Data Validity (Cont.)
To verify data integrity, a 16-bit cyclic redundancy check (CRC) is computed for the
transmitted data and attached to the end of each data packet before transmission. The
receiver will then compute the CRC on all incoming data. Any received data that has an
invalid CRC is discarded.
Glossary
Data Buffer
– Collects incoming serial data prior to over-the-air data transmission. The
data buffer can hold up to 132 bytes at a given time.
