Need a replacement for mpsl_radio_notification_cfg_set, which is no longer available

[Jon]

Hi,

We have a product in production which uses the mpsl_radio_notification_cfg_set() function along with a callback to control an external GPIO when thre is radio activity. We do this to enable an external switcher supply while the radio is in operation, since we also make use of a high-power PA and selectively enable the switching supply only when the radio is operating.

We need an alternative to this functionality. Can you please help us to understand what alternative is available?

Thanks,

Jon

Hi Jon,

Looks like it has been dropped, though there are alternatives, like what was also mentioned the case I linked to as well as for instance this one.

Would any of these alternatives work for you? What NCS version are you using?

The Bluetooth Event method will not work, since we are using Thread and Bluetooth and need these events for Thread. The Radio START and STOP events might work, but with MPSL notifications we were using a MPSL_RADIO_NOTIFICATION_DISTANCE_200US so that we received the event early enough to turn on our power supply before radio operation actually started.

I see. And what about the NCS version you are currently using?
