How to re-provision a node to same address with nRF52840 DK board in mesh

[Sash]

i'm using nRF mesh sdk v2.1.1 with 2 boards and 1 provisioner board. I have un-provisioned 1 board with the help of config_client_node_reset().  I want to know the procedure to re-provision the unprovisioned node with same address.Please give me solution.

When you remove the node (calling config_client_node_reset() ) you can delete the device key in the dsm list on the provisioner by calling dsm_devkey_delete()

[Sash]

ok, what you saying is, i have to call sdm_devkey_delete() after config_client_code_reset() in provisioner main.c but the dsm_devkey)delete() contains handle parameter. dsm_clear() will not delete this devkey?

I'm not sure why you mention dsm_clear() here ?

dsm_clear() is to be called on the provisionee (the node to be removed) not the provisioner.

ok i understand about dsm_clear() now, should i call dsm_devkey_delete() next to config_client_node_rest() in provisioner main.c

Yes, correct.
