https://devzone.nordicsemi.com/f/nordic-q-a/56430/how-do-i-use-dfu-control-point-characteristicsHi, I am trying to send firmware image from one board to another board. For that I want to use DFU control point characteristics. I am using nrf52832 development kit and SDK 15.3. Is there any example available that I can refer to for this? en-USTelligent Community 13Mon, 13 Jan 2020 15:08:15 GMThttps://devzone.nordicsemi.com/thread/228858?ContentTypeID=1Mon, 13 Jan 2020 15:08:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:36936d91-9b2b-4590-a834-01eb166267a1Einar Thorsrud<p>Hi,</p> <p>You write about the&nbsp;DFU control point characteristic specifically (which is one of the two characteristics in the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/lib_dfu_transport_ble.html">BLE DFU service</a>), but I assume you are looking for complete that implements a BLE DFU master on the nRF Side? Unfortunately, nordic does not provide any such implementation. You can refer to the protocol documentation to implement it yourself, though.</p> <p>What is the use case for this?</p><div style="clear:both;"></div>
