virtual nsapi_error_t delete_all_messages ( )

pure virtual

Deletes all messages from the currently set memory/SIM.

Returns: NSAPI_ERROR_OK on success NSAPI_ERROR_DEVICE_ERROR on failure

Implemented in AT_CellularSMS.

virtual nsapi_size_or_error_t get_sms	(	char *	buf,
		uint16_t	buf_len,
		char *	phone_num,
		uint16_t	phone_len,
		char *	time_stamp,
		uint16_t	time_len,
		int *	buf_size
	)

pure virtual

Gets the oldest received sms.

Parameters

buf	preallocated buffer for SMS message content
buf_len	length of allocated buf
phone_num	preallocated buffer for phone number where SMS was sent
phone_len	length of allocated phone_num buffer
time_stamp	preallocated buffer for TP-Service Centre Time Stamp (format: yy/MM/dd,hh:mm:ss-+zz). +-zz is timezone. The unit of time zone is a quarter of an hour relative to GMT. For example +32 would be GMT+8.
time_len	length of allocated time_stamp buffer
buf_size	if method return error NSAPI_ERROR_NO_MEMORY because the given buf was not big enough, this holds the size which is enough. Otherwise zero.

Returns: On success, length of the received SMS, (length of the buf, positive value) NSAPI_ERROR_PARAMETER if invalid parameters NSAPI_ERROR_NO_MEMORY on memory failure SMS_ERROR_MULTIPART_ALL_PARTS_NOT_READ if SMS was multipart but not all parts are present/failed to read. -1 if no SMS was found NSAPI_ERROR_DEVICE_ERROR on other failures

Implemented in AT_CellularSMS.

virtual nsapi_error_t initialize ( CellularSMSMmode mode )

pure virtual

Does all the necessary initializations needed for receiving and sending SMS.

Parameters

mode	enumeration for choosing the correct mode: text/pdu

Returns: NSAPI_ERROR_OK on success NSAPI_ERROR_NO_MEMORY on memory failure NSAPI_ERROR_DEVICE_ERROR on other failures

virtual nsapi_size_or_error_t send_sms	(	const char *	phone_number,
		const char *	message,
		int	msg_len
	)

pure virtual

Send the SMS with the given parameters.

Parameters

phone_number	Phone number where to send SMS
message	SMS message content
msg_len	Length of the message

Returns: On success, length of the sent SMS (positive value) NSAPI_ERROR_PARAMETER if invalid parameters NSAPI_ERROR_NO_MEMORY on memory failure NSAPI_ERROR_DEVICE_ERROR on other failures

Implemented in AT_CellularSMS.

virtual nsapi_error_t set_cpms	(	const char *	memr,
		const char *	memw,
		const char *	mems
	)

pure virtual

CPMS preferred message storage.

Parameters

memr	memory from which messages are read and deleted "SM" - SIM SMS memory storage (default) "ME" - NVM SMS storage
memw	memory to which writing and sending operations are made "SM" - SIM SMS memory storage (default) "ME" - NVM SMS storage
mems	memory to which received SMs are preferred to be stored "SM" - SIM SMS memory storage (default) "ME" - NVM SMS storage

Returns: NSAPI_ERROR_OK on success NSAPI_ERROR_DEVICE_ERROR on failure

Implemented in AT_CellularSMS.

virtual nsapi_error_t set_csca	(	const char *	sca,
		int	type
	)

pure virtual

CSCA - set Service Center Address.

Parameters

sca	Service Center Address to be used for mobile originated SMS transmissions.
type	129 - national numbering scheme, 145 - international numbering scheme (contains the character "+")

Returns: NSAPI_ERROR_OK on success NSAPI_ERROR_DEVICE_ERROR on failure

Implemented in AT_CellularSMS.

virtual nsapi_size_or_error_t set_cscs ( const char * chr_set )

pure virtual

Set command sets the current character set used by the device.

"GSM", "IRA",....

Remarks: Current implementation support only ASCII so choose the correct character set.

Parameters

chr_set preferred character set list (comma separated). Modem might not support the wanted character set, so chr_set list is looped from start until supported set is found. Used character set index is returned. See more from 3GPP TS 27.005.

Returns: Used character set index from the given list in case of success. NSAPI_ERROR_DEVICE_ERROR on failure

Implemented in AT_CellularSMS.

virtual void set_extra_sim_wait_time ( int sim_wait_time )

pure virtual

Some modems need extra time between AT commands and responses, or there will be error -314, SIM busy.

If SIM busy errors are an issue, this time should be increased. It can also be set to zero to make operations faster and more energy efficient if no errors will follow. By default, wait time is zero.

Parameters

sim_wait_time

Implemented in AT_CellularSMS.

virtual void set_sms_callback ( Callback< void()> func )

pure virtual

Callback that is called when new SMS is received.

SMS can be fetched using method get_sms().

Remarks: In PDU mode, there can be multipart SMS, and callback is called for every received part.

Parameters

func	Callback function that is called when new SMS is received.

Implemented in AT_CellularSMS.
