I'm trying to send the gprs settings via a ota message. I've constructed an xml first and converted it to hex code as described on the OTA_settings_general_7_0 document. After I've add the WDP and WSP headers.
I've opened an account on esendex to test sending the settings, but could not understand how to prepare my binary content for sending. I've tested to send the whole content as below, but the GSM could not understand the message as a setting.
I have also add a TPDU header to my message but nothing has changed.
Do I have to add other headers, or is there a method to send the content smsc?
