https://devzone.nordicsemi.com/f/nordic-q-a/63169/device-firmware-updateHello , Is there a DFU master code through which one nrf52832 can be updated from another nrf52832. If not please let me know of some useful material to refer to implement this feature.

I had gone through this , I was looking for master code via BLE. I assume there is not a DFU master code via BLE.&nbsp;</p> <p>Thanks and Regards</p> <p>Dilip</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/257560?ContentTypeID=1Tue, 30 Jun 2020 11:56:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:94a20253-0351-49e9-a7ec-4e74ca35aca8Amanda Hsieh<p>Hi Dilip,&nbsp;</p> <p>Please see&nbsp;the&nbsp;<a href="https://devzone.nordicsemi.com/nordic/short-range-guides/b/software-development-kit/posts/getting-started-with-nordics-secure-dfu-bootloader#h108sjziaxo3m81rkgr1has5r1d72qtu">DFU Master code</a>&nbsp;example.&nbsp;But it&#39;s only SPI and UART, not BLE.</p> <p>-Amanda H.</p><div style="clear:both;"></div>
