Typedef Documentation

connection_t

typedef struct connection_t connection_t

The struct for holding information about each connection the lwm2m stack uses.

Enumeration Type Documentation

anonymous enum

Enumerator
CIPHERSUITE_COUNT	We only configure one ciphersuite on the client, based on authentication method.
CONPOOL_SIZE	Maximum number of concurrent connections.
LINK_MTU	Maximum Transmission Unit for link.

Function Documentation

connection_create()

connection_t* connection_create	(	otInstance *	aInstance,
		lwm2m_context_t *	lwm2mH,
		lwm2m_object_t *	securityObj,
		int	instanceId
	)

Called from example code directly to create a connection when connecting to a server.

Note that the connection will not be immediately active, and will require some time to resolve hostname and form DTLS connection with the server.

Parameters

aInstance	Openthread Instance pointer
lwm2mH	Wakaama context pointer
securityObj	Pointer to LWM2M security object (to extract creds)
instanceId	Security object instance ID

Returns

Pointer to the connection created, or NULL if error.

connection_free()

void connection_free

(

connection_t *

con

)

Free a connection created with connection_create.

Parameters

con	The connection to free

connection_rx_info_callback()

void connection_rx_info_callback

(

uint16_t

aPktLen

)

Callback that can be implemented by the application to track receive statistics.

Parameters

aPktLen

Length of the received packet

connection_tx_info_callback()

void connection_tx_info_callback

(

uint16_t

aPktLen

)

Callback that can be implemented by the application to track transmit statistics.

Parameters

aPktLen

Length of the received packet
