Hi,I am using a standard GSM/GPRS modem using SIM900A module with Arduino Mega to send data to thingspeak.com as a http client. I am using standard AT command set to to send http packet to thingspeak server on cloud. I wish now to upgrade my client to https protocol since thingspeak supports both http and https (SSL) protocols.Can somebody please help me where to find a modem which has SSL stack built-in?I found a wifi shield (worth $49 or Rs. 5950 in India) which has WiFi 101 library that has SSL feature but I find that a bit expensive for simple application. Has somebody experimented with using any versions of esp8266 with SSL ?Thanks in advance.
