https://devzone.nordicsemi.com/f/nordic-q-a/12227/two-way-relayHello all, I use the relay function of the S130, and want to do a two-way data communication. I can relay the data of peripheral to central with sample code. peripheral(Slave) -&gt; relay(Master-Slave) -&gt;central(Master) However, I will not be ableen-USTelligent Community 13Tue, 01 Mar 2016 10:33:45 GMThttps://devzone.nordicsemi.com/thread/46263?ContentTypeID=1Tue, 01 Mar 2016 10:33:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3eeffa67-cc21-41b6-acaf-0380096e4ce9FormerMember<p>There is an example on github with a two-way relay, you can find it <a href="https://github.com/NordicSemiconductor/nRF51-ble-app-hrs-s130/tree/master/ble_app_hrs_c_s130_1_0_0-3-alpha">here</a>. The example has not been updated to use the latest version of the softdevice, nor the lastest version of the SDK, but it should give an idea of how to make a relay in both directions. The description of how the example works is placed in the top of main.c.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/46262?ContentTypeID=1Tue, 01 Mar 2016 10:08:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:136055ae-6044-4e43-8981-4c67bb133e66endnode<p>Well there should be no issue, if you know to transport the information one way you also know the other, they are symmetric. Where is the problem?</p><div style="clear:both;"></div>
