ok thanks

run

\ncs1.7.1\toolchain\git-cmd.cmd

enter

\ncs1.7.1\zephyr\samples\bluetooth\periodic_adv\build_nrf52840dk_nrf52840\

west flash

west build -b nrf52840dk_nrf52840

using west builded once,then it will be can build and debug by SES IDE.

good luck.

Thanks so much Elfving,

I just verified your solution, it does the trick. Now I can continue my development.

Best wishes,

Libo

Hello Libo!

Ah, yes it seems that you would need these two configurations as well:

CONFIG_BT_CTLR_ADV_EXT=y

CONFIG_BT_CTLR_ADV_PERIODIC=y

It should work now, I just tried it myself. If you want to try the periodic sync example you would need CONFIG_BT_CTLR_SYNC_PERIODIC.

Best regards,

Elfving

Thanks very much Elfving, Using the same workspace I did yesterday, I applied this config in the prj.conf file. Now the output has a different error code ( -5), see the screenshot below. I believe it still doesn't work. Could you provide a validated example as part of nrf Connect, as you stated the periodic advertising is supported by nrf52833 and nrf52840.

Thanks a lot,

And the prj.conf file is:

CONFIG_BT=y
CONFIG_BT_EXT_ADV=y
CONFIG_BT_PER_ADV=y
CONFIG_BT_DEBUG_LOG=y
CONFIG_BT_DEVICE_NAME="Test Periodic Advertising"
CONFIG_BT_LL_SW_SPLIT=y

Hey again Libo!

I am sorry, I see now that you are right in that there is an issue using that sample without some configuration. It is a zephyr example, and the Nordic softdevice controller does not currently support periodic advertising. This means that you would have to switch to using the Zephyr controller for the example to work.

You can do this by adding CONFIG_BT_LL_SW_SPLIT=y to your configuration file.

Best regards,

Elfving

Thank Elfving, maybe I should have posted some screenshoting that could help you debug the issue.

To keep steps simple, let focus on the nRF9160DK (PCA10090 V1.0.0, 2021.11) board for this issue, I just created the workspace using the Segger Embedded Studio which comes with nRF Connect SDK 1.7.0 for macOS ( I'm using macOS Big Sur v11.6, I remember I got same result from my Ubuntu as well).

0. Launch the Segger Embedded Studio from nRF Connect v3.7.1 Toolchain Manager, choosing nRF Connect SDK V1.7.0 Open IDE.

1. Import project with the following configuration, I did a clean build, all good.

2. Without any code change, build the project and run on the nRF9160dk, on the nRF52840 MCU, by clicking Debug-> Go. I can see from the terminal shown as below. You can see the second line print "Fail to set periodic advertising ..."

3. I reset the session and set a breakpoint to capture "

err = bt_le_per_adv_set_param(adv, BT_LE_PER_ADV_DEFAULT);"

shown as below:

Hope this can help you replicate the issue. Let me know what I missed in bringup the function.

Thanks a lot.

Libo

Hey Libo, sorry about the delay!

[quote user=""]Could you advice what is the root cause? Is it on the chip or some code configuration? [/quote][quote user="liulibo"]I think this is the same error I got when I pick nrf9160_nrf52840 and test on my nrf9160dk board[/quote]

That is weird, the periodic_adv example should work on the BBC Microbit, as well as on the nrf9160_nrf52840. It does for me.

[quote user="liulibo"]I know that the nrf52840 is not supported for this example though. [/quote]

What is giving you that impression?

I assume you have built and flashed other samples to these boards successfully? Could you try checking the "Clean Build Directory" checkbox before opening the project?

Best regards,

Elfving

Thanks so much. I think this is the same error I got when I pick nrf9160_nrf52840 and test on my nrf9160dk board - I know that the nrf52840 is not supported for this example though.

Hello Libu!

I am looking into it, but I will have to get back to you.
