Is it true that there's a size limit for files transferred via bluetooth?
 

... I resist the idea that you can't send an arbitrary size file via bluetooth between to devices.

Am I wrong & it's true?

Thanks for any info on the subject!

Well, the file system on mobile phones is usually fat32. Fat32 has a file size limit of 4GiB as I recall.
Some devices, esp. mobile phones, will have arbitrary file size limitations. This is especially likely on older phones with limited ram.
If you really want to know if there are any limits listed in the specifications you'll have to look through them yourself. :)

Thanks for replying, qlue!

I gave an overview to the specs in the link you posted & it looks good, but a little messy.

Kinda like a plate of Spaghetti Bolognaise! :D
