Assume "My Home Wi-Fi" is configured as a DHCP server in range of 192.168.1.*

1 - "iPhone" is connected to "My Home Wi-Fi" and has an assigned IP of 192.168.1.100

2 - Power-on "My Linux Device" running a bonjour ( avahi ) server. "My Linux Device" has *not* joined "My Home Wi-Fi" and has no IP address.

3 - Launch "My iOS App"

4 - "My iOS App" discovers "My Linux Device"

5 - How does "My iOS App" establish a 2-way conenction with "My Linux Device" without disconnecting from "My Home Wi-Fi"

My goal is to establish a 2-way connection between iPhone and "My Linux Device", send a file, then disconenct without forcing the iPhone user to reconnect to "My Home Wi-Fi".

Does the Bonjour device self-assign a 192.168.1.* IP address after ARP'ing to check it is being used or not?

Or are two-way conenctions using some kind of multicast?

Thanks in advance for any clues,

I’m not sure what you’re asking here. Reading the above I can see two interpretations:

You’ve got this working and you’re asking how it works.
You’d like to get this working and you’re asking how you can make it work.

Which is it?
