@paolopastorino My Vanilla Pd prints "bad host? and you do have an error in the [pd connection] sub-patch........ I am surprised that it worked in ios.
you should remove the symbol box and the first message ([connect $1 5001( and just connect the loadbang directly to the [connect 192.168.1.4 5001( message.
I have seen this error a few times lately, and I wonder why?...... where is its origin?
There might be other problems, but I cannot test. Please come back again if that does not solve the problem......
If you want to vary the connection address then you could construct the connect message something like this........ variable_connect.pd
