Is it possible to shorten the RRC connection Reconfiguration time?

[chosan]

Dear support team,

I'm using nrf9160 and SLM to create a UDP server and client, and communicating between them. When communicating every 300 ms, there are times when there is a delay of more than one second. After looking into it, it seems that RRC connection reconfiguration takes a lot of time.

Is there any way to shorten this time?

Our environment:

Hardware: nRF9160-DK ,Software modem: mfw_nrf9160_1.3.5.zip application: slm-with-trace.hex (installed from celluar monitor v2.4.1)

Hello,

do you know if RAI (release assistance indication) is enabled in the application?

[chosan]

Nop. Is there any command to know RAI ? (what is RAI...)

[chosan]

AT%RAI? result is %RAI: 0

[Hakon]

Have you tried AT%XRAI?

[chosan]

Yes. response is [ %RAI: 0 ]  as I wote 1 month ago.

[chosan]

Sorry, I missed the character X. The result was [ %XRAI: 0 ].

Should we set some kind of value?

You can set it using this command https://docs.nordicsemi.com/bundle/ref_at_commands/page/REF/at_commands/nw_service/xrai_set.html .

You also need to check if it is supported by the network.

We are using LTE-M. It seems for NB-IoT.

Actually, this command is not work for shorten the RRC connection Reconfiguration time,I had tried.

Did you reproduce this symptom?

we found other solution now. so I close this question. thank you for support.
