Link quality information , like CRC failure and packet losses on a link

[daviddedwin]

nRF52832
SDK 17.2

We are trying to get the packet loss/error information on a per channel basis. It is similar to what is being discussed in https://devzone.nordicsemi.com/f/nordic-q-a/11452/connection-stability-packet-loss-etc . This is to understand packet loss on a connected mesh and also to react gracefully to packet losses.

This is also present in the nRF Mesh SDK as the scanner_stats_get function .

Can you point me at the API that can give us this information.
I have already see the RSSI function and the qos channel survey function, these do not provide the information that is needed on the exact packet losses.

Thanks

Hi.

Like you said, in the nRF5 SDK for Mesh you have the scanner_stats_get () function that can give ytou some statistical information.

Do you need help using the function? Not sure if I understand what you are having trouble with.

Can you point me at the API that can give us this information.

You already mentioned the function that can provide you with the information. 

Br,
Joakim

This is a connected mesh so there are GAP connections established between the Centrals and Peripherals running on the nodes. The link quality i.e. CRC and errors  are needed for the connections. Please provide the API for this. Hope this is clearer.

Ah I see. I thought you were using our nRF5 Mesh SDK.

Then I don't think we have any API that will work out of the box in order to access link quality data. Not other than the RSSI and qos that you already mentioned.

Are there other ways to extract the CRC failures and long packet errors ? Pointers are welcome.
