A strange mark appears at the lower left of the "~ .c" file in the Project section

Hello!

I am using SDK 15.0.0 with keil.

I tried to use the sample program to do BLE communication, but I have one thing in doubt.

I'm using SDK15 / example / ble_peripheral / ble_app_blinky, but when I open it with keil I get a strange mark.

A strange mark appears at the lower left of the file "~ .c" in the Project field. What does this mean? And what is the solution?

Thank you!

Hi,

I'm not sure I understand what mark you're referring too, but it may be the sign indicating that the you have some unsaved changes in the project. Do you get any compile error when you build the project? 

Best regards

Thank you for reply!

There is no error or warning even if it is compile.

It remains marked after compilation.

Ok, then it has probably nothing to do with the SDK but rather with the IDE. I don't think that it should be a concern.

There was no particular impact!
Don't worry about it!
Thank you very much.
