Errors Merging "ble_app_uart" and "twi_sensor"

Question

I found similar questions, but none that were marked as "answered". I have a working version of "nRF5_SDK_160.0.0_98a08e2/examples/ble_peripheral/ble_app_uart". I also have a modified " nRF5_SDK_160.0.0_98a08e2/examples/peripheral/twi_sensor" that works to communicate with my TWI device. I am using Segger IDE. I am attempting to merge the two projects into one by starting from the BLE and added the TWI components. TL;DR Why can't I merge these two projects to get a functional program? In partial merge 1, nothing compiles with error "undefined reference to `nrf_log_backend_uart_init" To fix this, I added more values to emProject and called it partial merge 2. W ithout yet attempting to communicate with the TWI board, everything compiles fine. But when I run the program, I hit "app_error_handler_gcc.c/app_error_handler(ret_code_t error_code, uint32_t line_num, const uint8_t * p_file_name) with error code 0x08. To fix this, I added the final missing parts to the .emProject, which causes the error "'NRF_SUCCESS' undeclared (first use in this function); did you mean 'NRFX_SUCCESS'?" Partial merge 1 means main.c/main.h now initializes the TWI communication as well as handle the nRF52840 UART initialization process. The bluetooth control has been moved to its own file The TWI initialization driver has been added to the " ble_app_uart" from the working "twi_sensor" example the .emProject File has been updated (see "ble_twi-partialMerge1.emProject.txt" since .emProject files won't load) The Nordic drivers are moved into their own file so that the project is kept clean (nRF_files and Segger_files) The missing includes from "twi_sensor" have NOT been added to " ble_app_uart " The sdk_config.h file has been updated with everything from both files (see "sdk_config-ble_only.h" and "sdk_config-twi_added.h") Partial merge 2 means (same as partial 1 except...) .emProject (see "ble_twi-partialMerge2.emProject" since .emProject files won't load) Some of the missing includes from "twi_sensor" HAVE been added to "ble_app_uart" to "" File is added File is added File is added to "" the value "" is added Complete merge means (same as partial 2, except...) .emProject (see " ble_twi-completeMerge.emProject" since .emProject files won't load) All the missing includes from "twi_sensor" HAVE been added to "ble_app_uart" to "configuration/c_preprocessor_definitions" the value "BSP_DEFINES_ONLY;" is added to "configuration/c_user_include_directories" the value "nRF_sdk/components/drivers_nrf/nrf_soc_nosd;" is added Example Code Fullscreen main.c Download /** * Copyright (c) 2014 - 2019, Nordic Semiconductor ASA * * All rights reserved. * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * * 1.

This line right here broke it. It's the 12116 line long sdk_config.h file. When this value was 1, the logging used UART and therefore the BLE can't use it. 
 
 When init_uart was called, it evaluate this if statement in "nrfx_uart.c" to true and set the error code to 0x08. 
 
 EDIT: I also had to remove "BSP_DEFINES_ONLY" and " nRF_sdk/components/drivers_nrf/nrf_soc_nosd"

Errors Merging "ble_app_uart" and "twi_sensor"
