Hi,
Working on my own project.
Need to have some kind Check of recived data.
Data i have in MCU is stored as Hex. and therfore easy to direct send over Serial.,
However, need some checking, and i need to verify in VB.net and visa versa.
Data can be from 4 to 50 bytes.
Any good examples or solutions ?

Data in MCU is never hexadecimal.
Hexadecimal is an invention by humans.
Data in computers is binary, a collection of zeros and ones.

You are still making the same mistake.

Use a CRC (Cyclic Redundancy Check). They are easy to calculate and good for detecting errors.
