GPIO not responding

I have a Raspberry Zero. GPIO works ok with Python. I am trying to do a simple LED on/off with Wolfram/Mathematica, but so far it is not working.

I tried:

In[n]= DeviceWrite["GPIO", 11 -> 1]

to turn on a LED connected to pin 11, but nothing happens. I only get a response

Out[n]= 11 -> 1

I checked previously the GPIO with DeviceOpen["GPIO"] and it responds with: Status: Connected.

I am new with Wolfram. Thank you for any help.
