nRF5340 bt_le_ext_adv_create fails with err -5 in various samples

Question

Nrf Connect Version v2.1.2

VSCode Plugin v2022.10.30

Using various samples on my nRF5340DK fail with the following error codes:

hap_ha sample:

I added the folders to the workspace and created a build config. Using all default values results in the above mentioned errors.

What am I doing wrong?

Thanks in advance.

Hi, The example only work with the LE Audio Controller Subsystem for nRF53 (see nRF5340 Audio ), so you need to do a few things. Firstly, add the configs as this post indicated. Then program the firmware hex found under nrf\applications rf5340_audio\bin\ on the network core, and the application core firmware you just built. You should be able to see the log like this ------------------ hap_ha: ------------------ *** Booting Zephyr OS build v3.1.99-ncs1-1 *** Bluetooth initialized Advertising successfully started [00:00:00.267,211] bt_pacs: No callback for publish_location [00:00:00.274,597] bt_hci_core: Controller to host flow control not supported [00:00:00.281,585] bt_hci_core: Identity: CA:3E:A2:9E:02:E3 (random) [00:00:00.281,585] bt_hci_core: HCI: version 5.2 (0x0b) revision 0x0ce7, manufacturer 0x07e8 [00:00:00.281,616] bt_hci_core: LMP: version 5.2 (0x0b) subver 0x0ce7 ------------------ unicast_audio_server: ------------------ *** Booting Zephyr OS build v3.1.99-ncs1-1 *** Bluetooth initialized Location successfully set Advertising successfully started [00:00:00.274,627] bt_hci_core: Controller to host flow control not supported [00:00:00.280,059] bt_hci_core: Identity: DC:A6:0A:90:AC:EE (random) [00:00:00.280,090] bt_hci_core: HCI: version 5.2 (0x0b) revision 0x0ce7, manufacturer 0x07e8 [00:00:00.280,090] bt_hci_core: LMP: version 5.2 (0x0b) subver 0x0ce7 Regards, Amamda H.
