The answer is yes. I have 2 transmitters and 4 receivers and use them with Nikon flashes and Metz flashes as well as Nissin. They will work with any flash designed to be triggered by Nikon natively.
Thanks Mr. Brucej67 for your explanation.
Meanwhile I wrote an email to service support of godox and I got replied saying as per below in their own words copied & pasted here.
About the questions you mentioned,
Our product X1N can not compatible with NISSIN DI 866 MARK II flash and YONGNUO YN685N.
I suggest that you can choose our flashes,
due to our Godox X system,
all the products can compatible with each other.
And has more brands for Canon,Sony,Fuji,Olympus/Panasonic,
and later will have Pentax etc.
In addition, the Radio Master mode can fire and control the complete Godox 2.4GHz Flash System,
including cross compatibility with Godox 2.4GHz slave strobes for Canon, Nikon, Sony, Olympus/Panasonic, and Fuji.
(that the system is not compatible with the Nissin (Di 866 Mark II) & that of the Yongnuo (Yn 685N) flashes.)
And now,
If the same works well with the above flashes in TTL & Manual mode then I would be happy to buy the same. Kindly recheck and reply, as my purchase depends on the final words you say.
Thanks.
