@dimi
I have tested your code several time.
I'm afraid, I found problem.
Soft AP function was operated first time, But When I reset module, It's not possible to access any more. It's always reset when i access M5stack soft AP mode.
I found "Guru Meditation Error" through debugging port.
Please let me know how to fix.
I'm now using WINDOW 10
//====================================================
M5Stack initializing...OK
Guru Meditation Error: Core 0 panic'ed (InstrFetchProhibited). Exception was unhandled.
