Hello,

I hope someone can help me

Hi LuisFe,
I made the paperbluetooth for that module. And it works as Inizul says. You can see my Ecobot with android, with a range of 15 meters. Ecobot on Vimeo
You dont need to solder pin 34. And also you don't need the jumper J1.
Good luck.

You can download the blueterm code. It's Java, you can modify it with eclipse.
