I'm trying to make a test app that includes sample code from GPS and udp examples.
Building for nRF9160DK with west.
Here's my Kconfig:
```
#
# Copyright (c) 2020 Nordic Semiconductor ASA
#

#
menu "GPS/UDP combined sample"
config GPS_SAMPLE_NMEA_ONLY
bool "Output only NMEA strings"
help
Outputs only NMEA strings from the GPS.
choice GPS_SAMPLE_ANTENNA
default GPS_SAMPLE_ANTENNA_ONBOARD
prompt "Select which antenna to use for GPS"
config GPS_SAMPLE_ANTENNA_ONBOARD
bool "Use onboard antenna"
config GPS_SAMPLE_ANTENNA_EXTERNAL
bool "Use external antenna"
config UDP_DATA_UPLOAD_SIZE_BYTES
int "Number of bytes transmitted to the server"
default 20
config UDP_DATA_UPLOAD_FREQUENCY_SECONDS
int "How often data is transmitted to the server"
default 30
config UDP_PSM_ENABLE
bool "Enable LTE Power Saving Mode"
default y
config UDP_EDRX_ENABLE
bool "Enable LTE enhanced Discontinuous Reception"
config UDP_RAI_ENABLE
bool "Enable LTE Release Assistance Indication"
endmenu
module = UDP
module-str = UDP sample
source "${ZEPHYR_BASE}/subsys/logging/Kconfig.template.log_config"
menu "Zephyr Kernel"
source "Kconfig.zephyr"
endmenu
```
Evidently I need to better understand what west wants to do with Kconfig.
Suggestions please.
