What can I do to make it work?
For now, I just want to connect to my WiFi.
Tried to google it, but I can't find anyone with a similar problem.

Thanks in advance!

#27979 Do you means you wish to know which AT commands let you connect to another router ?

Do some reading there ... _v0.40.pdf

In short, you need to do an AT+CWMODE=3, then AT+CWLAP to list all APs available around, then you can connect to specific one with AT+CWJAP="MyDLink","MyPassword".

#28514 I don't known why/where this "invalid" comes from, especially that I'm not using AT firmware.
It is probably that saved wifi configs are invalid when trying to do auto-reconnect.
Maybe it will disappear when you will succeed to have your first connection.
