# Consistent Overhead Byte Stuffing

COBS encoder breaks a packet into one or more sequences of non-zero

bytes.  The encoding routine searches through the first 254 bytes of

the packet looking for the first occurrence of a zero byte.  If no

zero is found, then a code of 0xFF is output, followed by the 254

non-zero bytes. If a zero is found, then the number of bytes

examined, n, is output as the code byte, followed by the actual

values of the (n-1) non-zero bytes up to (but not including) the zero

byte. This process is repeated until all the bytes of the packet have

been encoded.
