WiFi.localIP() returns 255.255.255.255 after connect

[SvenArke]

Hardware:

Board: ESP32-WROOM-32
Core Installation version: 1.0.4 & 1.0.5 rc6
IDE name: Arduino 1.8.13

Description:

With 1.0.6 - any version i get always 255.255.255.255 as IP address from WiFi.localIP()

Code:
log_i("Connected to: ");
log_i( "%s", WiFi.SSID() );
log_i( "%s", WiFi.localIP().toString().c_str() );

Core 1.0.4 returns:
[I][Test-2020.ino:85] setup(): Connected to:
[I][Test-2020.ino:86] setup(): NET1
[I][Test-2020.ino:87] setup(): 192.168.0.169

Core 1.0.5 rc1 to rc6 returns:
[I][Test-2020.ino:85] setup(): Connected to:
[I][Test-2020.ino:86] setup(): NET1
[I][Test-2020.ino:87] setup(): 255.255.255.255

Tested all rc versions - no luck. Code runs only on 1.04 flawless. Any suggestions ?

Thank you !

Found the problem !
Sketch contained a bugfix for "hostname not sent via dhcp" - >#2537

WiFi.config(INADDR_NONE, INADDR_NONE, INADDR_NONE);

This kills WiFi.localIP() on Core 1.0.5 rc6 ...

When will the be fixed?

[gerab]

wow, surprisingly it's still there!

Yes, I ran into this bug too. As mention before, no problem if I remove the bugfix for "hostname not sent via dhcp" - >#2537. Is that the final/only solution? Hoping for some words of wisdom from the devs.
