Receive SMS API
The Receive API feature is implemented in two modes:
1. Non-Polling Mode
2. Polling Mode
Note: By Default, Polling mode is configured.
Non Polling Mode Receive SMS API
Process:
● Upon receipt of an SMS message and based on the configuration, the MultiModem iSMS sends the SMS to the HTTP
or TCP server.
● If the post interval is zero seconds, the MultiModem iSMS uploads the message immediately upon receipt of it. If the
post interval is non-zero, it waits for the configured post interval, queues up the messages, and then uploads the
messages accumulated for the configured post interval.
● The MultiModem iSMS waits for an OK response from the server after sending the SMS to the application through
HTTP or TCP. The response timeout at the MultiModem iSMS is 30 seconds.
