OK, that’s good news. So its probably just a problem with my setup.
I am using TouchOSC version 1.9.11 on iPad.
Under “OSC”, I can set the host, and an outgoing and incoming port (defaults are 1370 and 9000), and it finds host “zynthian ZYNTHIAN OSC”
Under “TouchOSC Bridge” it finds host “zynthian”
There is a green indicator that flashes when it sends data, but I’ve never seen the red indicator (receive?) flash.
Which app are you using on Android?
