Running BLE HR Peripheral demo on nrf9160-DK

Question

Hi,

I have nrf9160-DK and I am using NCS v1.6.1. I am trying to run HR Peripheral sample application on the nRF9160DK board.

I have flashed nrf52840 with hci_lpuart sample example (The same as mentioned in README of lte_ble_gw sample application) and updated HR peripheral project configuration as below,

CONFIG_BT=y
CONFIG_BT_H4=y
CONFIG_BT_WAIT_NOP=y
CONFIG_BT_DEBUG_LOG=y
CONFIG_BT_SMP=y
CONFIG_BT_PERIPHERAL=y
CONFIG_BT_DIS=y
CONFIG_BT_DIS_PNP=n
CONFIG_BT_BAS=y
CONFIG_BT_HRS=y
CONFIG_BT_DEVICE_NAME="Zephyr Heartrate Sensor"
CONFIG_BT_DEVICE_APPEARANCE=833
CONFIG_HEAP_MEM_POOL_SIZE=16334
CONFIG_MAIN_STACK_SIZE=8192
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=1024
CONFIG_UART_INTERRUPT_DRIVEN=y
CONFIG_NRF_SW_LPUART=y
CONFIG_NRF_SW_LPUART_INT_DRIVEN=y 
CONFIG_UART_2_ASYNC=y
CONFIG_UART_2_INTERRUPT_DRIVEN=n
CONFIG_UART_2_NRF_HW_ASYNC=y
CONFIG_UART_2_NRF_HW_ASYNC_TIMER=2

While flashing HR peripheral on nrf9160, I am getting error

Help to how to resolve this error.
