Function Documentation

_i16 sl_NetAppDnsGetHostByName	(	_i8 *	pHostName,
		const _u16	NameLen,
		_u32 *	OutIpAddr,
		const _u8	Family
	)

Get host IP by name
Obtain the IP Address of machine on network, by machine name.

Parameters

[in]	pHostName	Host name
[in]	NameLen	Name length
[out]	OutIpAddr	This parameter is filled in with host IP address. In case that host name is not resolved, out_ip_addr is zero.
[in]	Family	Protocol family

Returns

Zero on success, or negative on failure.
SL_POOL_IS_EMPTY may be return in case there are no resources in the system
In this case try again later or increase MAX_CONCURRENT_ACTIONS Possible DNS error codes:

• SL_NETAPP_DNS_QUERY_NO_RESPONSE
• SL_NETAPP_DNS_NO_SERVER
• SL_NETAPP_DNS_QUERY_FAILED
• SL_NETAPP_DNS_MALFORMED_PACKET
• SL_NETAPP_DNS_MISMATCHED_RESPONSE

See also

Note

Only one sl_NetAppDnsGetHostByName can be handled at a time.
Calling this API while the same command is called from another thread, may result in one of the two scenarios:

1. The command will wait (internal) until the previous command finish, and then be executed.
2. There are not enough resources and POOL_IS_EMPTY error will return.
   In this case, MAX_CONCURRENT_ACTIONS can be increased (result in memory increase) or try again later to issue the command.

Warning

In case an IP address in a string format is set as input, without any prefix (e.g. "1.2.3.4") the device will not try to access the DNS and it will return the input address on the 'out_ip_addr' field

Example

• Getting host by name:

  _u32 DestinationIP;
  _u32 AddrSize;
  _i16 SockId;
  SlSockAddrIn_t Addr;
  
  sl_NetAppDnsGetHostByName("www.google.com", strlen("www.google.com"), &DestinationIP,SL_AF_INET);
  
  Addr.sin_family = SL_AF_INET;
  Addr.sin_port = sl_Htons(80);
  Addr.sin_addr.s_addr = sl_Htonl(DestinationIP);
  AddrSize = sizeof(SlSockAddrIn_t);
  SockId = sl_Socket(SL_AF_INET,SL_SOCK_STREAM, 0);

		const _u8	Family,
		_u32	pAddr[],
		_u32 *	pPort,
		_u16 *	pTextLen,
		_i8 *	pText
	)

Return service attributes like IP address, port and text according to service name
The user sets a service name Full/Part (see example below), and should get:

• IP of service
• The port of service
• The text of service Hence it can make a connection to the specific service and use it. It is similar to sl_NetAppDnsGetHostByName method.
  It is done by a single shot ipv4 & ipv6 (if enabled) query with PTR type on the service name. The command that is sent is from constant parameters and variables parameters.

Parameters

[in]	pServiceName	Service name can be full or partial. Example for full service name: PC1._ipp._tcp.local PC2_server._ftp._tcp.local Example for partial service name: _ipp._tcp.local _ftp._tcp.local
[in]	ServiceLen	The length of the service name (in_pService).
[in]	Family	IPv4 or IPv6 (SL_AF_INET , SL_AF_INET6).
[out]	pAddr	Contains the IP address of the service.
[out]	pPort	Contains the port of the service.
[out]	pTextLen	Has 2 options. One as Input field and the other one as output: Input: Contains the max length of the text that the user wants to get. It means that if the text len of service is bigger that its value than the text is cut to inout_TextLen value. Output: Contain the length of the text that is returned. Can be full text or part of the text (see above).
[out]	pText	Contains the text of the service full or partial

Returns

Zero on success,
SL_POOL_IS_EMPTY may be return in case there are no resources in the system, In this case try again later or increase MAX_CONCURRENT_ACTIONS
In case No service is found error SL_NETAPP_DNS_NO_ANSWER will be returned

See also

sl_NetAppDnsGetHostByName

Note

The returns attributes belongs to the first service found. There may be other services with the same service name that will response to the query. The results of these responses are saved in the peer cache of the Device and should be read by another API.
Only one sl_NetAppDnsGetHostByService can be handled at a time.
Calling this API while the same command is called from another thread, may result in one of the two scenarios:

1. The command will wait (internal) until the previous command finish, and then be executed.
2. There are not enough resources and SL_POOL_IS_EMPTY error will return. In this case, MAX_CONCURRENT_ACTIONS can be increased (result in memory increase) or try again later to issue the command.

