RE: Developing Bluetooth Low Energy products using nRF Connect SDK

Marte Myrvold — Tue, 17 Oct 2023 07:17:52 GMT

Hi Chang,

The nRF9160 SiP does not support Bluetooth, while the nRF52840 SoC does. Therefore, when you build a sample using Bluetooth for the nRF9160 (nrf9160dk_nrf9160) you need to configure the nRF9160 on the nRF9160 DK to work as a Zephyr host and the nRF52840 on the DK as a Zephyr Bluetooth controller. This is done by adding zephyr,bt-uart. Make sure to also add the following in prj.conf:

CONFIG_BT_HCI=y
CONFIG_BT_CTLR=n
CONFIG_BT_H4=y

For this to work, you also need to program the nRF52840 on the DK (nrf9160dk_nrf52840 build target) with the Connectivity bridge firmware.

Best regards,
Marte

Hi,

Thank you for your reply! I will try it later. BTW I find I can build my code with nrf9160-nrf52480 mode.

Do you know what reason makes that happen?

Sincerely,

Chang

Hi,

It is complaining about the device bt,uart:

E:\482w\ncs\v2.5.0-rc1\zephyr\include\zephyr\device.h:85:41: error: '__device_dts_ord_DT_CHOSEN_zephyr_bt_uart_ORD' undeclared here (not in a function)
85 | #define DEVICE_NAME_GET(dev_id) _CONCAT(__device_, dev_id)

You need to add this device to your devicetree overlay:

/ {
	chosen {
		zephyr,bt-uart=&uart2;
	};
};

Make sure to delete the build directory completely before rebuilding when making devicetree changes.

Best regards,
Marte

Hi,

I use nRF9160-DK for this and I find I can't insert code since there is no response when I click the ok button in insert-code.

Here are my overlay file, hope you can find some mistake here. These errors really make me frustrated. Thanks for your help again!

Sincerely,

Chang

Hi,

Which board are you building for?

Please upload the complete build log using Insert > Code.

[quote user=""] I try to add an overlay file and change SDK and the result is same.[/quote]

Can you share the overlay file you added?

Best regards,
Marte
