 we have to use BLE based DFU. Our Bootloader ist SDK11 based, so we just have the bootloader API V1.0 available. 
 10.000 devices are in stock, so we cannot change anything related to the bootloader. Now we enter the bootloader using a Python script</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Fri, 21 Feb 2025 13:35:02 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/119159/using-dfu-via-ble-with-bootloader-api-v1-sdk11" /><item><title>RE: Using DFU via BLE with Bootloader API V1/SDK11</title><link>https://devzone.nordicsemi.com/thread/524096?ContentTypeID=1</link><pubDate>Fri, 21 Feb 2025 13:35:02 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:4400c11d-2819-4277-9d3c-4aad10ee6cc1</guid><dc:creator>Einar Thorsrud</dc:creator><description>&lt;p&gt;Hi Michael,&lt;/p&gt;
&lt;p&gt;The latest version of nrfutil with support for the legacy bootlaoder was nrfutil 0.5.2, so this is what you need to use to generate the DFU .zip file. However, this does not provide a way to perform DFU over BLE. Please see &lt;a href="https://devzone.nordicsemi.com/f/nordic-q-a/71486/which-version-of-nrfutil-for-legacy-dfu"&gt;this thread&lt;/a&gt; for more information.&lt;/p&gt;
