Communicating with SP90m Using a Mobile Phone
Introduction
The SP90m can receive and process specially formatted
SMS’s causing it to respond accordingly. This functionality
gives you extra flexibility for remote control and monitoring of
your SP90m.
Typically, you will use this functionality if you are operating
your own base/rover system and, being at some distance from
your base, you would like to communicate with it for
monitoring or remote control purposes. The use of SMS’s is
however not restricted to communicating with a base: You can
also use them to communicate with a rover.
SP90m’s SMS functionality may be:
• Disabled
• Set up to process SMS’s only from registered phone
numbers.
• Or set up to process SMS’s from any phone number.
By default, the SP90m accepts SMS’s from any phone number.
Any command you send should be in the form:
(Commands may be typed in using upper- or lower-case characters.)
Any response the remote SP90m returns will be in the form:
Where:
• <sp>: Space character
• {...}: Definition of the parameter you must type (and not
the parameter itself).
• [...]: Parameter required for some commands only.
• Date expressed in day/month/year and time in
hours:minutes:seconds.
• Line in bold characters: Command SMS sent to SP90m
• Line in normal characters: Response SMS from SP90m.
