power up mesh stack after execution of "mesh_stack_power_down()"

[krajiiva]

Hello

My setup looks like this.
I am using nrf5_SDK_for_Mesh_v5.0.0 with nRF5_SDK_17.0.2.
I have extended the sensor model example (in  nrf5_SDK_for_Mesh_v5.0.0) and call the function "mesh_stack_power_down()" during operation. After calling this function my system also consumes only 5-6uA which is great. However, I can't manage to power up the mesh stack afterwards so there are no mesh asserts. I tried the function "mesh_stack_start()", but that doesn't really work either. Can you tell me how exactly I have to power up the mesh stack after calling the function "mesh_stack_power_down()" and what exactly I have to consider when powering down and powering up the mesh stack.

Thanks already.

Hi,

The stack is not designed to be restarted without rebooting the device after calling "mesh_stack_power_down()".

Hi,

I been talking to one of our developers and it seems that Low Power feature is the correct solution for this case. Then, things like IV Update would be correctly handled by the node. Otherwise, the node may get lost in the network. Poll Timeout can be properly tuned so that the node sleeps most of the time.

But if I use the low power node feature, then my device has to make a friendship with another node, right? This makes the whole network more complicated and my concept is rejected?
Or have I misunderstood something?

Can I use the low power node feature without establishing a friendship with another device? As I said, I just want to achieve the lowest possible power consumption without having to make additional changes like configuring other devices as "friend" for my low power node.
