https://devzone.nordicsemi.com/f/nordic-q-a/62179/how-to-increase-the-number-of-low-power-nodes-per-friend-nodeHello, I&#39;m setting up a mesh network with low consumption sensors and I&#39;m using the Low power node example. I&#39;m having trouble increasing the number of devices supported by a friendly node. according to what was reported here on the nordic forum , theen-USTelligent Community 13Tue, 09 Jun 2020 09:15:41 GMThttps://devzone.nordicsemi.com/thread/253974?ContentTypeID=1Tue, 09 Jun 2020 09:15:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a31b84c4-9f75-4e94-8895-7644b2843125tesc<p>Hi,</p> <p>The maximum number of friendships is limited by amount of RAM, and by the size of the core_tx_bearer_bitmap_t data structure (currently uint32_t). Changing the data structure may void qualification, meaning you may have to qualify the mesh stack from scratch instead of reusing our already obtained QDID.</p> <p>Ending friendships in order to get &quot;vacant spots&quot; for new friendships should work, if potentially losing messages for the old friendship LPN is OK.</p> <p>For more information and full-length answers, please see the thread <a href="https://devzone.nordicsemi.com/f/nordic-q-a/56982/what-are-the-limits-on-the-number-of-friendships-a-friend-node-can-support">What are the limits on the number of friendships a friend node can support?</a> where similar questions were asked (and answered) as part of the conversation.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
