When the mesh protocol emits a package it will send the package on all 3 channels and on the listening site the radio continuously switchesen-USTelligent Community 13Thu, 23 May 2019 12:15:30 GMThttps://devzone.nordicsemi.com/thread/188819?ContentTypeID=1Thu, 23 May 2019 12:15:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a0f49fc6-3fd0-4a0e-9a1e-6fbb0fbabc9bhaakonsh<p>I&#39;m afraid that it is dependent on the individual configuration of the mesh network with regards to re-transmissions, the number of L2Cap channels, as well as the on-air time of each individual L2Cap channel, and the frequency of activity of each L2Cap channel.&nbsp;The on-air time of an L2Cap channel is again dependent on payload length and clock accuracy.&nbsp;<br /><br />You&nbsp;will have to find the optimal configurations by calculation or trial-and-error.&nbsp;</p><div style="clear:both;"></div>
