I wonder if there's a way to transfer files between flippers without any middlemen (i.e. qFlipper or the mobile app). Maybe using subghz or ir? Would this be possible?

Technically yes but very very impractical

Why impractical?

To follow up, maybe with wifi dev boards or bt?

Bluetooth could work 🤔

File transfer would be reallllly slow
SPI is already slow on Flipper, adding a additional layer would even be slower

Still could be useful for data that's very small. Obviously you won't be syncing large amounts of data, but sending over a few kilobytes of data wouldn't be too bad.

Why did i read kilobytes in that messages as kidneys

Yes, probably have a warning that'll pop up if you try to go above a certain limit

BT do not need any add-on, and it's made for this purpose:-)

If you pipeline it it should only be as slow as the slowest link. And if it goes through SPI even if you use USB or whatnot it shouldn't get any slower right?

Flipper Zero's current radio stack can not act as a host which means Flipper to Flipper communication isn't possible via BT

Is that a hardware or software limitation?

Ok, too bad 😕

Kinda both, the full radio stack can't fit onto flash, and it's a software limitation of the lite stack
I think the best way would be thru SubGhz
Have the receiving end select a folder for received files
And then send each line over subGhz
I can possibly write up a PoC but I don't have a another flipper

My friend just ordered his flipper; once it arrives I'll try to tackle this project

Ah i see that makes sense, thanks for the info ❤️

Yep!

Probably will use something similar to subGhz chat
but it transmits bytes versus text
it will send a START byte
and start all lines with a BEGIN byte and END byte when it reaches the end of the line
and when the file is done it will end with a FINISH byte
probably 0x01 for START
0x02 for BEGIN, 0x03 for END
