impossible: new attempt (4)....
Unable to connect: does the sketch use the bridge?


What should I do ? Is there another way to retrieve information on a web server (txt, php, json)?

Many thanks in advance for your help ! :smiley-draw:
