title: SSL on SIM800 , certificate select issue
body: <p>I am having some issues while working with SIM800. I am trying to upload SSL certificate but it is not going through. I created a certificate saved it in .cer format. I wrote the certificate in SIM800. I am able to read the content of cer file also. But somehow simcom gave an error when I tried AT+SSLSETCERT. </p>
