Failed to create advertising set (err -5) with Peripheral_Power_Profiling example

[MaximeCharriere]

Hello,

I have a nRF5340-DK card that I want to test with the "Peripheral_Power_Profiling" example. I use the SDK v2.2.0 and VS Code for this. I didn't make any modification to the code, but I get the following error (print of the serial port :

*** Booting Zephyr OS build v3.2.99-ncs1 ***
Starting Bluetooth Power Profiling example
Reset from pin-reset
I: 2 Sectors of 4096 bytes
I: alloc wra: 0, fe8

W: opcode 0x2036 status 0x01
Failed to create advertising set (err -5)

I don't understand, the example worked at first, but after trying to modify the file "...\peripheral_power_profiling\child_image\hci_rpmsg.conf" I got this error that appeared. I tried to put the file back as original, and I also tried to uninstall completely the toolchain and nRF connect for desktop but without success. I still have the issue.

Do you have an idea of the problem?

Thank you and best regards,

Maxime

Hi Maxime,

What was the change you made to hci_rpmsg.conf?

Have you tried to erase the SoC completely before reflashing?

Best regards,

Hieu

In fact, I had inadvertently deleted the file. And I put it back (and then also redid everything from the beginning..) but the problem remains. I also did an "Erase All", but without success

After following this post: 

get error message when running exsample project on nrf5340DK - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com) , 

I managed to solve my problem by adding : 

CONFIG_BT_EXT_ADV=y

CONFIG_BT_PER_ADV=y

to:

samples/bluetooth/hci_rpmsg/prj.conf

But I really don't understand why it solved my problem, and why it worked before without it and not now?

When you flash the device, did you make sure that you are flashing both the application core and the network core?

Dear Hieu,

It seems that our answers have crossed :) . Do you have an explanation for my last response ?
