This is my second attempt at merging a pure UART App (no soft device) into an App derived from the ble_app_template (with soft device)
I see I am not alone in having suffered the app_fifo.h: No such file or directory issue, however none of the remedies described so far have worked for me.
1) using Eclipse on a Mac using sdk_13.0.04a0bfd
2) within the sdk_config.h file APP_UART_ENABLED 1, APP_FIFO_ENABLED 1, RETARGET_ENABLED 1
3) within the Eclipse project nRF5_SDK_13.0.0_04a0bfd/components/libraries/fifo has been added to the list of include directories.
4) my method is to move the additional files in the UART project make file over to the ble_app_template make file in small manageable groups.
I sense this must be an Exclipse issue as nRF5_SDK_13.0.0_04a0bfd/components/libraries/fifo isn't being picked up during compilation
Any ideas?
