If you want to connect to the device from remote, you also need IPv6 support from your ISP. It is also possible to setup an IPv6 over IPv4 tunnel, to be able to communicate with the device without hardware support for IPv6.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/73893?ContentTypeID=1Thu, 19 Jan 2017 14:50:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:62a8fe67-8825-47b3-b747-747f34a381d4nav87<p>Yes i am able to ping nRF52 from Rpi.
