Show the full error just like you showed the full sketch (in a < CODE > block)
Your file "Datos.txt" could not be opened. Verify your wiring and the SD card reader has sufficient power.
Well actually if I run the code just with the BMP180 and the SD the code runs perfectly and save the information.

but when I add the GPS code is when all the code dies, so in theory the file "Datos.txt" is working well. I think the problem when I add the GPS code
May be it can be some library? idk
You have found the answer.
Whose theory? Not mine.
so the code doesn't work because the SD card hasn't sufficient powe when I add the GPS?
No, the device does not have sufficient power.
You have proven the SD code works.
ok thanks mate
Yes I did and all went good

When you add devices, verify you have sufficient power to operate them at their maximum value, plus 10%. Your GPS is a power-hungry device.
ok I will prove it
