Pings between nodes in mesh nRF52840

[Rorisang]

Hi. I have been going through the mesh examples. Now i need to know how to send pings between any two nodes in the mesh. My aim is to first be able to successfully ping a target and have it send a ping back to whichever node pinged initially. How can i do this? Subsequently, i would like to know how long the ping/ping-back interaction takes. Any simple way to conduct this experiment? Thank you.

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.

Ok. thanks for that. I will try the heartbeat messages and see how far I get.
