COAP Application Response Time

Description

Hello ,

I am able to fetch temperature, humidity and light data from the motes. However, the response time of the application takes time (say almost 3 to 5 mins between motes), currently I am using three motes and fetching data cylic (continuously).

In real time we need data without any delays, is there any way that I can improve this?

Note -Two Coap app for temperature / humidity and Light
i.e firing two GET commands in my python script

Best Regards,

Sachin Edwin

scenario:

Motes: mote 1 mote 2 and mote 3
Topolgoy: star topology
Dagroot: mote 1 is set as dagroot
App: CoAP app. Mote 2 and mote 3 will sample sensor data when get a GET command from dagroot and send a CoAP to dagroot.

Environment

WIndows, IAR, CC2538(Open Mote)

Hi tengfei,

Thanks for the support.
with https://openwsn.atlassian.net/browse/FW-427#icft=FW-427 & https://openwsn.atlassian.net/browse/FW-423#icft=FW-423 implemented the delay was reduced.
It also depends on the number of Active slots, when no.of motes are increased, active slots must also be increased so that possibility of collision is reduced. Hence data can be achieved much quicker.

@Sachin Edwin, congratulations! Could you tell us what's the final solution for this issue? Did it caused by some bugs in openwsn, https://openwsn.atlassian.net/browse/FW-427#icft=FW-427 , or something else? Thanks a lot!

Hi Thomas ,

Still working on different test setups (outside), I would update on this COAP app delay very soon.

Thanks,
