ESP32 HTTPUpdate (FOTA): SSID and pw in NV-memory lost

Projects General Guidance
1

Hello,

I have FOTA update working with ESP32 (HTTPUpdate library) but during FOTA ESP32 looses Wi-Fi SSID and password stored to NV-memory. This is quite inconvenient because then manual action is needed to enter those and to get device back online again.

I use Preferences library to store SSID and password: arduino-esp32/libraries/Preferences at master · espressif/arduino-esp32 · GitHub

Is there some way to preserve SSID and password during FOTA?

Thanks,
Tipo

Unintentionally overwriting data is one thinkable way to ruin data.
