- Tue Jun 06, 2017 6:42 am #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

If needed, you can always reflash it back to Espressif firmware at a later time.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

so is it the NONOS 1.5.3(aec24ac9)?