Warning

Text length can be 120 bytes only

    is sent by the NWP.

		const _u8	MaxServiceCount,
		const _u8	Flags,
		_i8 *	pBuffer,
		const _u32	BufferLength
	)

Get service list
Insert into out pBuffer a list of peer's services that are in the NWP without issuing any queries (relying on pervious collected data).
The list is in a form of service struct. The user should chose the type of the service struct like:

• Full service parameters with text.
• Full service parameters.
• Short service parameters (port and IP only) especially for tiny hosts.

The different types of struct are made to give the possibility to save memory in the host.
The user can also chose how many max services to get and start point index NWP peer cache.
For example:

1. Get max of 3 full services from index 0.
   • Up to 3 full services from index 0 are inserted into pBuffer (services that are in indexes 0,1,2).
2. Get max of 4 full services from index 3.
   • Up to 4 full services from index 3 are inserted into pBuffer (services that are in indexes 3,4,5,6).
3. Get max of 2 int services from index 6.
   • Up to 2 int services from index 6 are inserted into pBuffer (services that are in indexes 6,7). See below - command parameters.

Parameters

[in]	IndexOffset	- The start index in the peer cache that from it the first service is returned.
[in]	MaxServiceCount	- The Max services that can be returned if existed or if not exceed the max index in the peer cache
[in]	Flags	- an ENUM number that means which service struct to use (means which types of service to fill) use SL_NETAPP_FULL_SERVICE_WITH_TEXT_IPV4_TYPE for SlNetAppGetFullServiceWithTextIpv4List_t use SL_NETAPP_FULL_SERVICE_IPV4_TYPE for SlNetAppGetFullServiceIpv4List_t use SL_NETAPP_SHORT_SERVICE_IPV4_TYP SlNetAppGetShortServiceIpv4List_t use SL_NETAPP_FULL_SERVICE_IPV6_TYPE, SlNetAppGetFullServiceIpv6List_t use SL_NETAPP_SHORT_SERVICE_IPV6_TYPE SlNetAppGetShortServiceIpv6List_t use SL_NETAPP_FULL_SERVICE_WITH_TEXT_IPV6_TYPE SlNetAppGetFullServiceWithTextIpv6List_t
[out]	pBuffer	- The Services are inserted into this buffer. In the struct form according to the bit that is set in the Flags input parameter.
[in]	BufferLength	- The allocated buffer length (pointed by pBuffer).

Returns

ServiceFoundCount - The number of the services that were inserted into the buffer.
Zero means no service is found negative number means an error

If the out pBuffer size is bigger than an RX packet(1480), than an error is returned because there is no place in the RX packet.
The size is a multiply of MaxServiceCount and size of service struct(that is set according to flag value).

Register a new mDNS service
This function registers a new mDNS service to the mDNS package and the DB.
This registered service is a service offered by the application. The service name should be full service name according to RFC of the DNS-SD - meaning the value in name field in the SRV answer.
Example for service name:

1. PC1._ipp._tcp.local
2. PC2_server._ftp._tcp.local

If the option is_unique is set, mDNS probes the service name to make sure it is unique before starting to announce the service on the network. Instance is the instance portion of the service name.

Parameters

[in]	ServiceNameLen	The length of the service.
[in]	TextLen	The length of the service should be smaller than 64.
[in]	Port	The port on this target host port.
[in]	TTL	The TTL of the service
[in]	Options	bitwise parameters: SL_NETAPP_MDNS_OPTIONS_IS_UNIQUE_BIT bit 0 - service is unique per interface (means that the service needs to be unique) SL_NETAPP_MDNS_IPV6_IPV4_SERVICE bit 27 - add this service to IPv6 interface, if exist (default is IPv4 service only) SL_NETAPP_MDNS_IPV6_ONLY_SERVICE bit 28 - add this service to IPv6 interface, but remove it from IPv4 (only IPv6 is available) SL_NETAPP_MDNS_OPTION_UPDATE_TEXT bit 29 - for update text fields (without reregister the service) SL_NETAPP_MDNS_OPTIONS_IS_NOT_PERSISTENT bit 30 - for setting a non persistent service SL_NETAPP_MDNS_OPTIONS_ADD_SERVICE_BIT bit 31 - for internal use if the service should be added or deleted (set means ADD).
[in]	pServiceName	The service name.
[in]	pText	The description of the service. should be as mentioned in the RFC (according to type of the service IPP,FTP...)

