crash on AP connection #229

Open MicrodigitElettronica opened 2 years ago

MicrodigitElettronica commented 2 years ago

Hi,

I'm having a very strange (but consistent) crash using iotWebConfig in AP mode as reported below...

The strange fact is that it happens only when the connection comes from Win10 clients... no problems using Android or iOS...

I'm also using Bluetooth Classic (in particular the SPP aka Serial Port Profile) at the same time... and it seems to work even with Win10 if I disable the SPP at all.

I've spent the whole day trying to investigate this crash but with no luck at the moment... and AFAICS the heap seems ok.

Anyone else is experiencing similar issues ?

Best Regards,

          GIampaolo

similar issue here: https://github.com/espressif/arduino-esp32/issues/4222 mitigated (but not resolved in my case) by putting a delay after switching to softAP mode:

WiFi.softAP("XYZ"); delay(2000);
