I want to wirelessly transfer a larger amount of data (camera picture from a Hacrocam) from my arduino mega to my PC (processing). I use XRF modules (XBee like UART <-> RF devices). There are some transmission errors and the XRFs don’t offer any retransmit mechanisms. So I need to implement them myself.
I wonder if someone implemented something like this before and could share its experience and/or code.
I found this link: http://hacromatic.com/blog/2012/08/make-your-serial-protocol-robust-with-8-bit-crc-codes/ which might be a good start.
