After testing with Michael NA7Q I am pleased to announce that his APRS SMS gateway is now operational for VK Amateurs.
Sending Messages from APRS to SMS
To send a message from APRS to SMS using the following format: @<number> <message>
The @ symbol is followed by the 12 digit destination <number> of the SMS. The words following the destination will be the message.
Example:
To: SMS @61483954895 No cell coverage. Get me on the radio!
Once the message is delivered to the SMS user it will appear as follows: @NA7Q-3 No cell coverage here. Get me on the radio!
Sending from SMS to APRS
To send a message from SMS to APRS, your message to the gateway number should be in the following format: @<callsign> <message>
The @ symbol is followed by the destination <callsign> of the APRS user. The words following the destination will be the message.
Example:
To: 8663524096 @NA7Q-3 Did you forget your cellphone?
Once the message is delivered to the APRS user the message will appear as follows: @61483954895 Did you forget your cellphone?
After a message has been sent to that APRS user, all messages without the callsign prefix will be routed to them unless a message is sent or received from a different callsign.
SMS to APRS Replies
SMS users who reply back to APRS users will still receive their messages if not prefaced with @<callsign>
However, there is no guarantee they will receive it if the system has been updated or restarted.
If the system has been updated or restarted since the last APRS to SMS message, the “last call” log is erased.
So it is encouraged that SMS users preface the message with the destination user!
Example:
To: 61483954895 Did you forget your cellphone?
Once the message is delivered to the APRS user the message will appear as follows: @61483954895 Did you forget your cellphone?
Alias Management
The alias management system uses 12 digits in Australia.
Example:
To: SMS
Add New Alias #alias #add Simon 61424220549
Remove Alias #alias #remove Simon 61424220549
