imtQueueInit()

void imtQueueInit

(

void

)

Used to initialise both outgoing and incoming queues.

imtQueueMoAdd()

bool imtQueueMoAdd	(	const uint16_t	topic,
		const char *	data,
		const size_t	length
	)

Add an outgoing mobile-originated (MO) message to the queue.

Parameters

topic	Message topic ID.
data	Pointer to the message payload.
length	Message payload length in bytes.

Returns

Bool indicating success or failure to add the message to the queue.

imtQueueMoGetFirst()

imt_t * imtQueueMoGetFirst

(

void

)

Get the address of the head of the MO queue.

Returns

Pointer to the next message in the queue, NULL if queue is empty.

bool imtQueueMoRemove

(

void

)

Remove an outgoing mobile-originated (MO) message from the queue.

Returns

Bool indicating success or failure to remove the message from the queue.

imtQueueMtAdd()

bool imtQueueMtAdd	(	const uint16_t	topic,
		const uint16_t	id,
		const size_t	length
	)

Add an incoming mobile-terminated (MT) message to the queue.

Parameters

topic	Message topic ID.
id	Unique identifier of the message assigned by the modem.
length	Message payload length in bytes.

Returns

Bool indicating success or failure to add the message to the queue.

imt_t * imtQueueMtGetLast

(

void

)

Get the address of the latest message in the MT queue.

Returns

Pointer to the last message in the queue, NULL if queue is empty.

imtQueueMtLock()

void imtQueueMtLock

(

bool

lock

)

Lock or unlock the MT queue to prevent messages from getting discarded if full.

Parameters

lock	Called with true to lock the queue and false to unlock the queue.

Note

This is set to false by default.
