The purpose is to add additional platfrom properties that are not supplied to oc_init_platform() function call. This function will likely only be used inside the oc_init_platform_cb_t().

Parameters

[in]	prop	the name of the custom property being added to the platform
[in]	value	the value of the custom property being added to the platform

See also: oc_init_platform_cb_t for example code using this function; oc_init_platform

Typedef Documentation

◆ oc_add_device_cb_t

typedef void(* oc_add_device_cb_t) (void *data)

Callback invoked during oc_add_device().

The purpose is to add any additional device properties that are not supplied to oc_add_device() function call.

Example:

static void set_device_custom_property(void *data)
{
  (void)data;
  oc_set_custom_device_property(purpose, "desk lamp");
}
 
static int app_init(void)
{
  int ret = oc_init_platform("My Platform", NULL, NULL);
  ret |= oc_add_device("/oic/d", "oic.d.light", "My light", "ocf.1.0.0",

◆ oc_connectivity_listening_ports_t

typedef struct oc_connectivity_listening_ports_s oc_connectivity_listening_ports_t

The structure includes flags that can be used to disable listening on certain IP interfaces.

If a port is set to 0, the system will determine which port to open by default. On the other hand, if a port is specified, the stack will open that particular port.

◆ oc_factory_presets_cb_t

typedef void(* oc_factory_presets_cb_t) (size_t device, void *data)

Callback invoked by the stack initialization to perform any "factory settings", e.g., this may be used to load a manufacturer certificate.

The following example illustrates the method of loading a manufacturer certificate chain (end-entity certificate, intermediate CA certificate, and root CA certificate) using oc_pki_xxx APIs.

Example:

void factory_presets_cb(size_t device, void *data)
{
  (void)device;
  (void)data;
#if defined(OC_SECURITY) && defined(OC_PKI)
  char cert[8192];
  size_t cert_len = 8192;
  if (read_pem("pki_certs/ee.pem", cert, &cert_len) < 0) {
    OC_PRINTF("ERROR: unable to read certificates\n");
    return;
  }
 
  char key[4096];
  size_t key_len = 4096;
  if (read_pem("pki_certs/key.pem", key, &key_len) < 0) {
    OC_PRINTF("ERROR: unable to read private key");
    return;
  }
 
  int ee_credid = oc_pki_add_mfg_cert(0, (const unsigned char *)cert,
cert_len, (const unsigned char *)key, key_len);
 
  if (ee_credid < 0) {
    OC_PRINTF("ERROR installing manufacturer EE cert\n");
    return;
  }
 
  cert_len = 8192;
  if (read_pem("pki_certs/subca1.pem", cert, &cert_len) < 0) {
    OC_PRINTF("ERROR: unable to read certificates\n");
    return;
  }
 
  int subca_credid = oc_pki_add_mfg_intermediate_cert(
    0, ee_credid, (const unsigned char *)cert, cert_len);
 
  if (subca_credid < 0) {
    OC_PRINTF("ERROR installing intermediate CA cert\n");
    return;
  }
 
  cert_len = 8192;
  if (read_pem("pki_certs/rootca1.pem", cert, &cert_len) < 0) {
    OC_PRINTF("ERROR: unable to read certificates\n");
    return;
  }
 
  int rootca_credid =
    oc_pki_add_mfg_trust_anchor(0, (const unsigned char *)cert, cert_len);
  if (rootca_credid < 0) {
    OC_PRINTF("ERROR installing root cert\n");
    return;
  }
 
  oc_pki_set_security_profile(0, OC_SP_BLACK, OC_SP_BLACK, ee_credid);
#endif // OC_SECURITY && OC_PKI
}

Parameters

[in]	device	number of the device
[in]	data	context pointer that comes from the oc_set_factory_presets_cb() function

See also: oc_set_factory_presets_cb; oc_pki_add_mfg_cert; oc_pki_add_mfg_intermediate_cert; oc_pki_add_mfg_trust_anchor; oc_pki_set_security_profile

◆ oc_init_platform_cb_t

typedef void(* oc_init_platform_cb_t) (void *data)

Callback invoked during oc_init_platform().

The purpose is to add any additional platform properties that are not supplied to oc_init_platform() function call.

