Hi,

Bluetooth Mesh does not have the concept of pinging. Rather, it uses "Heartbeat messages" to diagnose the network, which we do support in nRF5 SDK for Mesh. It is not a "normal" mesh model in that it is really part of the transport layer, and in our SDK it is configured through the config_client_heartbeat_*() functions. For more information about it I refer to the Bluetooth Mesh Networking Specifications.

If you need the time of ping/ping-back interaction, however, then I am afraid it looks like you must implement your own model and time the round trip time yourself. For instance using the app timer library from the nRF5 SDK.

Regards,
