how to add ble central on mqtt sample code in the nRF Connect SDK.

stevenlin

hi all ,

now , i need add create mqtt ble gateway .

it compiler failed follow message :

C:/temp/ncs/zephyr/drivers/serial/uart_nrfx_uarte.c:1272:9: error: 'DT_NORDIC_NRF_UARTE_UART_2_LABEL' undeclared here (not in a function); did you mean 'DT_NORDIC_NRF_UARTE_UART_1_LABEL'?
2> C:/temp/ncs/zephyr/include/device.h:107:11: note: in definition of macro 'DEVICE_AND_API_INIT'
2> C:/temp/ncs/zephyr/drivers/serial/uart_nrfx_uarte.c:1271:2: note: in expansion of macro 'DEVICE_DEFINE'
2> C:/temp/ncs/zephyr/drivers/serial/uart_nrfx_uarte.c:1346:2: note: in expansion of macro 'UART_NRF_UARTE_DEVICE'
Build failed

how to do it ?

in my setup

1. copy ble.c/ble.h files

from ~ncs\nrf\samples\nrf9160\lte_ble_gateway\src to ~ncs\nrf\samples\nrf9160\mqtt_simple\src

2.CMakeLists.txt

target_sources(app PRIVATE src/ble.c)

3. add or change prj.conf ,
# Enable the UART driver
CONFIG_UART_INTERRUPT_DRIVEN=y
CONFIG_SERIAL=y
CONFIG_CONSOLE=y
CONFIG_CONSOLE_HAS_DRIVER=y
CONFIG_UART_CONSOLE=y

# Enable Bluetooth stack and libraries
CONFIG_BT=y
CONFIG_BT_H4=y
CONFIG_BT_WAIT_NOP=y
CONFIG_BT_CENTRAL=y
CONFIG_BT_GATT_CLIENT=y
CONFIG_BT_GATT_DM=y
CONFIG_BT_SCAN=y
CONFIG_BT_SCAN_FILTER_ENABLE=y
CONFIG_BT_SCAN_UUID_CNT=1

CONFIG_UART_2_NRF_UARTE=y
CONFIG_UART_2_NRF_FLOW_CONTROL=y
CONFIG_UART_INTERRUPT_DRIVEN=y

# AT Host
#CONFIG_UART_INTERRUPT_DRIVEN=n
CONFIG_AT_HOST_LIBRARY=y

# Disable Modem traces, since we need UART1 for HCI
CONFIG_BSD_LIBRARY_TRACE_ENABLED=n

follow this linker about CONFIG_UART_2_NRF_UARTE , it need "Kconfig"  to enable menus

    Hi.

    In addition to the configuration options in prj.conf you also need to include the nrf9160_pca10090ns.overlay and child_secure_partition_manager.conf files from the lte_ble_gateway sample in your project.

    The overlay file describes the hardware, and tells the UART driver how to configure the UART2 peripheral, while the configuration file tells the secure partition manager to configure the UART2 peripheral to be used from your non-secure application.
