File transfer on 433mhz

Projects Programming

Dear All,

I'm working on a project, where I'd like to transfer files between two arduinos. The file is a raw image file, that will be donwloaded from a server by ftp and then it would be transmitted to the other arduino, that has a TFT display attached.
It would be much cheaper than using a WiFi connection with the arduino.

My idea, is to read and transmit the file bytes by bytes and on the receiver side it would write back to a file on the SD card. Does anybody tried that already?
I'd use some EOF marker also to identify that the file is ended...

I'd like to know if it's possible or if anybody already has a code like this.

Thanks!

A raw (image?) file will take a very long time to transfer via an arduino to any thing even byte by byte. If you are talking about an image file then its real the same as getting and image from a camera. It will just take far to long.

Thanks for the answer... Yes... It would take minutes to transfer a 98kbyte sized file... Ok, I'll use an ethernet shield instead and download it from FTP direct to the display.

Thanks!
