LPN won't unprovision

Hi,

Have you stepped through the code and see if the node is actually reset?

What SDK version are you using?

Hi,

But have you debugged the code to see if these functions:

(void) proxy_stop();
mesh_stack_config_clear();
dsm_clear();
node_reset();

are called?

It seems like the functions aren't really called at all.

One thing of note is that I do have the bootloader (/Bootloader/nrf52833_secure_bootloader.hex) running on it as well for DFU.

I don't think this will cause any issue.

Sorry for the delay!

I walked through with a debugger and everything looked right. I added these messages to ensure full execution:

void mesh_unprovision(void)
{
__LOG(LOG_SRC_APP, LOG_LEVEL_INFO, __RECEIVE__ "1\n");
(void) proxy_stop();
__LOG(LOG_SRC_APP, LOG_LEVEL_INFO, __RECEIVE__ "2\n");
mesh_stack_config_clear();
__LOG(LOG_SRC_APP, LOG_LEVEL_INFO, __RECEIVE__ "3\n");
dsm_clear();
__LOG(LOG_SRC_APP, LOG_LEVEL_INFO, __RECEIVE__ "4\n");
node_reset();
__LOG(LOG_SRC_APP, LOG_LEVEL_INFO, __RECEIVE__ "5\n");
}

Hi,

I'm not seeing node_reset() being called since 4 isn't being printed. Can you see if this is the case?

I think it had to as I have init messages pop up again after it should have been called. 

Hi,

It seems pretty strange. Could you try with the LPN example without any modifications? Pressing button 4 should reset the node. Do you see the same behaviour?

I found adding:

    mesh_stack_power_down();

At the end of the function calls did the trick.
