2.4.2.1.1 Services Provided to a Radio User
Using the built-in text messaging services, a radio user can create, send, receive, store and
display a text message. The following capabilities are included:
• A radio user can create a text message in one of two ways: Quick text or limited free-
form text messages. Quick text messages are pre-defined using CPS. This allows a
user to choose from commonly sent messages without having to retype the content.
Once selected, the user is allowed to edit any part of the Quick text message prior to
sending. The CPS allows you to define 10 Quick Text messages.
• A radio user can select to send a text message to other radios. Messages can be sent to
an individual or to a group. When a message is sent to an individual, the sender
receives an acknowledgement once the recipient receives the message. If all delivery
retry attempts were exhausted, a failure indication will be generated. With messages
addressed to a group, the sender only receives confirmation that the message was
transmitted and does not receive confirmation from any of the intended recipients.
• When receiving a text message, the user is notified of a new message by an icon,
display string, and an audible tone if enabled in the codeplug via the CPS.
• Messages are received only if the radio is currently in digital mode of operation. A radio
user should enter Scan mode to receive messages if multiple channels are being
utilized. System planning considerations associated with data and scan are discussed in
“System Design Considerations” on page 203 of this document.
• A user can store up to 30 received or sent text messages at a time. The user is notified
once the Inbox and sent folder storage becomes full. Once full, subsequent new
messages automatically cause the oldest messages to be deleted. Messages are not
deleted when the radio is turned off.
• A user can store up to 30 draft text messages in the Drafts folder at a time. Once full,
subsequent new drafts automatically cause the oldest draft(s) to be deleted. A user can
opt to Send, Edit, or Delete the drafts in the Drafts folder. The user can opt to Save a text
message that is being written or edited to the Drafts folder. If a high priority event causes
the radio to exit the text message editing screen, the current text message is
automatically saved into the Drafts folder. A draft that is sent is deleted from the Drafts
folder and stored to the Sent folder.
• The user can scroll through messages and select any message to read, reply to,
forward, save or delete.
2.4.2.2 Services Provided to a Third-Party Text Message Application
Motorola provides an Application Development Kit (ADK) which documents how a text message
application interfaces with the text message protocol used for MOTOTRBO. A list of available
ADKs is available on page 134 of this manual.
