Clear mesh 3.1.0 data

[bart]

I was wondering what I have to do to clear all stored mesh data on flash.

1. Do I have to initialize the whole mesh, or can I init only a subset?
2. What do I have to do so that the data is not just invalidated, but actually wiped?
3. Is there an event that tells me when it's done?

Using and NRF52832, SDK 15.3.0, SD 132 6.1.1, and Mesh SDK 3.1.0.

Hi. 

You can take a look at the Low Power Node example in the nRF5 SDK for Mesh v.3.2.0 for an example to how this is done. 

In the example; 
Button 4: Reset the device (erases all mesh data).

You can find the source code and the project file of the example in the following folder: <InstallFolder>/examples/experimental_lpn

Best regards,

Thanks, the API documentation of mesh_stack_config_clear() doesn't tell me if the data gets invalidated or wiped though, nor what event to wait for. I prefer not to use mesh_stack_device_reset() to reset the device. I guess I could dive into that function to see what it's waiting for.

Looks like you have to do something like:

mesh_stack_init(...);
nrf_mesh_evt_handler_add(...);
mesh_stack_config_clear();
if (flash_manager_is_stable()) {
	// Done
	return;
}
// Wait for NRF_MESH_EVT_FLASH_STABLE.
