mega-20191208 - 2.2.2 or 2.6.2 SDK?

#1 Post by mackowiakp » 09 Dec 2019, 11:46

After compiling (both custom and normal) ver of ESP FW based on mega-20191208 I got something like this:

Code: Select all

[maciek@Piotr normal_ESP8266_4M1M]$ strings firmware.bin|grep "2\.2\.2"
2.2.2-dev(38a443e)
And:

But release notes stands that
[PIO] Update to core 2.6.2
So what ver of SDK is used as default?

There is a difference between "core" version and "SDK" version.

The git repository https://github.com/esp8266/Arduino is using their own version number, which we call "core 2.6.2", based on what they use as version tags.
This "core" library itself uses the Nonos SDK made by Espressif.
At build we decide what SDK we will use, as you can see here: https://github.com/letscontrolit/ESPEas ... #L113-L131

The default we now use is based on core 2.6.2 and SDK set by this define: PIO_FRAMEWORK_ARDUINO_ESPRESSIF_SDK22x_190703.
This version I chose because it is the most stable one with regards to wifi stability.

OK, thank you for the explanation, because I got a little lost in this numbering.

Well then don't start looking at the numbers used in PlatformIO, that will really make you feel lost.
