How to bring SMLReader into existing network

[trosenda]

AP Password is the WiFi Password when in AP mode (your device unable to connect to given wifi sssid/passwd)
make sure you enter wifi ssid, wifi password, ap password.
save
powercycle

if it doesnt connect, check your dhcp server or flash the debug and share output of serial console.

@trosenda Thanks for your answer but I'm still missing hints to go further.

1. You explained the usage of AP password but not the syntax. Except minimum 8 characters there is no clear documentation for the necessary types of characters. Or easily say if my used password "ASDFqwer1234" should work.
2. DHCP etc. is double checked by using Tasmota software (everything incl. SSID/PW works fine).
3. Debug output shows:

It looks to me like a bug (see bold lines) that passwords are set but not saved.

Could you please post the debug output after reboot?
Before you edited your message I noticed something like "Wrong config version".
It looks like the Sonoff Basic R3 is driven by an ESP8255 chip.
The library used for configuration (IotWebConf) is using EEPROM for storage, maybe there is an issue with the EEPROM of the ESP8255?
Unfortunately I don't have any ESP8255 device here to test with.

[mruettgers]

"Wrong config version" indicates, that the version of the config in EEPROM does not match the one that has been written previously, or that there is no config found at all.

I added the missed lines to the previous debug output. Sorry for the mess of the font size. I'm sure that you are right concerning 8255. So I cannot use the prefabricated .bin and have to compile.
