Hello
I just bought a new Arduino Mega with the Wifi ESP8266 in built in it .
As for test i try uploading the the basic BLINK code from the examples of arduino IDE , but and errors appear as shown below and i have set the control switch 3 and 4 on and the remaining off
`Arduino: 1.8.13 (Windows 7), Board: "Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"
Sketch uses 1536 bytes (0%) of program storage space. Maximum is 253952 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 8183 bytes for local variables. Maximum is 8192 bytes.
An error occurred while uploading the sketch

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
The com3 i used seem to be working for Arduino UNO properly , and the com display arduino uno , but in case of mega the com in the device manager did not even appear
Here are my some personal question arise looking at the errors
1) Should i install arduino ide beta for working this arduino ?
2) Should i have an appropriate USB cable ?
and this is the arduino i bought

I am trying to install the Arduino Beta too
Any suggestion really appreciated , and thanking in advance
With best regard from
