Thingy91: LTE BLE Gateway with FOTA

Question

Hello,

I am attempting to integrate FOTA (HTTP Application Update) into a Thingy91 project on top of the LTE BLE Gateway example project.

I am on nRF Connect SDK v1.1 (tagged) with the patch provided in the following thread https://devzone.nordicsemi.com/f/nordic-q-a/52689/nrf9160-lte-sensor-gateway-on-thingy-91/217018.

The modem firmware on the Thingy91 is up to date at version 1.0.1.

If I add the following to the bottom of prj.conf:

# Image manager
CONFIG_IMG_MANAGER=y
CONFIG_FLASH=y
CONFIG_IMG_ERASE_PROGRESSIVELY=y

# FOTA library
CONFIG_DOWNLOAD_CLIENT=y
CONFIG_DOWNLOAD_CLIENT_STACK_SIZE=4096
CONFIG_DFU_TARGET=y
CONFIG_FOTA_DOWNLOAD=y

# Application Upgrade support
CONFIG_BOOTLOADER_MCUBOOT=y

# Sample configuration
CONFIG_DOWNLOAD_HOST="s3.amazonaws.com"
CONFIG_DOWNLOAD_FILE="nordic-firmware-files/c1838e44-9d6f-4f41-990e-70b4e60770ce"
CONFIG_APPLICATION_VERSION=1

and update Kconfig with the following:

menu "Application Update (FOTA)"

config DOWNLOAD_HOST
string "Download host name"

config DOWNLOAD_FILE
string "The file to download"

config APPLICATION_VERSION
int "Application version"
default 1

endmenu

the bluetooth will fail to initialize properly.

Thank you for your assistance. Attaching LTE BLE Gateway project with FOTA changes.

For MCUboot, add file nrf9160_pca20035.overlay file to the folder ncs\mcuboot\boot\zephyr

nrf9160_pca20035.overlay

/ {
	chosen {
		zephyr,bt-uart=&uart1;
	};
};

&uart1 {
	current-speed = <1000000>;
	status = "okay";
};

&uart0 {
    rts-pin = <0xFFFFFFFF>;
	cts-pin = <0xFFFFFFFF>;
};

when mcuboot is being compiled, you should see this in the compile log:

-- Using application from 'C:/ncs/mcuboot/boot/zephyr'
Zephyr version: 2.0.99
Changed board to secure nrf9160_pca20035 (NOT NS)
USING OUT OF TREE BOARD
USING OUT OF TREE BOARD
-- Loading C:/ncs/nrf/boards/arm/nrf9160_pca20035/nrf9160_pca20035.dts as base
-- Overlaying C:/ncs/zephyr/dts/common/common.dts
-- Overlaying C:/ncs/mcuboot/boot/zephyr/nrf9160_pca20035.overlay

PS: I added updated "thingy91 support for lte_ble_gateway" patches here.
