Hello,
I'm following this documentation Doc to include Fota upgrade on peripheral LBS sample but I have the following problems:
1) all file .bin like (app_update.bin, app_to_sign.bin ecc) are not generated when i build the application. Here below my project.conf
CONFIG_NCS_SAMPLES_DEFAULTS=y
CONFIG_BT=y
CONFIG_BT_PERIPHERAL=y
CONFIG_BT_DEVICE_NAME="Nordic_LBS"
# Enable the LBS service
CONFIG_BT_LBS=y
# Enable Battery service and HeartRate
CONFIG_BT_BAS=y
CONFIG_BT_HRS=y
# For FOTA
CONFIG_BOOTLOADER_MCUBOOT=y
CONFIG_MCUMGR=y
CONFIG_MCUMGR_CMD_OS_MGMT=y
CONFIG_MCUMGR_CMD_IMG_MGMT=y
CONFIG_MCUMGR_SMP_BT=y
CONFIG_IMG_ERASE_PROGRESSIVELY=y
CONFIG_MCUMGR_SMP_BT_AUTHEN=n # n=disables the pairing requirement with mobile device
CONFIG_BT_LBS_POLL_BUTTON=y
CONFIG_DK_LIBRARY=y
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048
2) I have founded .bin file in the following link Bin file , but when i try to upload that file to my NRF52840 DK a have this error: "DFU characteristic not founded", but SMP service and characteristic are visibile with nrf Connect Android app.
From that link you can see the error: Video
I have to add a bootloader on a board? If yes where i can find it?
Can you help me to found the error?
Thanks again for your time.
Best regards
