One PTX, many PRXhttps://devzone.nordicsemi.com/f/nordic-q-a/16486/one-ptx-many-prxI&#39;m using a module that has nRF24L01 mounted. When I transmit to many PRXs, using the same frequency and channel, I expect to receive many ACK signal at the same time. Does this give rise to problems? Must I transmit with ACK disabled?

When there are several ACKs sending at the same time you have the risk of radio interference and get no ACK.</p><div style="clear:both;"></div>RE: One PTX, many PRXhttps://devzone.nordicsemi.com/thread/63112?ContentTypeID=1Sat, 17 Sep 2016 18:28:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3ef356f4-6f1b-4c8f-8051-fd0af7727de8enzo<p>I&#39;ve read in developer zone that you can not use ACK when more than 1 PRX is active. So I will try to disable ACK when talking to other PRX units. My network is a star network, in wich the center is sometime PTX (and the others PRX), or the opposite. In this last case PTXs transmit sequentially.</p><div style="clear:both;"></div>
