https://devzone.nordicsemi.com/f/nordic-q-a/13226/how-many-nodes-can-ant-support-when-auto-shared-channel-is-usedWe have an use case that we may need to support up to ,say 500 sensor nodes and it may be added or removed dynamically. And we should collect all sensor data within 3 seconds. I just wonder if ANT can support so many nodes with the limit of response timeen-USTelligent Community 13Thu, 21 Apr 2016 07:13:28 GMThttps://devzone.nordicsemi.com/thread/50428?ContentTypeID=1Thu, 21 Apr 2016 07:13:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a75a1925-6364-4507-b60f-3eb2ff002cebKenneth<p>I think the best would be to refer you to the documentation in the nRF5 SDK: <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/esb_users_guide.html?cp=4_0_0_5_2">Enhanced ShockBurst User Guide</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/50427?ContentTypeID=1Thu, 21 Apr 2016 06:57:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c308f3a4-8022-4a51-9ed1-581af535ecf7Alex Cheng<p>Thanks for your feedback. Could you please detail the advantage of using ESB lib ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/50426?ContentTypeID=1Mon, 18 Apr 2016 12:26:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:15215e59-2abc-4207-a937-753762e37d21Kenneth<p>I doubt you will be able to ensure both the high amount of nodes and response time with only one receiver. In theory your suggestion will work, but once you have some packet loss, e.g. due to interference, then you are lost. I think you need more than one receiver for this to work reliable. You might get better resolution building your application using our ESB library instead of ANT, but then you will need to spend more time developing, as that ESB library only provide the low level radio functionality (rx and tx with retransmission), and no timing, pairing or co-existence handling.</p><div style="clear:both;"></div>
