The AirLink gateway acts as a gateway to send SMS messages from an IP
connected device using AirLink SMS Protocol. The IP device sends a UDP packet
to the AirLink gateway, which then sends the SMS to its destination.
Note: Outgoing SMS messages are limited to 140 characters.
To use AirLink SMS Protocol to send an SMS message from a connected device:
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.
Note: There is no space between the start number and the destination phone number or
between any delimiter and the data fields.
3. Add the field delimiter.
4. Add the data type for the message:
For:
ASCII ASCII
8-bit 8BIT
Unicode UCS-2
Data types are case sensitive.
5. Add another field delimiter.
6. Add the number of ASCII characters in your original message (before it is
converted to ASCII hex format).
7. Add another field delimiter.
8. Add the message to be sent in ASCII hex format. ASCII is case sensitive. Do
not use any punctuation, such as a colon, or characters between hex pairs.
