Thanks for using the library.
That's happening either because
- you haven't entered ConfigPortal to input a valid sets of WiFi Credentials which would then be saved into
SaveWiFiCfgFileor - the file has been erased / corrupted between resets (forced format, bad flash,bad power, etc.). I'm afraid only you can deal with this issue.
Pls see the sequence below about how the process is working (actually just tested on a Wemos D1)
- No Config Portal (CP) access and/or without valid input WiFi Credentials. This is what you get at the beginning

HHHHHHH- Check if you accidentally turned on auto format in every startup
#define FORMAT_FILESYSTEM truein the code
// From v1.1.1
// You only need to format the filesystem once
//#define FORMAT_FILESYSTEM true
#define FORMAT_FILESYSTEM false
...
if (FORMAT_FILESYSTEM)
FileFS.format();
// Format FileFS if not yet
#ifdef ESP32
if (!FileFS.begin(true))
#else
if (!FileFS.begin())
#endif
{
Serial.print(FS_Name);
Serial.println(F(" failed! AutoFormatting."));
#ifdef ESP8266
FileFS.format();
#endif
}
If not this case,
- try on other boards or types of boards
- add more debugging messages to see where it's breaking.

Hello, I'm using this board, which I can't perfectly identify. I believe the flash size is 1-2MB, based on the Sketch size %, and since using 4MB flash partitions results in failure to begin either format. esptool.py says
Auto-detected Flash size: 2MB.When I run the example code from Async_ConfigOnSwitch, I see a few things. I've manually censored SSID and password in this serial output:
So it appears that the last known working configuration is recovered from the esp8266 flash. (As detailed here) The file system begins correctly, but
FileFS.open(CONFIG_FILENAME, "r")returnsfalse.Then, I run the config portal and input the wifi info! It saves correctly!
However, if I reset the device, I get the same input for
LoadWifiCfgFileas before.fileis false, and the load fails. I can't figure out why this is.I wrote this separate small sketch which simply reads the config file. If I flash this sketch, instead of resetting the
Async_ConfigOnSwitchsketch, it properly loads the file and prints it with no issue.So it appears to only run into this problem only occurs somewhere during
Async_ConfigOnSwitchwhen starting, strangely. It reproduces on both SPIFFS and LittleFS. I'm not entirely convinced it's not my hardware, to be honest.
