Sending an SMS message

You can send an SMS message by writing the send_message command (with the recipientAddress and payload parameters set properly) to the SMS control object. Because this is a server object, to observe the response, you must force the shell to keep the file descriptor open. In the following example, we use the exec command to do this, then direct the response messages to stderr:

# (exec 3<> /pps/services/cellular/sms/control_private && cat >&3
 && sleep 1 && cat <&3)<<END
> msg::send_message
> id::222
> dat:json:{"recipientAddress":"nnnnnnnnnn", "payload":"Test Message",
    "encoding":"gsm0338"}
> END

Here, nnnnnnnnnn is an actual phone number, including the country code and area code.

If the command is successful, the response is:

@control_private
res::send_message
id::222
dat:json:{"messageId":0}
success:b:true
@control_private
msg::message_status
dat:json:{"messageId":0,"status":"SmsStatusSendSuccess"}

The logging information shows the following:

• Processing of the response by qwf-cellular-services