Example:

static void set_additional_platform_properties(void *data)
{
  (void)data;
  // Manufactures Details Link
  oc_set_custom_platform_property(mnml,
"http://www.example.com/manufacture");
  // Model Number
  oc_set_custom_platform_property(mnmo, "Model No1");
  // Date of Manufacture
  oc_set_custom_platform_property(mndt,"2020/01/17");
  //Serial Number
  oc_set_custom_platform_property(mnsel, "1234567890");
}
 
static int app_init(void)
{
  int ret = oc_init_platform("My Platform",
set_additional_platform_properties, NULL); ret |= oc_add_device("/oic/d",
"oic.d.light", "My light", "ocf.1.0.0", "ocf.res.1.0.0", NULL, NULL); return
ret;
}

Parameters

typedef void(* oc_ownership_status_cb_t) (const oc_uuid_t *device_uuid, size_t device_index, bool owned, void *user_data)

Callback invoked when the "owned" property of the doxm is changed.

Parameters

[in]	device_uuid	the UUID of the device that change ownership
[in]	device_index	of the logical device that changed ownership
[in]	owned	if true the device has been claimed by an onboarding tool

typedef void(* oc_random_pin_cb_t) (const unsigned char *pin, size_t pin_len, void *data)

Callback invoked when an onboarding client requests device ownership via the Random PIN Ownership Transfer Method (OTM).

The purpose of the callback is to allow the device to display the random PIN to the user onboarding the device.

Example:

#ifdef OC_SECURITY
static void random_pin_cb(const unsigned char *pin, size_t pin_len, void
*data)

◆ oc_add_device()

int oc_add_device	(	const char *	uri,
		const char *	rt,
		const char *	name,
		const char *	spec_version,
		const char *	data_model_version,
		oc_add_device_cb_t	add_device_cb,
		void *	data
	)

Add an ocf device to the the stack.

This function is typically called as part of the stack initialization process from inside the init callback handler.

The oc_add_device function may be called as many times as needed. Each call will add a new device to the stack with its own port address. Each device is automatically assigned a number starting with zero and incremented by one each time the function is called. This number is not returned therefore it is important to know the order devices are added.

Example:

//app_init is an instance of the `init` callback handler.
static int app_init(void)
{
  int ret = oc_init_platform("Refrigerator", NULL, NULL);
  ret |= oc_add_device("/oic/d", "oic.d.refrigeration", "My fridge",
                       "ocf.2.0.5", "ocf.res.1.0.0,ocf.sh.1.0.0",
                       NULL, NULL);
  ret |= oc_add_device("/oic/d", "oic.d.thermostat", "My thermostat",
                       "ocf.2.0.5", "ocf.res.1.0.0,ocf.sh.1.0.0",
                       NULL, NULL);
  return ret;
}

Parameters

[in]	uri	the The device URI. The wellknown default URI "/oic/d" is hosted by every server. Used to expose device specific information
[in]	rt	the resource type
[in]	name	the user readable name of the device
[in]	spec_version	The version of the OCF Server. This is the "icv" device property
[in]	data_model_version	Spec version of the resource and device specifications to which this device data model is implemtned. This is the "dmv" device property
[in]	add_device_cb	callback function invoked during oc_add_device(). The purpose is to add additional device properties that are not supplied to oc_add_device() function call.
[in]	data	context pointer that is passed to the oc_add_device_cb_t

Returns

0 on success
-1 on failure

See also: init

◆ oc_add_device_v1()

int oc_add_device_v1 ( oc_add_new_device_t cfg )

Add an ocf device to the the stack.

This function is typically called as part of the stack initialization process from inside the init callback handler.

The oc_add_device_v1 function may be called as many times as needed. Each call will add a new device to the stack with its own port address. Each device is automatically assigned a number starting with zero and incremented by one each time the function is called. This number is not returned therefore it is important to know the order devices are added.

Example:

//app_init is an instance of the `init` callback handler.
static int app_init(void)
{
  int ret = oc_init_platform("Refrigerator", NULL, NULL);
  ret |= oc_add_device_v1(device1);
  ret |= oc_add_device_v1(device2);
  return ret;
}

Parameters

[in] cfg the configuration of the new device

Returns

0 on success
-1 on failure

◆ oc_add_ownership_status_cb()

void oc_add_ownership_status_cb	(	oc_ownership_status_cb_t	cb,
		void *	user_data
	)

Add callback that is invoked when the doxm "owned" property is changed.

If oc_add_ownership_status_cb is called before oc_main_init or inside one of the , the oc_handler_t callback funtions the oc_ownership_status_cb_t will be invoked when the stack is initilized giving the startup ownership value. If oc_add_ownership_status_cb is called after oc_main_init the oc_add_ownership_status_cb will not be invoked for the startup ownership value.

Note: Use of this function requires building the stack with OC_SECURITY defined.
