Good afternoon, I have a problem when connecting to the GPRS network with a cheap SIM800 L I bought on ebay.
After configuring it with the APN of my network provider (do not require a password):
AT+SAPBR=3,1,"Contype","GPRS"
AT+SAPBR=3,1,"APN","internet.nuevatel.com"...
Sim800 supports SSL protocol. AT command "AT+CIPSSL" sets TCP to use SSL function. Module will automatic begin SSL certificate after TCP connected. My Problem: how get SSL certificate? where SSL certificate is save?
