How to set sending data using control plane (CIoT EPS Optimization using CP) to be able to use %XRAI release assistance

[Michal Mühlpachr]

According https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/nw_service/xrai_set.html control plane data only are supported.

How to set PDN to use control plane instead of user plane (CIoT EPS Optimization using CP) to be able to use %XRAI please ?

Are there any %XRAI usage examples please ?

Hello,

 

Are there any %XRAI usage examples please ?

 There are no samples at the moment, but there is a PR with socket options for RAI.

Hello, tahak you.

How to set PDN to use control plane instead of user plane (CIoT EPS Optimization using CP) to be able to use %XRAI then  please ?

Regads,

I need to check if this is set automatically when using SLM with NB-IoT. I hope to be able to answer you on Monday next week.

 I have confirmed that NB-IoT uses control plane by default when sending.

NB-IoT can use user plane or control plane for data transfer.
If nRF9160 NB-IoT implementation prefers user plane (CIoT EPS Optimization using CP)
how can I distinguish what plane is NB-IoT PDN using to be able to know whether I can use %XRAI ?

Hi! 

Håkon has gone on vacation this week so I have taken over this case. I have asked our LTE experts if there is a way to check if the UE is using control plane for data transfer, and I will let you know when I hear back.

Best regards,

Heidi
