I have a problem, when I tried to send this comand => Comando: AT+SSTRSEND=1,“UPLOAD_PICS_OK”
give me back error 4
I can’t understand… I done this cell.println(“AT+SSTRSEND=1,”"+data+"""); , everything is connected because I can send a comand and then the gprs try to send the comand.
I want to try this:
AT+SDATASEND=1,4<cr> >44454647 <ctrl+z> OK
But I don’t know how to send the and <ctrl+z>
