https://devzone.nordicsemi.com/f/nordic-q-a/47772/nrf52840-as-a-border-routerHello, We have started to design a project and we would like to use the Nrf52840 as border router with a linux terminal. The link would be a serial over USB. So the NRF52840 will embed the USB stack. But it will be also a border router supposed to handleen-USTelligent Community 13Mon, 27 May 2019 13:55:39 GMThttps://devzone.nordicsemi.com/thread/189365?ContentTypeID=1Mon, 27 May 2019 13:55:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ba64b14d-e537-4161-b211-43797bd2c9f7J&#248;rgen Holmefjord<p>Hi,</p> <p>I think this should be possible. As far as I know, we have not done any tests with USB and 20 concurrent connections, but the <a href="https://github.com/NordicSemiconductor/pc-ble-driver#compiling-connectivity-hex-files">connectivity FW</a> we use with pc-ble-driver and nRF Connect already support USB and 8 connections as a peripheral and 8 connections as a central. You should be able to easily modify the application to build it with support for 20 connections, and test if it works as expected (see line 64476-64486 of <a href="https://github.com/NordicSemiconductor/pc-ble-driver/blob/master/hex/nRF5_SDK_15.3.0_connectivity.patch">this file</a>).</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
