Topic: using checksum for data integrity (Read 735 times) previous topic - next topic

I have some data that I am sending over a GPRS connection to a server. Data integrity is very important so I am looking to find out what people are typically using as a checksum in Arduino? I found an MD5 library but even the basic example sketch is 14KB. I am using an UNO so that is just to large for me to use. Any suggestions on how to verify data integrity is appreciated.

Do you need error correction, or will you re-send?
