Transferring files between an S6 and an iPhoned

[Ritmo2k]

I have a friend with whom I need to exchange a large collection of files with. I have an S6 and he has an iPhone. He wears a pretty large tin foil hat and wont install file sharing apps or use Google Drive. Normally, we use WhatsApp or sms, but now we have far to many files to exchange at once to make that reasonable. I have seen apps that I can install on my S6 that allows him to retrieve from my device over wifi without an app, but how can I provide him a means to upload files to me?

Bluetooth file transfer should be possible.
