https://devzone.nordicsemi.com/f/nordic-q-a/36518/concurrent-connections-is-the-limit-really-20I am trying to make a large BLE sensor network, hypothetically anywhere from 20-100 devices in a STAR configuration. I see there is a 20 max limit on concurrent connections. Does that mean I can only have 20 paired devices or can I have X number of devicesen-USTelligent Community 13Thu, 19 Jul 2018 10:22:47 GMThttps://devzone.nordicsemi.com/thread/140646?ContentTypeID=1Thu, 19 Jul 2018 10:22:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:630223ed-4e2e-47a9-9c0a-dc7785d9960bhaakonsh<p>The S140 can handle 20 concurrent connections. The limitation is in the SoftDevice&#39;s scheduler.&nbsp;<br /><br />The maximum number of bonded devices depends on how much memory you&#39;ve got and how much memory is required for each bond depending on the content of the bonding information.&nbsp;<br /><br />The difference between ANT and BLE is not that huge at -2dB.&nbsp;<br /><br />If you can use a mesh network I would rather use BLE mesh or OpenThread.&nbsp;</p><div style="clear:both;"></div>
