https://devzone.nordicsemi.com/f/nordic-q-a/77324/dfu-without-nrf-connect-pc-ble-driverI need to do batch DFU updates, and the pc-ble-driver/nRF Connect Firmware combo is too unreliable for my needs. I would prefer to just use the wireless transciever built into my laptop. Does Nordic have a tool for this? If not, is there documentationen-USTelligent Community 13Mon, 12 Jul 2021 15:51:13 GMThttps://devzone.nordicsemi.com/thread/319660?ContentTypeID=1Mon, 12 Jul 2021 15:51:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4d35edaa-10d6-40a8-8af8-ffb0a9a69676Hung Bui<p>Hi Evan,&nbsp;</p> <p>We currently don&#39;t have an example code for doing DFU from the native BLE interface on PC. We do have<a href="https://github.com/NordicSemiconductor/Android-DFU-Library"> example code </a>for doing DFU from mobile phone both iOS and Android that you may refer to.&nbsp;<br />Other than that you may need to study the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/lib_dfu_transport.html?cp=8_1_3_5_2">DFU interface</a> and write your own code.&nbsp;<br />I haven&#39;t written the BLE DFU master code but I did make a DFU master code for SPI. You can have a look <a href="https://devzone.nordicsemi.com/nordic/short-range-guides/b/software-development-kit/posts/getting-started-with-nordics-secure-dfu-bootloader#h108sjziaxo3m81rkgr1has5r1d72qtu">here</a>. Hope that helps.&nbsp;</p><div style="clear:both;"></div>
