- Fri Nov 21, 2014 8:47 am #3081 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)

- Tue Nov 25, 2014 9:41 am #3291 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!

- Tue Nov 25, 2014 9:46 am #3294 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.
