How can I connect two nRF52840 to transfer large data files?

[Gerry]

Hello, Would you have application that can support two nRF52840 pairing and transfer arbitrary large data files?

Thanks, Gerry

That's a very vague question.

Sending a large file is no different, in principle, from sending a small or medium one - it's all just "more of the same"

So what is it, exactly, that you're stuck on?
