ESP32 - setting wrong WiFi password causes crash

[teuteuguy]

When using the mos wifi command with ssid and password and setting password to something incorrect, causes device to crash and core_dump.

Can’t seem to catch the core_dump cause console isn’t active at that point, cause of the mos wifi command

Confirmed, thanks for reporting.

For the record, backtrace from the coredump looks as follows:

Any news in this issue? Does someone know a workaround?

[tripflex]

Yeah this could be a huge deal breakers in moving forward with ESP32 and device provisioning

By "incorrect" do you mean a password that is too short? or that the Station does not accept?
