On day 3 I successfully uploaded the program and changed my wifi accesspoint name
nanoesp.configWifi(ACCESSPOINT, “MyNanoESP”, “MyPassword”);
And I was able to connect to it, using the specified password. Serial monitor gave successful result.

On day 4 I opened the program and modified the WLAN-name and password in the defines to the new values. But when I upload the program to the board, the D3 led goes on (that’s good), but the serial monitor gives (eventually) “Error, no connection”. Also the WLAN-name is not visible anymore in the available WLAN list (and before uploading it sure was visible).

I have tried this on two computers, both with the same result.
In summary: when I upload the program of day 3, I see the WLAN-name of my NanoESP in the WLAN-list. Then when I upload the program of day 4, the WLAN-name disappears of the WLAN-list.
Does anyone have this problem also? Anyone have a clue how to solve this issue?

Thanks in advance!

Well, this is not a problem or an issue, but this is the goal - what did you expect?!

On day 3 you use the NanoESP as an AP, i.e. your ESP is “a router”.
On day 4, your NanoESP is working as a WLAN Client that should connect to your existing local WLAN Network you provide e.g. via Fritzbox or an equivalent router.

These 2 network modes are totally different and I guess that is the intention of the 2 excercises.
You shoud read carefully the text ;-)

Kacki,

You’ve been a great help. I get “WLAN connected” now. I thought I had to use the name/password combination I’ve entered on day 3, but I should use the name/password of my own local WLAN. Of course!
Note that I’m using the Dutch translation, and the text is not always really clear…
Many thanks for your help!
