https://devzone.nordicsemi.com/f/nordic-q-a/22749/nrf51822-repeater-range-extenderHello, is the nRF51822 able to function as repeater or range-extender, repeating BLE signals from explicit two BLE devices (with known addresses)? I know there are specific devices for this, but i can&#39;t find a reason why it shouldn&#39;t work.

Or am I missing something?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/89429?ContentTypeID=1Tue, 13 Jun 2017 14:06:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:efb72495-38fb-49e0-a554-72abde4ba77dhberg<p>Sorry, i mean relay / range-extender without looking into the packets. I need to know if it is possible to repeat any kind of BLE packet (ADV_IND, CONNECT_REQ, ...). It should just retransmit any packet it hears.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/89428?ContentTypeID=1Tue, 13 Jun 2017 13:42:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:35ec243a-3807-4234-a5a7-531dd3d60e14Sigurd<p>Hi,</p> <p>Yes, this is possible. Take a look at the <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.3.0/ble_sdk_app_rscs_relay.html?cp=4_0_1_4_2_1_1">BLE relay example</a> in the SDK.</p> <p>You can find the source code and the project file of the example in the following folder:</p> <pre><code>&lt;SDK_InstallFolder&gt;\examples\ble_central_and_peripheral\experimental\ble_app_hrs_rscs_relay </code></pre><div style="clear:both;"></div>
