calculating Round Trip Time (latency) for Bluetooth mesh network

Hello, I'm using the bluetooth helper functions

1) https://www.mathworks.com/help/comm/examples/bluetooth-mesh-flooding-in-wireless-sensor-networks.html?searchHighlight=data%20averaging&s_tid=doc_srchtitle

2) https://www.mathworks.com/help/comm/examples/Energy-Profiling-of-Bluetooth-Mesh-Nodes-in-Wireless-Sensor-Networks.html

to simulate the Working of Bluetooth mesh network.i wanted to calculate the Round trip time between nodes. Can anyone help me with this?

Hi Durgaprasad,

As of now, the example does not provide the "round-trip time" as a metric, but you can calculate a similar metric using these examples, the "average end-to-end latency" of application packets from the source to the destination nodes. Take a look at it to see if this is helpful.

For example, by setting the sourceDestinationPairs to [4 5] in BLEMeshEnergyProfilingExample, you'll be able to get the value of "end-to-end application packet latency" at node 5, for packets originating from node 4. This value can be accessed at node 5 as node5stats.App.AveragePacketLatency, where node5stats is statistics(meshNodes(5)).

Best,
