Sending a gateway message
The AirLink device acts as an IP gateway to send non-command SMS messages
(gateway messages) as UDP packets from a locally-connected host to a
configured ALEOS port. The UDP packet must contain the SMS protocol-
formatted message.
Note: Do not use the password with gateway messages. The password is only for use with
SMS commands.
To create an gateway message:
1. Begin with the start field.
2. Follow with the destination phone number. This number must be in the same
format as the phone numbers in the Trusted Phone Number List.
3. Add the field delimiter.
4. Add the message type (ASCII).
5. Add another field delimiter.
6. Add the number of hex characters in your message.
7. Add another field delimiter.
8. Finish with the end field.
Example: You want to send the following message: “Test message” to phone
number (510) 624-4200. To use this feature, convert the message to
hex:54657374206d657373616765. Then format the message as follows:
<<<15106244200,ASCII,12,54657374206d657373616765>>>
where:
· “<<<” is the start delimiter
· “15106244200” is the phone number
· “,” is the delimiter between fields
· “ASCII” is the message type
· “12” is the number of characters in the message
· “54657374206d657373616765” is the message itself
· “>>>” is the end delimiter
Note: The gateway message body MUST be in ASCII hex format. ASCII is case-sensitive.
9. Send the message.
After your message is sent, you receive an ACK message in the format ACK
Field acknowledgment Code ACK Field. For example, if your message was
successfully queued to be sent, you receive the message: ACK0ACK.
If you receive an error message, see SMS on page 383 for details.
