Forum Post: Why the context is invisible in sample code

Hi all, I downloaded the  Bluetooth® Low Energy Protocol Stack RL78/G1D applications to communicate with RenesasBLE in the following Renesas webset link: https://www.renesas.com/en-us/software/D3017660.html but when I import the sample project zip file into e2studio version5.0.0.043. I find out I could not see any of code context at all and face the following problem during building process. Description Resource Path Location Type make: *** No rule to make target 'G:/rBLE/src/sample_app/r_vuart_app.c', needed by 'Project_Source/rBLE/src/sample_app/r_vuart_app.obj'. Stop. BLETest C/C++ Problem How to fix these problems? Best Regards, feng
