https://devzone.nordicsemi.com/f/nordic-q-a/40811/fast-custom-mesh-over-ble-gattHave a nice day! We are working on a project where goal is to build up mesh-network up to 50 nodes with high sum data rate to up 100kbps through the node. For this purposes conventional ble-mesh or even 6lowpan over thread aren&#39;t suitable.

We did not yet optimize it for throughput, but we have some open tasks where we are trying to improve that. It should serve you as a good starting point.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/159298?ContentTypeID=1Tue, 27 Nov 2018 16:25:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d092a300-ae02-4aec-9a7b-584ce8db6774Mttrinh<p>Hi,</p> <p>Yes, it is possible for the&nbsp;<span>nrf52840 device to have several conncetions concurrently. I suggest you have a look at this <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/ble_sdk_app_rscs_relay.html?cp=4_0_0_4_1_1_2" rel="noopener noreferrer" target="_blank">example</a>. Also, have a look at <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/ble_sdk_app_multilink.html?cp=4_0_0_4_1_0_2" rel="noopener noreferrer" target="_blank">this</a>&nbsp;and <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/ble_sdk_app_multiperipheral.html?cp=4_0_0_4_1_2_25" rel="noopener noreferrer" target="_blank">this</a>&nbsp;example.</span></p> <p>Unfortunatly, we haven&#39;t tested how the throughtput are affected by the increasing number of connections. I would suggest you start with the example mentioned above and see if the throughput is enough.</p> <p><span>&nbsp;</span></p><div style="clear:both;"></div>
