https://devzone.nordicsemi.com/f/nordic-q-a/81980/flashing-nrf52833-over-bluetooth-using-the-nrf52840-pca10059Is it possible flash a nRF52833 over Bluetooth using the nRF52840 (PCA10059)? Or initiate DFU mode over Bluetooth using the dongle or a PC? How could this be achieved?en-USTelligent Community 13Tue, 23 Nov 2021 13:48:28 GMThttps://devzone.nordicsemi.com/thread/340357?ContentTypeID=1Tue, 23 Nov 2021 13:48:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e11430e1-e648-46d1-9002-fa266c18ab57Amanda Hsieh<p>Happy to help. <span class="emoticon" data-url="https://devzone.nordicsemi.com/cfs-file/__key/system/emoji/1f642.svg" title="Slight smile">&#x1f642;</span></p> <p>-Amanda</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/340350?ContentTypeID=1Tue, 23 Nov 2021 13:35:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e948ad25-1bdd-47c1-a6cb-b6e3e5d69cfcnrfquestion<p>Thank you</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/340318?ContentTypeID=1Tue, 23 Nov 2021 11:48:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:200dec01-d003-4d2c-a9e6-bdb229569475Amanda Hsieh<p>Hi,&nbsp;</p> <p>Have a look at&nbsp;<a title="Debug output" href="https://infocenter.nordicsemi.com/topic/ug_nrf52840_dk/UG/dk/hw_debug_out.html?cp=4_0_4_7_9">Debug output</a>&nbsp;section of the DK user guide.&nbsp;<span>Please make sure to provide the power both for the DK and chip board.</span></p> <p><span>-Amanda&nbsp;</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/340297?ContentTypeID=1Tue, 23 Nov 2021 10:38:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bdc83f19-f129-4607-be6a-19a06c4ad9b9nrfquestion<p>Thank you</p> <p>What would be the process once using a DK?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/340246?ContentTypeID=1Tue, 23 Nov 2021 07:55:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:424b04fd-ed9b-43d6-8cb0-adc267ce9f5aAmanda Hsieh<p>Hi,&nbsp;</p> <p>Since&nbsp;<span>nRF52840 (PCA10059) doesn&#39;t have&nbsp;the on-board debugger (OBD), it cannot program the chip. You need a DK which have&nbsp;the on-board debugger (OBD) such as <a href="https://www.nordicsemi.com/Products/Development-hardware/nRF52-DK">nRF52DK</a>, <a href="https://www.nordicsemi.com/Products/Development-hardware/nRF52840-DK">nRF52840DK</a>, <a href="https://www.nordicsemi.com/Products/Development-hardware/nRF52833-DK">nRF52833DK</a>.&nbsp;</span></p> <p><span>If you want to update via BLE DFU, it still needs to program bootloader to nRF52833 at first.&nbsp;</span></p> <p><span>-Amanda</span></p><div style="clear:both;"></div>
