I&#39;ll have to control 400 MODULE Transceive. Which model should I use. thank you.en-USTelligent Community 13Wed, 20 Nov 2013 14:35:55 GMThttps://devzone.nordicsemi.com/thread/4444?ContentTypeID=1Wed, 20 Nov 2013 14:35:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:707d5578-ff96-4b29-b8dc-259619536ed2Ole Morten<p>What you want isn&#39;t something we have any direct examples of, and it is not trivial to get working correctly.</p> <p>With an nRF24L01+ or nRF51822 in 250 kbps mode, you may be able to get 200 m range in open space, but you should not expect a very robust link at this range. You could also consider using the nRF905 transceiver, which will have better range since it uses lower frequencies.</p> <p>Having 400 nodes in your network will also require some clever network design, to make sure that devices doesn&#39;t send at the same time.</p><div style="clear:both;"></div>
