Hi,
With NB-IoT shield on I cant upload any sketch, following error is shown.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
“Show verbose output during compilation”
option enabled in File -> Preferences."

Can you please help

You need to detach the shield before uploading a sketch, as the NB-IoT module shares the same Serial/UART as the one connected to the PC.

I also faced the same problem with my windows 10 system. When I faced that problem at that time thought technical error would be solved after rebooting the system and also updated the system but could not fix the NB-IoT and Ardunio Uno problem also occurred 0xc00007b pop-up error message on my system screen. I was so frustrated with that issue. If anyone has any solution then suggest to me.

@Aston_Roper,

The Arduino UNO only has one Serial.
Remove the shield when you load a new program, after that stick the NB-IoT shield back on top.

I recommend to use a Arduino Board where you have different hardware serials on the USB and on D0/D1.

Best regards,
Jan
