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);

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( afIncomingMSGPac
ket_t *pkt )
