Detailed Description

OpenThread Layer 2 abstraction layer.

Function Documentation

openthread_api_mutex_lock()

void openthread_api_mutex_lock

(

struct openthread_context *

ot_context

)

#include <zephyr/net/openthread.h>

Lock internal mutex before accessing OT API.

OpenThread API is not thread-safe, therefore before accessing any API function, it's needed to lock the internal mutex, to prevent the OpenThread thread from preempting the API call.

Parameters

ot_context

Context to lock.

openthread_api_mutex_try_lock()

int openthread_api_mutex_try_lock

(

struct openthread_context *

ot_context

)

#include <zephyr/net/openthread.h>

Try to lock internal mutex before accessing OT API.

This function behaves like openthread_api_mutex_lock() provided that the internal mutex is unlocked. Otherwise, it exists immediately and returns a negative value.

Parameters

ot_context

Context to lock.

Return values

0	On success.
<0	On failure.

openthread_api_mutex_unlock()

void openthread_api_mutex_unlock

(

struct openthread_context *

ot_context

)

#include <zephyr/net/openthread.h>

Unlock internal mutex after accessing OT API.

Parameters

ot_context

Context to unlock.

openthread_get_default_context()

struct openthread_context * openthread_get_default_context

(

void

)

#include <zephyr/net/openthread.h>

Get pointer to default OpenThread context.

Return values

!NULL	On success.
NULL	On failure.

openthread_get_default_instance()

struct otInstance * openthread_get_default_instance

(

void

)

#include <zephyr/net/openthread.h>

Get pointer to default OpenThread instance.

Return values

!NULL	On success.
NULL	On failure.

openthread_start()

int openthread_start

(

struct openthread_context *

ot_context

)

#include <zephyr/net/openthread.h>

Starts the OpenThread network.

Depends on active settings: it uses stored network configuration, start joining procedure or uses default network configuration. Additionally when the device is MTD, it sets the SED mode to properly attach the network.

Parameters

ot_context

openthread_state_changed_cb_register()

int openthread_state_changed_cb_register	(	struct openthread_context *	ot_context,
		struct openthread_state_changed_cb *	cb
	)

#include <zephyr/net/openthread.h>

Registers callbacks which will be called when certain configuration or state changes occur within OpenThread.

Parameters

ot_context	the OpenThread context to register the callback with.
cb	callback struct to register.

openthread_state_changed_cb_unregister()

int openthread_state_changed_cb_unregister	(	struct openthread_context *	ot_context,
		struct openthread_state_changed_cb *	cb
	)

#include <zephyr/net/openthread.h>

Unregisters OpenThread configuration or state changed callbacks.

Parameters

ot_context	the OpenThread context to unregister the callback from.
cb	callback struct to unregister.

openthread_thread_id_get()

k_tid_t openthread_thread_id_get

(

void

)

#include <zephyr/net/openthread.h>

Get OpenThread thread identification.
