nRF54L15 Mesh Light Ctrl: How to Keep Power On Up Setting After Mesh Reset?

[ShawnL]

Hi there,

I'm working with the nRF54L15 and using the light_ctrl sample from the Bluetooth Mesh SDK NCS3.1.0 .

I have a set of mesh light nodes, and I configured power_on_up to BT_MESH_ON_POWER_UP_ON to ensure the lights turn on after a power cycle.

However, when I perform a Mesh Reset (via nRF Mesh App), the power_on_up setting reverts back to BT_MESH_ON_POWER_UP_OFF. This requires me to reconfigure it manually after each reset.

My question:
How can I modify the code or configuration so that after a mesh reset, the power_on_up value remains BT_MESH_ON_POWER_UP_ON without requiring additional configuration?

I understand that mesh reset clears node configurations, so is it possible to set power_on_up  to BT_MESH_ON_POWER_UP_ON when perform the Mesh Reset?

Any guidance or suggestions would be greatly appreciated.

Thanks in advance!

Best regards,

Shawn

Update

In functionality: bt_mesh_ponoff_srv_reset" 

I modified 

srv->on_power_up = BT_MESH_ON_POWER_UP_OFF;

to

srv->on_power_up = BT_MESH_ON_POWER_UP_ON;

 

After executing mesh reset, the power on off server is reset to "default", but in next power up, the lightness is still off, when I read the power on off server on power up status, it`s default, strange.

Do I need to set other parameters?
