https://devzone.nordicsemi.com/f/nordic-q-a/1479/how-to-synchronize-receiversHello everyone, I want to create a real-time wireless sensor network. There are 8 sensors in the net. I use two nRF24LE1 as receivers to recieve the datas stimultaneously, so I have to use the MultiCeiver function. So how can I synchronize these twoen-USTelligent Community 13Thu, 06 Feb 2014 11:08:53 GMThttps://devzone.nordicsemi.com/thread/6611?ContentTypeID=1Thu, 06 Feb 2014 11:08:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f4c9b8b9-2859-4c91-b2b3-c2b4f6a81662H&#229;kon Alseth<p>Hi Hao,</p> <p>You can synchronize on the ACK that you receive on the PTX. If you have a known payload size, you can calculate the time from when it was sent to when you ACKed it. You will also have to ensure that you adjust for re-transmissions that might have occured (field &quot;ARC_CNT&quot; in OBSERVE_TX register)</p> <p>Note that creating a protocol that does channel hopping and synchronizing is not straight forward. Have you looked into the ANT-products that we have (nRF51422 and nRF24AP2) ?</p> <p>Best regards Håkon</p><div style="clear:both;"></div>
