Terminal

• Open terminal– int open(const char *path, int oflag, option )

• Read/Write data from terminal RX/TX– ssize_t read(int fildes, void *buf, size_t nbyte)– ssize_t write(int fildes, const void *buf, size_t nbyte)

• flush non-transmitted output data, non-read input data, or both– int tcflush(int fildes, int queue_selector)

Socket Setting

• Open socket (raw模式、 raw協定 )– int socket(int domain, int type, int protocol)– socket(PF_INET6, SOCK_RAW,IPPROTO_RAW )

• Set socket(不自動建立 ip header)– int setsockopt(int socket, int level,

int option_name, const void *option_value, socklen_t option_len)

– setsockopt(sockfd, IPPROTO_RAW, IP_HDRINCL, &optval, sizeof(int))

Socket• Send data with a dst addr

– ssize_t sendto(int socket, const void *message, size_t length, int flags, const struct sockaddr *dest_addr, socklen_t dest_len)

• Receive data– ssize_t recvfrom(int socket, void *restrict buffer,

size_t length, int flags, struct sockaddr *restrict address, socklen_t *restrict address_len

• Udp check sum– unsigned int Checksum(unsigned int cksum, void *pBuffer,

unsigned int size)

Pcap

• Find all NIC– int pcap_findalldevs(pcap_if_t **alldevsp, char

*ebuf)

• Open a NIC to capture packet– int pcap_open_live(char *dev, int snaplen, int

promisc, int ms, char *ebuf)

• Check the NIC can be used– int pcap_datalink(pcap_t *p)

Pcap

• Compile the Filter Expressions– int pcap_compile(pcap_t *p, struct bpf_program

*fp, char *str, int optimize, bpf_u_int32 netmask)

• Associate a Filter to a Capture– int pcap_setfilter(pcap_t *p, struct bpf_program

*fp)

• Capture Packets – int pcap_loop(pcap_t *p, int cnt, pcap_handler

callback, u_char *user)

thread

• int pthread_create(pthread_t *pthread, pthread_attr_t *attr, void *(*start_routine) (void *), void *asg);–簡單說明

Install and Compile• Libpcap

– Install Libpcap LibPCAP-Devel• yum install libpcap libpcap-devel

– Compile• gcc expcap.c –l pcap

• Pthread– Compile

• gcc exthread.c –lpthread• Gcc –D_REENTRANT –I/usr/include/nptl ex.c –L/usr/lin/nptl –

lpthread (舊版方式， 2003年以前。在 /usr/inlcude/phtrad.h檔可看日期 )

API-ZigBee-Setting

• Set channel and PANID at tool/8wConfig.cfg– -DDEFAULT_CHANLIST=0x00001000 // 12 - 0x0C– -DZDAPP_CONFIG_PAN_ID=0xABCD

• Set Multicast/Groupcast at nwk_globals.c– _NIB.nwkUseMultiCast = TRUE // Multicast– _NIB.nwkUseMultiCast = FALSE // Groupcast

API-ZigBee-UART

• Set UART parameter at hal_uart.c– uint8 HalUARTOpen(uint8 port, halUARTCfg_t

*config)

• UART read/write– uint16 HalUARTRead(uint8 port, uint8 *buf, uint16

len)– uint16 HalUARTWrite(uint8 port, uint8 *buf,

uint16 len)

API-ZigBee-Group

• Add group for an endpoint at aps_group.h– ZStatus_t aps_AddGroup( uint8 endpoint,

aps_Group_t *group )

• Find a group with endpoint and groupID– aps_Group_t *aps_FindGroup( uint8 endpoint,

uint16 groupID )

• Remove a group with endpoint and groupID– uint8 aps_RemoveGroup( uint8 endpoint, uint16

groupID );

API-ZigBee

• Send RF Data at AF.h– AF_DataRequest( afAddrType_t *dstAddr,

endPointDesc_t *srcEP, uint16 cID, uint16 len, uint8 *buf, uint8 *transID, uint8 options, uint8 radius )

• Data message processor callback– void

SampleApp_MessageMSGCB( afIncomingMSGPacket_t *pkt )
