softAP(ssid, password) ignores new data and uses old one

[starlino]

I have a weird problem I am basically running this sample witch current rc2.0.0-rc2:
https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/examples/WiFiAccessPoint/WiFiAccessPoint.ino

I have previously used this board with other scripts and somehow the ESP remembers the old SSID/Pass for access point, and ignores the new one

WiFi.softAP(ssid, password);

I tried WiFi.persistent(false); but it did not help.

If I do: Serial.setDebugOutput(true);

I get:

Configuring access point...
softap config unchanged
AP IP address: 192.168.4.1
HTTP server started
scandone
state: 0 -> 2 (b0)
state: 2 -> 3 (0)
state: 3 -> 5 (10)
add 0
aid 5
cnt

So why "softap config unchanged" ? Is there a way I completely reset/zero-out my board to factory defaults ?

An update: switching to rc2.0.0-rc1 fixed the issue above, there might be something wrong in rc2.0.0-rc2,

Duplicate of #1054. Fixed in git now.

@igrr @starlino I have exactly the same problem, but I'm unable to get Arduino to use the latest rc1 version.

I tried following the readme for using Arduino with git version, but installing in the directory did not seem to work ~/Documents/Arduino/hardware/esp8266com. After I re-flashed ESP8266, the SSID for the access point is still the old name.

Ok, I got the 2.4.0-rc1 loaded into Arduino via the Boards Manager by appending https://github.com/esp8266/Arduino/releases/download/2.4.0-rc1/package_esp8266com_index.json:

But the AP still shows the old one even after re-flashing 🤔 Any ideas?

[sayanee]

Alright - I have gotten it to work with the example 👍

Possibly not for the same reasons, but I had an issue that presented the same way: changing the configured SSID/password didn't take effect. It appears that this is what happens when your password isn't at least 8 characters long. Hopefully this keeps someone else from spending a few hours tracking this down...

Thanks!! The thing is as @guruthree says, if password is not 8 chars or more everything is ignored!!

Good grief. That's a couple of hours of my life I won't get back. Is there a fix in the works for that?

Wow what a weird bug! Big thanks @guruthree for saving me a few hours :D
