1 byte, COCO/status byte
Note that the data length specifies the number of bytes of the output format which contains the dataset ID followed by the number of bytes for that dataset. There could be multiple number of datasets per stream.

#define STREAM_PROTOCOL_RESP_DEFAULT_ARRAY_BYTESIZE |
Defines the fixed array size of the response buffer array. The size specified is sufficient for most commands. If a larger size is required, a dynamically allocated buffer is used.
The typical size of the default response array needs to be set to accommodate:
STREAM_PROTOCOL_RESP_MIN_BYTESIZE - minimum response data size STREAM_PROTOCOL_RESP_RESPDATALENGTH_BYTESIZE - needed if there is response data Response data - in most cases one byte. The host command to get trigger bytes uses the default buffer. In this case the number of trigger bytes will be no more than several bytes.
Currently, the only command that requires a dynamically allocated buffer is the CI_CMD_STREAM_GETINFO_STREAM_CONFIG command.
