<p>Schedule Send MTM (Message Type Module) allows other MTMs to send messages

at scheduled times. </p>

<p>This tutorial describes how to schedule SMS sending. For instructions on

sending SMS messages, see <xref href="GUID-A2408186-1927-45F4-8972-C9273E5135CF.dita">SMS

<section><title>Required background</title> <p>Before you start, you must

understand: </p> <ul>

<section><title>Introduction</title> <p>Scheduled Send MTM enables you to

do the following tasks: </p> <ul>

<li id="GUID-7BE42BD7-E4BC-586E-987F-2F7AD54EB1AC"><p>Schedule a message to

be sent at a specific scheduled time. </p> </li>

<li id="GUID-E05C56E1-5AB2-50E8-ADD1-F5FEFDA48A3A"><p>Check whether specified

conditions are met before sending a message. </p> </li>

<li id="GUID-18AE81ED-E795-55BD-9796-41AAFA43D021"><p>Resend a message if

an error occurs while sending. </p> </li>

</ul> <p>An SMS service can have configuration settings which control the

scheduled sending of messages. These configuration settings are in four parts: </p> <ul>

<li id="GUID-B3FC8C98-D165-5E7A-B2F5-9D42CDE2807E"><p>If send conditions are

not met (as seen above): The behaviour when this occurs is configured as part

of the send actions. </p> </li>

<li id="GUID-4154A12E-A6D8-5C90-BD0C-AF305BE63BA6"><p>If sending to any recipient

fails: The behaviour in this event is determined by a <xref href="GUID-86A889FA-CF7F-3B67-9D9E-349E3E0155CC.dita"><apiname>SEND_ERROR_ACTIONS</apiname></xref> resource

in the SMS Server MTM resource file (in the device ROM). The resource specifies

the actions that must be taken if errors occur. </p> </li>

</ul><p>Two additional factors can prevent rescheduling occurring: </p><ul>

<li id="GUID-6D141526-EB60-53B3-A734-1477CB4372D7"><p>In order to avoid an

infinite loop of attempting to send a message, which may result in running

the device battery down, a rescheduled message can be limited to a maximum

number of re-tries. If the maximum number of re-tries is reached, then the

message marked as failed and no further retries are attempted. The maximum

number of re-tries is defined in the <xref href="GUID-95828565-7389-381C-BD7E-B7F7B98A2487.dita"><apiname>CMsvSysAgentActions</apiname></xref> error

action. </p> </li>

<li id="GUID-9483768D-B2CA-5616-B789-B6519F5E6826"><p>A timeout can be specified

for waiting for sending conditions to occur. If the timeout occurs before

the conditions are met the pending SMS messages are marked as failed. The

timeout is configurable through the <xref href="GUID-3A9254B7-77C2-300A-9128-6A7BD45F8CBA.dita#GUID-3A9254B7-77C2-300A-9128-6A7BD45F8CBA/GUID-DF0D64F1-5408-335C-8FA8-FE5F874B97E4"><apiname>CMsvScheduleSettings::SetPendingConditionsTimeout()</apiname></xref> function.
