nRF52840 Max number of connected deviceshttps://devzone.nordicsemi.com/f/nordic-q-a/38176/nrf52840-max-number-of-connected-devicesHi, We need to design a network with one master and 36 devices connected, with &quot;long range&quot; capability, exchanging sometime messages from 100 to 4000 bytes. The number of communications/minute is not big, but when it&#39;s necessary to cummunicate, iten-USTelligent Community 13Wed, 05 Sep 2018 08:29:20 GMTRE: nRF52840 Max number of connected deviceshttps://devzone.nordicsemi.com/thread/147308?ContentTypeID=1Wed, 05 Sep 2018 08:29:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b56b1863-279b-4275-908b-2513b1b78863bjorn-spockeli<p>Hi Mike,<br /><br />Yes, the S140 v6.1.0 SoftDevice(i.e. BLE protocol stack) supports up-to 20 concurrent connections&nbsp;and this is a hard limit for our protocol stack.</p> <p>If you need 30 concurrent connections then I suggest that you take a look at <a href="https://mynewt.apache.org/pages/ble/">Mynewt&#39;s Nimble</a> stack. It supports up-to 32 concurrent connections and it supports the nRF52840.&nbsp;</p> <p>Best regards</p> <p>Bjørn&nbsp;</p><div style="clear:both;"></div>
