LPN won't unprovision

I found adding:

mesh_stack_power_down();

At the end of the function calls did the trick.

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

Hi,

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

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,

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.

[quote user="aross11"]One thing of note is that I do have the bootloader (/Bootloader/nrf52833_secure_bootloader.hex) running on it as well for DFU.[/quote]

I don't think this will cause any issue.

I've done a few tests to really be sure:
-I have logging active so I can see my startup message, the startup is displayed, still retains it's friendship status
-We have an external watchdog, I forced an infinite loop so the watch dog would latch, it did, still same issue

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

I'm using Mesh 5.0.0 SDK

Hi,

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

What SDK version are you using?