Returns

Zero on success, or negative error code on failure

send ICMP ECHO_REQUEST to network hosts

Ping uses the ICMP protocol's mandatory ECHO_REQUEST

Parameters

[in]	pPingParams	Pointer to the ping request structure: If flags parameter is set to 0, ping will report back once all requested pings are done (as defined by TotalNumberOfAttempts). If flags parameter is set to 1, ping will report back after every ping, for TotalNumberOfAttempts. If flags parameter is set to 2, ping will stop after the first successful ping, and report back for the successful ping, as well as any preceding failed ones. If flags parameter is set to 4, for ipv4 - don`t fragment the ping packet. This flag can be set with other flags. For stopping an ongoing ping activity, set parameters IP address to 0
[in]	Family	SL_AF_INET or SL_AF_INET6
[out]	pReport	Ping pReport
[out]	pPingCallback	Callback function upon completion. If callback is NULL, the API is blocked until data arrives

Returns

Zero on success, or negative error code on failure.
SL_POOL_IS_EMPTY may be return in case there are no resources in the system In this case try again later or increase MAX_CONCURRENT_ACTIONS

See also

Note

Only one sl_NetAppPing can be handled at a time. Calling this API while the same command is called from another thread, may result in one of the two scenarios:

1. The command will wait (internal) until the previous command finish, and then be executed.
2. There are not enough resources and SL_POOL_IS_EMPTY error will return. In this case, MAX_CONCURRENT_ACTIONS can be increased (result in memory increase) or try again later to issue the command.

Warning

Example:

• Sending 20 ping requests and reporting results to a callback routine when all requests are sent:

  // callback routine
  void pingRes(SlNetAppPingReport_t* pReport)
  {
  // handle ping results 
  }
        
  // ping activation
  void PingTest()
  {
      SlNetAppPingReport_t report;
      SlNetAppPingCommand_t pingCommand;
           
      pingCommand.Ip = SL_IPV4_VAL(10,1,1,200);     // destination IP address is 10.1.1.200
      pingCommand.PingSize = 150;                   // size of ping, in bytes 
      pingCommand.PingIntervalTime = 100;           // delay between pings, in milliseconds
      pingCommand.PingRequestTimeout = 1000;        // timeout for every ping in milliseconds
      pingCommand.TotalNumberOfAttempts = 20;       // max number of ping requests. 0 - forever 
      pingCommand.Flags = 0;                        // report only when finished
  
      sl_NetAppPing( &pingCommand, SL_AF_INET, &report, pingRes ) ;
  }

Note

Warning

Example

• Setting DHCP Server (AP mode) parameters example:

  SlNetAppDhcpServerBasicOpt_t dhcpParams; 
  _u8 outLen = sizeof(SlNetAppDhcpServerBasicOpt_t); 
  dhcpParams.lease_time      = 4096;                         // lease time (in seconds) of the IP Address
  dhcpParams.ipv4_addr_start =  SL_IPV4_VAL(192,168,1,10);   // first IP Address for allocation. IP Address should be set as Hex number - i.e. 0A0B0C01 for (10.11.12.1)
  dhcpParams.ipv4_addr_last  =  SL_IPV4_VAL(192,168,1,16);   // last IP Address for allocation. IP Address should be set as Hex number - i.e. 0A0B0C01 for (10.11.12.1)
  sl_NetAppStop(SL_NETAPP_DHCP_SERVER_ID);                  // Stop DHCP server before settings
  sl_NetAppSet(SL_NETAPP_DHCP_SERVER_ID, SL_NETAPP_DHCP_SRV_BASIC_OPT, outLen, (_u8* )&dhcpParams);  // set parameters
  sl_NetAppStart(SL_NETAPP_DHCP_SERVER_ID);                 // Start DHCP server with new settings

  
  
• Setting Device URN name:
  Device name, maximum length of 32 characters Device name affects URN name, and WPS file "device name" in WPS I.E (STA-WPS / P2P) In case no device URN name set, the default name is "mysimplelink" In case of setting the device name with length 0, device will return to default name "mysimplelink" Allowed characters in device name are: 'a - z' , 'A - Z' , '0-9' and '-'

