"Initializing ESP module" funktioniert nicht

International Deutsch

Hallo,

ich habe einen Arduino Mega2560 von Makershop mit dem integrierten ESP8266 Wifi. Wenn ich das Test-sketch: WiFiEsp ConnectWPA lade bekomme ich immer diesen Output am Monitor:
[WiFiEsp] Initializing ESP module
[WiFiEsp] >>> TIMEOUT >>>
[WiFiEsp] >>> TIMEOUT >>>
[WiFiEsp] >>> TIMEOUT >>>
[WiFiEsp] >>> TIMEOUT >>>
[WiFiEsp] >>> TIMEOUT >>>
[WiFiEsp] Cannot initialize ESP module
[WiFiEsp] >>> TIMEOUT >>>
[WiFiEsp] No tag found

habt ihr eine Idee woran das liegen kann?

Wahrschinlich an Zeile 42.

Im Ernst, wie sollen wir das ohne Sketch (bitte in Codetags) und ohne einen Link auf das Teil erkennen können?

Gruß Tommy

Hallo,

Sorry; Anbei nun mit mehr Infos:

Arduino Mega2560

/*
 WiFiEsp example: ConnectWPA
 
 This example connects to an encrypted WiFi network using an ESP8266 module.
 Then it prints the  MAC address of the WiFi shield, the IP address obtained
 and other network details.

 For more details see: http://yaab-arduino.blogspot.com/p/wifiesp-example-connect.html
