How to send an SMS with the TC65i? | Telit Cinterion IoT Developer Community

To not to waste modules resources the strategy is to provide the dedicated APIs only for the features to which this will add some value like e.g. better performance. Exchanging text messages is sufficient enough using AT commands that is why there is no dedicated API. You can do it like this: ATCommand atc = new ATCommand(false); // switch to the text mode String at_cmd_response = atc.send("AT+CMGF=1\r"); System.out.println(at_cmd_response); // provide the receiver number at_cmd_response = atc.send("AT+CMGS=\"+48123456789\"\r"); System.out.println(at_cmd_response); // provide the message text & confirm (terminate) at_cmd_response = atc.send("Message \r\n text" + (char) 26); // show the response on the screen System.out.println(at_cmd_response); You can alo check our "How to send the text message" tutorial (it will be available soon).
