Hi

I have an issue with uploading to an ESP8266, I can upload the blink sketch ok and that works fine, but when I do anything to do with Wifi I get the error below :

B4X:
ub Process_Globals
    Public Serial1 As Serial
    Private wifi As ESP8266WiFi
End Sub

Private Sub AppStart
    Serial1.Initialize(115200)
    Log("AppStart")
    If Not(wifi.Connect2("MYSSID","MYPASSWORD")) Then
        Log("Failed to connect to network!")
        Return
    End If
    
End Sub
It starts to upload but then errors :

Any ideas ?

Thanks in advance.

Thanks Erel, the code is as above, no other subs, classes, I will update the Arduino IDE when I get home.
