Alternative of radio notifications API in NCS 2.7.0 with nrf5340 cpuapp

[Ben_Squar3d]

Hi,

Like some other users, I face an issue migrating from ncs<2.6.0 to ncs 2.7.0 regarding radio notification. 

I saw it is possible to use the PPI for the EGU IRQ to be triggered on RADIO event, as shown in these posts

Alternative of mpsl radio notification API in NCS v2.6.0 - Nordic Q&A - Nordic DevZone - Nordic DevZone

MPSL radio notification API: why dropped? - Nordic Q&A - Nordic DevZone - Nordic DevZone

Unfortunately, NRF_RADIO register is not accessible from the cpuapp on nrf5340. 

What is the alternative to be able to catch NRF_RADIO_EVENT_END event or equivalent with ncs2.7.0 and nrf5340? 

Thank you for your help.

Hi,

Thank you for your answer. It seems a bit too complicated indeed. 

We managed to use additionnal timers instead of looking for the missing event.

Finally, I first read your opening post as you were using Radio Notification is 2.6.1, but it was removed in 2.7.0. I have seen now that isn't the case. Do you need Radio Notification or something like that for a new issue? If so, there might be other approaches as well.

I don't get it sorry. We were working with nrf52 + ncs<2.70 at first and when migrating to ncs 2.7.0, we were using additionnal timers to workaround the missing event. This introduces new issues and the right fix would have been to retrive the event again. While it is possible to to so with nrf52, it is not easily possible with nrf53 it seems, so we'll stick to the workaround we have. Thank you for your answers

Best regards

Oh, I meant I misunderstood the origin of the issue when I read your opening post. It's nothing important now.

Right. This approach does seem like too much for debugging, if you have a different workaround.

I will close this ticket then. If you have further questions on the topic, please feel free to reopen it any time.
