Time required to send 1 thread message from SED

[Rajendra]

Hello there,

I am developing a coap based client-server application which has thread mesh network. Client is a sleepy node here.

Dev kit: nrf52840

Thread SDK: nRF5_SDK_for_Thread_v0.10.0_e1c3d11

What is the typical timing required to broadcast 1 thread message considering following?

- Wake up the device
- Initialization
- Send 1 thread message with 16 bytes payload
- Disable the thread (deinit)
- Deep Sleep (NRF_POWER->SYSTEMOFF = 1;)

Hello,

This time will be highly non-deterministic. Simple attachment to Thread network can take from 0,2s to 5s and is affected by air traffic, random jitters, or other non-deterministic factors defined in the Thread protocol. This 16 byte payload is transfered using CoAP? If yes then it will depend on message type - confirmable or non-confirmable. You can find some of those times in table on this page: http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.threadsdk.v0.11.0%2Fthread_multiprotocol.html Also why don't you use shalow sleep?
