This post describes how you can get the ble_app_hrs_freertos example project running in Atollic TrueSTUDIO 8.0 on a pca10040 board. This is a managed make build, it does not rely on the makefile provided by Nordic. No Nordic source files are changed and it even uses the existing gcc linker files from Nordic.
1) Download and install Atollic 8.0
2) Download and unzip nRF_SDK_14.0.0_3bcc1f7.
3) Download the project zip file.
