measure total time required to send message from client to sever and server acknowledges that message to client using BLE MESH stack (2.0.1)

[Nikunj Patel]

Hi...,

i have measured round trip delay from client to server.

Now I want to measure total time required to send  message from server to client and client acknowledges that message to server using BLE MESH stack (2.0.1) light-switch example demo.

is it possible or Not..?

Thanks,

This should be possible. You can use the log_timestamp_get() function located in log.h to get a timestamp & then have logging enabled via RTT for example to see when the message gets sent from the server & when the server gets the ACK from the client. Then, you just compare the difference between both timestamps to figure out the total time.

in onoff light switch demo example, server only send light status to client. in that case, as i assume, client will not acknowledge to that message.so using that, i can not able to measure round trip delay.

is there Any different way to measure roundtrip delay?
