I have created c++ code which sends sms messages. But now I have one problem with smart messages. When I tried to send picture message, phone informs that "Message sending failed". After that I can see my picture message in the outbox. And if i move this message to the Drafts, I can see and send my picture message normally.
Can anyone help me with this problem?
may i ask how you were able to send the picture message? i am also trying to send a picture message. i am able to send an sms but the data is garbled. i am trying to read the ota file by using rfile and then sending it like an ordinary sms. is my code similar to yours? or have you found another way to do this?
