ESP32-P4 (C6): WiFi disconnects every 20s and Slave Hosted update fails (404 error)

[marcorogo]

PROBLEM DESCRIPTION

The WiFi connection on my Waveshare ESP32-P4 (C6) is extremely unstable. The device disconnects from the router approximately every 20 seconds, making it impossible to use or manage. This is the second time this issue has appeared.

The "Slave hosted firmware version" is stuck at 0.0.0. I suspect this version mismatch is causing the continuous WiFi drops. When I try to fix it using "Force slave Hosted update", the update fails with a 404 error because the URL is dead.

This is the same issue reported in #711, but it is clearly still present in version 9.14.

TO REPRODUCE

Flash Nuki Hub 9.14 or 9.15 on ESP32-P4.

Go to Advanced Settings.

Enable "Force slave Hosted update on next boot".

Check Serial Log during reboot.

EXPECTED BEHAVIOUR

The system should find the valid hosted firmware binary and flash the ESP32-C6 slave.
