5. GAIA protocol - outlineGAIA: CSR GAIA (Generic Application Interface Architecture) implements an end-to-end, host-agnostic ecosystem supporting host application access to device functionality.Fixed form defined by GAIA protocol:A packet within GAIA form has its parameter in payload given its command form specified with command ID.
6. GAIA protocol - processMobile device: device cipher required information obtained from user interface into GAIA packet, then pass it to Bluetooth board.Board: decipher packet passed from device, then according to the command ID part adopt different methods. Pass corresponding acknowledge packet to device including required message.
