https://devzone.nordicsemi.com/f/nordic-q-a/15422/nrf5-iot-sdk-v0-9-0-tcp-server-example---connection-refusedNeed some help on the tcp server example in the IoT SDK. All steps working but the python script gets Connection refused. bash# ifconfig bt0 bt0 Link encap:UNSPEC HWaddr B8-27-EB-FF-FE-1A-A7-41-00-00-00-00-00-00-00-00 inet6 addr: fe80::ba27en-USTelligent Community 13Mon, 26 Sep 2016 07:57:28 GMThttps://devzone.nordicsemi.com/thread/58852?ContentTypeID=1Mon, 26 Sep 2016 07:57:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ed653dda-0223-407f-a0a3-27327c91b32cStian R&#248;ed Hafskjold<p>Hi. The IP address <strong>fe80::ba27:ebff:fe1a:a741</strong> is the address of the <strong>bt0</strong> interface on your computer. You need to connect to the IP address of the nRF52 kit. As written in the Python example script:</p> <pre><code>#This example assumes the server BD address to be 00:AA:BB:CC:DD:EE and the used global prefix to be 2004::/64. #Therefore the global IPv6 address of the server will be 2004::02AA:BBFF:FECC:DDEE. </code></pre> <p>00:AA:BB:CC:DD:EE represents the address of the nRF52 kit. And you can work out the IP address by using the above &quot;formula&quot;.</p><div style="clear:both;"></div>
