2.0.0 stable: Can't connect to AP

[andig]

Trying my working sketch on a new ESP I've noticed that none of my devices are able to connect to ESP when in AP mode (no PSK). Connection simply fails.

Kindly asking for a way here to provide debug information for further diagnosis. Wireless itself is working as station mode if fine when I supply credentials.

can you try staging version?
https://github.com/esp8266/Arduino#staging-version-
the WiFi is reworked in this version, and there is an easy way for debugging too: #1350 (comment)

No luck with staging- compile fails:

Board generic (platform esp8266, package esp8266) is unknown
Error compiling.

Update: moved to #1377

Next stopper: can't compile with Debug->all and Debug Serial->Serial:

However, flashing with DEBUG=none I can connect to the AP now- fine. Should we use this issue to further track rc1 problems?
