Re: what is cyclic redundancy check
CRC check is a way to confirm that data sent was received properly. A simple example would be to send a message that says "hello". The CRC might be the sum of the number of letters which is 5. So you send the message and the CRC, the receiving device gets the message and adds up the sum of the letters and then sends the response. If the CRC response is 5, the message was received properly. If the CRC response is 439 then something went wrong, and the message is sent again until it gets the response of "5" .. That is a very simple example but that is basically sorta how CRC works.
