NRF5340 HCI RPMsg sample problem

[SteveG128]

Hi,

I'm using the Zephyr sample peripheral_hr mostly as is.

I get the following log messages when I run:

[00:00:17.350,280] <inf> fs_nvs: 2 Sectors of 4096 bytes
[00:00:17.350,555] <inf> fs_nvs: alloc wra: 0, fd0

Advertising failed to start (err -11)
I have repeatedly read all of the Nordic documentation about working with the nrf5340 and I'm pretty sure I'm compiling and flashing the sample properly. I've also repeatedly searched this and other forums as to why advertising fails to start.

I assume that I'm missing some obscure CONFIG_ setting. Can anyone offer me a clue as to why bt_le_adv_start is returning a -11 (no more processes) error in a sample program?

Hi,

The sample should work out of the box on the nRF5340 DK and does so when I test on the DK with nRF Connect SDK 2.2.0. Can you let me know which nRF Connect SDK version you are using, which exact changes you have made to the sample (as you write that the sample is "mostly as is"), and how you are testing?

Einar,

I was using SDK V2.1.0.

But the problem was/is using CONFIG_BT_SETTINGS=y and it's related CONFIGs. For now I commented them out and I will troubleshoot the problem when I really need to save my setting in NV storage.

Please feel free to close the ticket.

Regards

Steve
