	CommandType  CommandType
	Payload      []byte
	SecurityFlag SecurityFlag
	IV           []byte
	Data         []byte // Encrypted data
}

Packet represents a Tuya BLE packet

func DecryptAndParsePacket

func DecryptAndParsePacket(data []byte, key []byte) (*Packet, error)

DecryptAndParsePacket decrypts and parses a packet from the given data

func NewPacket

func NewPacket(seqNum, responseTo uint32, commandType CommandType, payload []byte, securityFlag SecurityFlag) *Packet

NewPacket creates a new Packet instance

func (*Packet) BuildAndEncryptPacket

func (p *Packet) BuildAndEncryptPacket(key []byte) ([]byte, error)

BuildAndEncryptPacket constructs and encrypts a packet

type SecurityFlag

type SecurityFlag byte

SecurityFlag represents a security flag in the Tuya BLE protocol

const (
	SecurityFlagAuth    SecurityFlag = 0x01
	SecurityFlagLogin   SecurityFlag = 0x04
	SecurityFlagSession SecurityFlag = 0x05
)
