https://devzone.nordicsemi.com/f/nordic-q-a/35439/ota-dfu-from-nrf52-to-nrf52Dear all, maybe I‘m missing something, but I know there are OTA DFU client libraries for Swift, ObjC, Java and Python. But it looks like there is no DFU lib from one nRF52 to another in C or C++ - is that correct?en-USTelligent Community 13Mon, 18 Jun 2018 06:58:44 GMThttps://devzone.nordicsemi.com/thread/136475?ContentTypeID=1Mon, 18 Jun 2018 06:58:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a479bd14-8523-4e1c-b1a7-747d14cc99bfH&#229;vard<p>Hi,</p> <p>You are correct. Currently, there is no &quot;nRF52 to nRF52&quot; setup provided in our SDK. To be more precise, there is no DFU client implementation to go with the existing DFU server implementation.</p> <p><a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/lib_dfu_transport_ble.html">Although the transport layer is defined</a>.</p><div style="clear:both;"></div>
