Calculating signal strength for the Sleepy End device

[nikhil30081995]

Hello,

I have a sleepy end device publishing data at interval of 100 ms to cloud via Border router. Now i would like to send signal strength information between sleepy end device and its parent device that can be device connected to Border router such as NCP/RCP device OR a FTD device in network.

So is there any API available to calculate the Signal strength info between transmiting sleepy device and its parent ?

I came across this api call : otPlatRadioGetRssi(thread_ot_instance_get()) but it always return 127 value which is invalid. So can any help how can i calculate strength of signal or quality of signal between sleepy end device and its parent.

Thanks in advance.

The neighbor table CLI command and otThreadGetNextNeighborInfo() API provides RSSI information for each neighbor.

Okay so if I have five SED and one FTD in network, running neighbour table command will give Signal Strength/link quality between that device and FTD device.

The neighbor table CLI command and otThreadGetNextNeighborInfo() API provides RSSI information for each neighbor.

Can I use otThreadGetParentLastRssi to get the signal strength between SED and its parent ?

Yes, that can work as well.
