How not to use the init packet in DFUhttps://devzone.nordicsemi.com/f/nordic-q-a/5642/how-not-to-use-the-init-packet-in-dfuI am changing my project from 6.x to 7.x, and I saw in the BLE Bootloader/DFU documentation that there is a point in the bootloader where it decides weather to use the init packet or not, but I cannot find that place.

I am trying to change the source code of Bootloader from SDK v7.1.0 to avoid initdata packet checking such that I can do a FOTA without selecting an init packet from the Master Control Panel.</p> <p>I tried modifying the functions dfu_init_pkt_handle and dfu_init_pkt_complete in dfu_dual_bank.c but I still get INIT Packet required message in the MCP app.</p> <p>Could you tell me what changes are required more to make it run?</p><div style="clear:both;"></div>RE: How not to use the init packet in DFUhttps://devzone.nordicsemi.com/thread/19757?ContentTypeID=1Fri, 20 Feb 2015 09:49:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:892fa17c-1990-4b46-b910-644ca7531e93Hung Bui<p>Hi Antonio,</p> <p>From SDK v7.x Initdata packet is obligated as you can see <a href="http://developer.nordicsemi.com/nRF51_SDK/doc/7.2.0/s110/html/a00071.html#ota_intro_section">here</a> (it&#39;s not optional as in SDK v6.x).</p> <p>If you want to avoid initdata packet you would need to modify the source code of the bootloader.</p><div style="clear:both;"></div>