  _u8 *my_device = "MY-SIMPLELINK-DEV";
  sl_NetAppSet (SL_NETAPP_DEVICE_ID, SL_NETAPP_DEVICE_URN, strlen(my_device), (_u8 *) my_device);

  
  
• Register new temporary HTTP service name for MDNS (not persistent):

  _u8 *my_http_temp_name = "New - Bonjour Service Name";
  sl_NetAppSet (SL_NETAPP_HTTP_SERVER_ID, SL_NETAPP_HTTP_TEMP_REGISTER_MDNS_SERVICE_NAME, strlen(my_http_temp_name), (_u8 *) my_http_temp_name); 

  
  
• Remove registration of current HTTP internal MDNS service (not persistent) :

  _u8 *old_http_name  = "0800285A7891@mysimplelink-022";
  sl_NetAppSet (SL_NETAPP_HTTP_SERVER_ID, SL_NETAPP_HTTP_TEMP_UNREGISTER_MDNS_SERVICE_NAME, strlen(old_http_name), (_u8 *) old_http_name); 

  
  
• Set DNS client time example:
  Set DNS client (sl_NetAppDnsGetHostByName) timeout, two parameters max_response_time and number_retries. number_retries: Max number of DNS request before sl_NetAppDnsGetHostByName failed, (up to 100 retries). max_response_time: DNS request timeout changed every retry, it`s start with 100 millisecond and increased every retry up to max_response_time milliseconds, (up to 2 seconds)

  SlNetAppDnsClientTime_t time;
  time.MaxResponseTime = 2000;
  time.NumOfRetries = 30;
  sl_NetAppSet (SL_NETAPP_DNS_CLIENT_ID, SL_NETAPP_DNS_CLIENT_TIME, sizeof(time), (_u8 *)&time); 

  
  
• Start MDNS continuous querys:
  In a continuous mDNS query mode, the device keeps sending queries to the network according to a specific service name. The query will be sent in IPv4 and IPv6 (if enabled) format. To see the completed list of responding services sl_NetAppGetServiceList() need to be called

  const signed char AddService[40]            = "Printer._ipp._tcp.local";
  _i16 Status;
  
  Status = sl_NetAppSet(SL_NETAPP_MDNS_ID, SL_NETAPP_MDNS_CONT_QUERY_OPT,strlen(AddService) , &AddService);

  
  
• Stop MDNS:

  Status = sl_NetAppSet(SL_NETAPP_MDNS_ID, SL_NETAPP_MDNS_CONT_QUERY_OPT,0 , 0);

  
  
• Set MDNS timing parameters for service advertisement:
  This option allows to control and reconfigures the timing parameters for service advertisement

  SlNetAppServiceAdvertiseTimingParameters_t Timing;
  _i16 Status;
  
  Timing.t = 200; // 2 seconds
  Timing.p = 2; // 2 repetitions
  Timing.k = 2; // Telescopic factor 2
  Timing.RetransInterval = 0; 
  Timing.Maxinterval = 0xFFFFFFFF;
  Timing.max_time = 5;
  
  Status = sl_NetAppSet(SL_NETAPP_MDNS_ID, SL_NETAPP_MDNS_TIMING_PARAMS_OPT,sizeof(Timing),&Timing);

  
  
• User-defined service types to monitor:
  In cases that the user decides not to get responses from certain types of services it should set the adapt bit in the event mask that is related to:

  // bit 0:  _ipp  
  // bit 1:  _device-info 
  // bit 2:  _http
  // bit 3:  _https
  // bit 4:  _workstation
  // bit 5:  _guid
  // bit 6:  _h323
  // bit 7:  _ntp
  // bit 8:  _objective
  // bit 9:  _rdp
  // bit 10: _remote
  // bit 11: _rtsp
  // bit 12: _sip
  // bit 13: _smb
  // bit 14: _soap
  // bit 15: _ssh
  // bit 16: _telnet
  // bit 17: _tftp
  // bit 18: _xmpp-client
  // bit 19: _raop
  
  
  _u32 EventMask;
  _i16 Status;
  
  EventMask = BIT0 | BIT1 | BIT18;
  Status = sl_NetAppSet(SL_NETAPP_MDNS_ID, SL_NETAPP_MDNS_QEVETN_MASK_OPT,sizeof(EventMask),&EventMask)
