Flashpoint Zoom (Godox 680) R2 TTL On-Camera Flash - Canon Nikon compatibility

[haring]

I have Canon and Nikon cameras.
Do you think the Nikon version R2 flash unit (as master) will work with the Canon version R2 (as slave) and the Canon version R2 will work as master and the Nikon version R2 as slave?
Can I mix them up and still maintain radio wireless connection and HSS?
Thanks!

Just a warning, as the SLR users here use mostly film: These will only do (pseudo/pre-flash) TTL on Canon respectively Nikon DSLRs! Genuine film TTL was something completely different (and only supported - with considerable side issues limiting its usefulness - on some very early DSLRs).

As to the question in detail: It will depend on whether they talk a Godox proprietary slave protocol - if the Nikon version can slave to Nikon flashes (respectively Canon to Canon) they can hardly be cross-brand compatible.
