I don't think we have a set date or version where this label is removed.

But I'll ask if we have a timeline.

The "experimental" label makes me a little nervous to use in a shipping product. When will this label be removed?

Thanks

Hi again.

I'm afraid that we don't have any guidelines on this, apart from what is available in the documentation here:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.1/kconfig/CONFIG_BT_MESH_ADV_STACK_SIZE.html#std-kconfig-CONFIG_BT_MESH_ADV_STACK_SIZE

But if you have any specific questions, I can forward these to our development team.

Br,
Joakim

Thanks for the update.

I don't think we have any documentation on this. But I can request any guidelines from our developers, and get back to you.

Br,
Joakim

Update 4

The firmware for the second board was built on a different machine and the compiler version there was not the one recommended by nordic

So this part is resolved as well

The only question remains
Is there a doc with recommendations on sizes of various buffers i.e CONFIG_BT_MESH_ADV_STACK_SIZE ,etc for nRF52480 MCU?

Update 3

On one board I was able to fix this by adding the following config items

CONFIG_BT_RX_STACK_SIZE=4096|

CONFIG_MAIN_STACK_SIZE=1024

CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=4096

But on another board ( same MCU, different board revision) the crash still occurs

Is there a doc with memory configuration requirements for mesh under Zephyr, for various MCUs ?

Update

On another board there is a different crash during provision when “Requesting default TTL”
This is when using the iOS version of the nrf mesh app
