Unofficial Development Kit for Espressif ESP8266

- Thu Mar 26, 2015 1:13 pm #12681 Hello guys,
I downloaded the latest version and noticed it was still not using Espressif Firmware V1.0 so I copied over the V1.0 SDK but when I compile a project I get this error in the compiler:

Code: Select allc:/Espressif/ESP8266_SDK/lib\libat.a(at_wifiCmd.o): In function `at_setupCmdCipsta':

C:/Espressif/examples/at/Makefile:212: recipe for target 'build/app.out' failed

any ideas ????

I replaced the libat.a with the old one but it flashes the old AT SDK .... v0.21 instead of 0.22

thanks

- Sun Mar 29, 2015 5:53 am #12915 I've downloaded the "esp_iot_sdk_v1.0.0_15_03_20" from espressif site.
I compared and saw that all the lib files are different, why?
