My "Hello World" mesh app

Oh. In my testing, I enabled the threading on both the Argon and Xenons on the 5 node mesh network. If anything, I think you want it on the Argon so it doesn’t miss any inbound messages. On the Xenon, I’m not sure what scenarios would cause threading to become a must. If the Argon loses WiFi, for example, then the Argon would miss messages making threading on the Xenon unnecessary I suppose. If you enable on the Argon, I think it makes sense to also enable on the Xenon.
