![]() This method makes that all zero bytes contained in the frame disappear and then only a zero is added at the beginning as (special reserved value) start delimiter of the frame. a chunk containing just a solitary zero byte) or as long as an entire frame.įinally, COBS encodes (replace) each zero-terminated chunk using one COBS code block followed by the chunk non-zero bytes and eliminates the zero byte. A chunk may be as short as one byte (i.e. Every zero-terminated chunk contains one zero byte and it is always at the end of the chunk (trailing zero). Then COBS locates all the zero bytes in the frame (including the added one), and divides the packet at these boundaries into zero-terminated chunks. COBS algorithm first takes its input data and logically appends a single zero byte at the end (it is not necessary that the encoding routine actually adds this zero byte to the end of the packet in the memory, it simply has to behave as if the added zero were there). ![]() In KiNOS stack the special reserved value is 0x00 byte and it is used as UART frame start delimiter.
