RE: Bluetooth Mesh Provisioner Reset

It turned out I just needed to wait a little bit longer before rebooting. Apparently, the Settings takes a bit of time to save/delete. A 2 second delay was not long enough.

For nodes:

bt_mesh_reset();

k_msleep(4000);

sys_reboot(SYS_REBOOT_COLD);

As for the provisioner, it is the same but with bt_mesh_cdb_clear();

On provisioner, you must not reuse a unicast address while another device still has valid credentials for it. It looks like there are clearly many things persistently stored, best is make sure to delete the subtree and CDB and recreate the cdb before provisioning again.

bt_mesh_cdb_clear();

settings_delete("bt/mesh");
bt_mesh_settings_store_pending(); /* force immediate write if enabled */
k_msleep(3000); 

sys_reboot(SYS_REBOOT_COLD);
