Hello guys, I am using the new released Arduino uno wifi rev 2. Upon plugged in I cannot view it's serial port. I am using windows 7 64 bit OS. Regular Arduino Uno board are detected. Hope you can help me guys. Thanks.
Have you installed the core package "Arduino megaAVR Boards" for the board from the IDE ?
Your other repeat post removed btw.
Do I still need to undergo that steps? It is a brand new one. Upon plugged in some drivers not successfully installed. "mEDBG CDC". If yes do you have the procedure. Thanks in advance
Open the IDE
Select Tools / Board /Board Manager
Select Arduino in the first box
Then select Arduino megaAVR Boards
Whilst not always needed you might be better doing that as Administrator and with your security turned OFF.
Also check your DRIVER SIGNING levels in windows. (again not always needed but can stall installations)
Different cores can include additional drivers IIRC
Also moving you to the correct section for this board. 
It works. Thanks a lot for your help.
No problem.
Glad you are up and running.
hi everyone; i think i might have the same issue, but here the thing i have install the board in the board manager and i even can light up an LED. but when i need to use serial communication weird stuff happens. here's my code :
void setup(){
Serial.begin(9600);
Serial.println("hello world");
}
void loop() {
}
so when I open my serial monitor(the one of arduino IDE) and i click the reset button of the arduino I should see hello world (and it is what happens with my UNO) but with the wifi rev2 it writes ????? world and it fails to rewrite hello world. I am at 9600 bauds every where.
Thanks in advance
