Build: Handle WiFi & BT enabled/disabled combos gracefully as possible If using WIFI_INIT_CONFIG_DEFAULT, error message will point out lack of WiFi.

Use IDF_PATH instead of SDK_PATH for the environment variable pointing to esp-idf This will require a matching change in all projects using ESP-IDF. 2016-08-19 02:32:35 -04:00
