SMS
The Chameleon CTM-200 gateway has the capability of setting up SMS reports and using SMS commands to
perform general tasks of processing sent and received SMS messages. These SMS messages can be sent to or
received from a carrier’s SMS web portal or a mobile phone.
For more details on the use of SMS with the CTM 200, refer to the
CTM 200 Application Notes
page online at
http://www.cypress.bc.ca/resources/ctm200-application-notes
and click on the ‘SMS Support (an464)’ link
Note: SMS support is dependent on the embedded radio module, carrier and account options; please contact
Cypress Solutions if you have questions regarding SMS functionality
There are two types of SMS commands that the CTM-200 gateway accepts: (1)
$0cmd
- command that does not
require the response to be sent back to the sender and (2)
$1cmd
- command that does require the response to
be sent back to the sender. Both commands can act as a remote management and configuration tool for CTM-
200 gateways.
Any of the CTM-200 commands can be appended after $0/$1 except for the following commands, which are
discarded by the SMS command processor:
cmd event dump
cmd showconfig
cmd factory
No configuration of the CTM-200 is required for it to accept SMS commands
Message format:
$1<ctm command> if the command provides feedback.
$0<ctm command> if the command does not provide feedback.
The first two characters of the message should always be
$0 or $1
. Any of the CTM-200 commands can be
appended after
$0 or $1
except for the commands discarded by the SMS command processor (See list above.).
Moreover, multiple commands separated by
<CR>
or
<CR><LF>
can be sent in a single SMS message\
