#66799 Hi,

which is the SDK inside the ESP8266 Core for Arduino? I asked to the chip with the ESP.getSdkVersion() and ESP.getCoreVersion() and I got : SDK.:1.5.3(aec24ac9) Core.:2_3_0
but I see on the Espressif site that there are multiple version like NONOS or RTOS etc...
Which is the SDK?
Thanks

#66839 When flashing Arduino core, you will be owerwriting the original Espressif firmware, so you will be losing NONOS or RTOS (AT-commands).
If needed, you can always reflash it back to Espressif firmware at a later time.
