Advice on wired ethernet - iPad (TouchOSC) to GP

Thanks for this suggestion, I experimented and it worked. Although it is based on the discussion that @Florian referenced here, I’ll describe my experience if it might help someone else.

Wifi off (not essential) on both MacBook and iPad, with the Lightning cable connecting the two.

TouchOSC Mk1 connections settings on the iPad. There are two settings for Host that work:

  1. Host: the xxxxxx.local using the computer name found in the Shared settings of MacOS system settings.
    Outgoing port: the listening port as specified in GP OSC general settings.
    Incoming port: I used the port assigned automatically in TouchOSC; this could be manually changed.
    Local IP Address: shown as 127.0.0.1(iPad IP-1) and not editable. (this is the default IP when wifi is off for the two iPads I have).

  2. Host: the GP IP address assigned in the GP OSC general settings.
    Outgoing port: (as above)
    Incoming port: (as above)
    Local IP Address: (as above)

GP OSC general settings. There are again two options for the remote client IP address:

  1. The 127.0.0.1(iPad IP-1) from T-OSC connections
  2. The second IP address as described at the link above (iPad IP-2). I was able to find this second one by clicking browse in the connections settings in the T-OSC MkII editor on the MacBook. In my case it was 169.254.106.138.

Conclusion: Either of the two settings in T-OSC work for bi–directional communication, the advantage being that the first does not change after disconnection or reboot. On the GP side only sending to the iPad IP-2 allows for bidirectional communication, the disadvantage being that this one must be discovered and re-entered in GP after disconnection or reboot - not ideal.

Caveat: I use two instances of GP and T-OSC MkI only speaks to one at a time.

Would it be possible to send OSC messages to the first instance and relay them to the second?
