Display leuchtet nicht korrekt: Vermutung kein Wifi

Moin,
ich probiere seit Tagen einen einen Bitcoin WiFi Ticker zu programmieren aber komme leider nicht weiter.
Ich vermute es liegt am WiFi, da ich keine Bestätigung bekomme das ich Internet habe.
SSID und das Passwort sind definitiv richtig eingeben.
Ich bitte um eure Hilfe...

Da ich ein neuer Benutzer bin kann ich die Sketch Datei nicht als Dokument hochladen...

Ich sehe dort nirgends eine Wifi Verbindung, ich wäre euch echt dankbar wenn ihr mir helfen könntet. Tut mir leid das ich den Sketch nicht hochladen kann, so ist es leicht unübersichtlich...

Setze Deinen Code bitte in Codetags [code] davor und [/code] dahinter (ohne *) oder gehe in der IDE auf Bearbeiten - Für Forum kopieren und füge es hier ein.
Das kannst Du auch noch nachträglich ändern.

Bitte den kompletten Code.

Gruß Tommy

Hallo,
dann fang doch erst mal mit einem einfachen Beispiel aus der IDE an. Nur um mal zu sehen ob das Grundsätziche klappt.
Heinz

versuche erst einmal wifi Verbindung mit dem Beispiel aus der Bibliothek herzustellen. Dann implementiere nach und nach dein code da rein. Nicht alles auf einmal, sonst weißt man nicht wo man bugs einbaut.

Zeigst du deine Verbindung im Serial monitor an oder wo? Hast du die richtige Baudrate? Hast du Möglichkeit zum richtigen Router zu verbinden(kein iPhone)? Dann könnstest du sehen, ob ein neues Gerät im Netz ist oder nicht

Hab ich gemacht. Guter Tipp für die Zukunft!

Ja ich habe dies schon mit den einfachsten Codes probiert, jedoch immer das selbe Ergebnis.

Ein Beispiel aus der Bibliothek werde ich gleich nochmal probieren, hatte jedoch damit genauso schlechte Erfahrung gemacht.

Ja die Verbindung zeige ich im Serial Monitor (COM3) an. Baudrate ist auf 9600 und 115200 getestet worden.
Die Verbindung teste ich sonst über mein Wlan Router :TP-Link.., die Verbindung über den iPhone Hotspot war nur ein Test der ebenfalls gleich ausging.

Okey ich bin endlich weitergekommen. Ein Neustart des PC´s hat aus irgendeinem Grund geholfen...
Auf meinem Max7219 erscheint

CONNECTING...
CONNECTED!
Error parsing JSON object.

Was das für ein Problem ist weiß ich noch nicht...
