WLED-AP doesn't appear

[cipiasentini]

I didn't want to open an issue but I don't know what the problem might be. Im using a lolin nodemcu v3 (clone). I've uploaded the wled00 sketch and with the tool uploaded the Sketch data via Arduino IDE. The firmware flashes correctly, but I get no "WLED-AP" when scanning the APs. Also the blue inboard led stays always on (I don't know if it is supposed to do so). What could be wrong? I append the uploading messages:

You must configure the wled-ap in the sketch or if you don't set the ssid and password in the sketch it will start automatically after a few seconds. The blue led it's all the time on !

After the sketch it's uploading you cand press the reset button to see if everything works.

as said on wiki, the AP could be configured via web. I didn't change anything, I wanted the default WLED-AP access point to appear.

Did you try to delete all flash content? Not only the sketch. Wifi settings are stored there.

What a genius. I had to do that. Thanks man

Thanks @Sceptorrh ! I would not have thought so quickly that some wrong flash data might be the issue! Normally WLED sets a check byte to 233 to see if the settings flash is valid. Still, there is a 1 in 256 chance that the data in that byte is already 233, so WLED could assume that it is a valid save even if it's not.
