Measuring round-trip message delivery time of Thred COAP

[Gregory1992]

I am in process of doing my eng. thesis and apart from setting up Thread network part of my work is to measure delivery time of messages.

For now I have an application based on simple COAP server and another based on simple COAP client, and they are capable of sending messages from client to server that responds with corresponding actions acting as end-node. 

I'm wondering if you have any tips how could I achieve two-way communication needed to do time measures of round-trip data delivery (using local clock on given device).

Thanks

Hi,

 

You could use the 802.15.4 sniffer for this purpose:

https://github.com/NordicPlayground/nRF-802.15.4-sniffer

I suspect this will come in handy for debugging further in your project, not just for time measurements.

Do note that this sniffer is experimental, and does not work properly on windows. However; it shall work on linux and MacOS.

*edit* Windows support was added last week: https://github.com/NordicPlayground/nRF-802.15.4-sniffer/commit/d7804368fc263446ff8005b2a425bc137f7dde14

Kind regards,

Håkon
