The question is, how to get the message reference ID of the SMS, sent using Mobile Broadband API.
On Mobile Broadband API, there is no such status or function to get it, except the reference ID of the request call we make.
If I look at such a request ID, it does not match to the message reference ID I see on the subsequent delivery report message.
The message reference ID, I am talking about here, is the TP-MR parameter in SMS-SUBMIT and SMS-STATUS-REPORT of GSM 03.40 standards specification.
If I instead, use an AT command AT+CMGS, to send SMS over a standard port/modem of the device, I can get the message reference ID from its successful response, and then I can make use of that in matching it to the subsequent delivery report, where the TP-MR will be the part of the PDU of delivery report message. But with Mobile Broadband API call to send SMS, I cannot find a way to get such reference ID. Can somebody help me please?
