https://devzone.nordicsemi.com/f/nordic-q-a/17073/nrfl01p-ack-on-some-pipeMy net is a star type with many nrfL01P+ units. Now i simply use only pipe 0 with no acknowledge (and same frequency for all units). My question is if can I use pipe 1 (for example) to privately comunicate, from one unit, with the centre of the networken-USTelligent Community 13Tue, 18 Oct 2016 09:22:58 GMThttps://devzone.nordicsemi.com/thread/65481?ContentTypeID=1Tue, 18 Oct 2016 09:22:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3836759b-f7e5-43ce-a82c-053310b6dbd1ovrebekk<p>Hi Enzo. Did you figure this out in the end?<br /> I think I handled a similar case from you recently.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/65482?ContentTypeID=1Sat, 15 Oct 2016 21:05:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:794afb61-0aa6-422a-bc33-c26217e6db08enzo<p>Thanks Torbjorn, i tried in the past in this way with no success; i&#39;ll test more carefully.
