https://devzone.nordicsemi.com/f/nordic-q-a/75636/rssi-fluctuation-in-mesh-networksHi there, We have a mesh network which runs now for quite some time on our own hardware. We are using heartbeat messages to collect RSSI values between nodes in the network and relay them to a gateway. The heartbeat message is send in intervalls ofen-USTelligent Community 13Tue, 01 Jun 2021 08:44:01 GMThttps://devzone.nordicsemi.com/thread/312785?ContentTypeID=1Tue, 01 Jun 2021 08:44:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1aa9cadf-b8b8-4d6c-9f1e-88110e260ae4michel_93<p>Hi Joakim</p> <p>The network is spread out over a building, so there are nodes that are far away and some near to each other. I analysed the RSSI for one channel and it is quite constant. The fluctuation is therefore only between different channels, which can is possible. So for me thats ok. Thank you</p> <p>Br, Michel</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/312593?ContentTypeID=1Mon, 31 May 2021 09:49:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b7938942-e478-4ec6-9003-7d076dfeb403Joakim Jakobsen<p>Hi.</p> <p>I don&#39;t think that variations of +-10dB can be considered out of normal.</p> <p>RSSI can variate from so many different reasons; noise from other sources, physical obstacles etc.</p> <p>Do you have any more information about the physical design of the network. Are the nodes far away, are they line-of-sight?</p> <p>Br, <br />Joakim</p><div style="clear:both;"></div>
