Thanks Heidi it is working now

Hi again!

So, I was able to get past the driver error by doing these modifications.

In beacon/boards I added an overlay file "nrf9160dk_nrf9160ns.overlay" that I took from the LTE BLE Gateway sample (nrf/samples/nrf9160/lte_ble_gateway/boards/nrf9160dk_nrf9160ns.overlay)

and I added these configurations to the prj.conf file:

CONFIG_BT_H4=y
CONFIG_BT_HCI=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_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

They are taken from the prj.conf file and boards/nrf9160dk_nrf9160ns.conf file in the LTE Sensor gateway sample. It's possible that not all of them are necessary.

To set up UART2 as non-secure, add the following configuration to a file called "child_secure_partition_manager.conf".

CONFIG_SPM_NRF_UARTE2_NS=y

Then add this to the CMakeLists.txt file, right under cmake_minimum_required.

set(spm_CONF_FILE
  prj.conf
  ${CMAKE_CURRENT_LIST_DIR}/child_secure_partition_manager.conf
  )

Best regards,

Heidi

Hi! That's interesting. I am seeing the same error as you, that the driver isn't registered. I am currently looking into it and asking some of the developers, and I'll update you when I have more information.

Best regards,

Heidi

CONFIG_BT_H4 and CONFIG_SERIAL were already in the active state.

I could not find any configuration about UART hardware flow, but RTS and CTS were defined in either of the boards .dts files. And since I can see reading outputs nRF52840 using LTE Sensor Gateway example which includes hci_lpuart and lte_ble_gateway samples, I assumed RTS and CTS are connected on hardware level.

I added CONFIG_BT_WAIT_NOP but it still gives the same error.

Hi!

You will need to modify the Beacon example to use a separate device as the Bluetooth Controller.

You at least need the configuration CONFIG_BT_H4, which specifies the Bluetooth HCI Driver you're using. This will require the UART hardware flow control lines to be available, so check that as well. CONFIG_SERIAL will need to be enabled as well.

Optionally CONFIG_BT_WAIT_NOP if you want to be notified when the Controller is initialized.

Let me know how it goes.

Best regards,

Heidi
