Notice:

AT firmware becomes larger since it supports more functions. So, we provide two firmwares here:

• 1024+1024: Normal AT, which is compiled from ESP8266_NONOS_SDK/examples/at, and uses mbedTLS lib.
• 512+512: Nano AT, which is compiled from ESP8266_NONOS_SDK/examples/at_nano, and uses SSL lib that supports less cipher suites. It is suggested to use normal AT(1024+1024), if your flash size is 2MB or larger.
