B4R Question WiFi connection: error when compiling

[GiG]

Hi All,

using ESP-01 I'm trying to get a WiFi connection to my router, I'm using this simple code:

Sub Process_Globals
    Public Serial1 As Serial
    Private wifi As ESP8266WiFi
End Sub

Private Sub AppStart
    Serial1.Initialize(115200)
    Log("AppStart")
    If wifi.Connect("legacy") Then
        Log("Connected to router.")
    Else
        Log("Failed to connect to router.")
        Return
    End If

End Sub

When compiling I get this long LOG error:

I'm using 2 libraries: rCore 2.0 and rESP8266WiFi(v1.33)

Arduino version is 1.8.8 and set to board "WeMos D1 R1"

What I'm doing wrong?

Thank you

Can you upload the project (File - export as zip)?

 

[GiG]

Hi,

here is the zip.

I discover that the compiling problem happend if I load rESP8266WiFi library even with a blank code, I mean even without use the library.

With other libraries there are non problems.

 

[Erel]

You should use esp8266 SDK v2.4.2. You are probably using the latest beta version.

 

[GiG]

yes, I was using the last beta, I did, now it's working, thank you!!!

Now they have released v 2.5.0 stable
Will there be support for this version?

Will there be support for this version?

Probably yes.
