Yes, to my understanding we are going to have a fix in a future version of the LTE LC library.

Thank you very much for reporting that.

Best regards,

[quote userid="114944" url="~/f/nordic-q-a/124794/at-rai-2-and-at-cfun-0-at-cfun-1-cycle/553758"]in general the notification subscriptions are not stored, but for the ones enabled by the LTE LC library, the configuration should be stored on the application side. [/quote]

Then it's a bug, isn't it?

Okay, so in general the notification subscriptions are not stored, but for the ones enabled by the LTE LC library, the configuration should be stored on the application side. For %RAI it is currently not.

[quote user="AchimKraus"]What may help in such cases would be to add a "custom hook/callback" for cfun.c/enable_notifications. It could be done in the NRF_MODEM_LIB_ON_CFUN/ cfun=0 callback, but in "enable_notifications" the usage may be more straight. [/quote]

Yes, you are right, a solution for that is to enable all the notifications needed in that callback.

Best regards,

Thanks!

There is no hurry from my side.

I found some time ago a similar issue with the SMS notification and so I started to consider, that if the modem at-cmd docu is explicit about sustainability over an power off/on cylcle, then it may be clearer.

Adding two new codes LTE_LC_FUNC_MODE_BEFORE_NORMAL and LTE_LC_FUNC_MODE_BEFORE_ACTIVATE_LTE may be an idea for a future support of custom "enable_notifications".

Hello,

I am looking into it, I hope I will have something during the next week.
