i also have problem compiling IoT example:

/opt/Espressif/crosstool-NG/builds/xtensa-lx106-elf/lib/gcc/xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld: cannot find -lupgrade_ssl

missing upgrade_ssl library i presume. (i don't see it in 0.9.3)

I can't connect to AP using SDK 0.9.3,but same code work fine with 0.9.2 compile.
Just set CWJAP,then restart,hope it auto connect to ap but failed.
Anyone have some suggestion?
Thanks advance!

You need to set bssid_set field to zero when initialising struct station_config.
This field was added in SDK 0.9.3. If not initialised, it will probably be non-zero, and the WiFi stack will try to connect to AP with BSSID equal to bssid field, which also contains garbage if not initialised.
