Miscellaneous

KDC200 sends "?" character.

“?” is sent by KDC200 when the device receives undefined character (command) from Host. Application would

ignore “?” character

KDC200 sends one to three leading “NULL” bytes with barcode payload

or packet

KDC200 Bluetooth module goes to sleep mode if not used for a while. KDC200 sends out one to three NULL

bytes to wake up Bluetooth module before sending out barcode payload or packet. Application should ignore

these leading “NULL” bytes.
