https://devzone.nordicsemi.com/f/nordic-q-a/43801/ble-conectionless-and-dfuHi, We are currently working on a project involving a few Connectionless BLE advertisement transmitters based on nRF52832 (SoftDevice 6.1.0). On the receiving end we have an nRF52840. Now we are investigating the possibility to implement DFU in thisen-USTelligent Community 13Mon, 18 Feb 2019 16:35:14 GMThttps://devzone.nordicsemi.com/thread/171710?ContentTypeID=1Mon, 18 Feb 2019 16:35:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:da3cb997-a850-4feb-83a3-e0240b511023Vidar Berg<p>Hi Mats,</p> <p>It is not a problem to switch to connectable advertising on the fly, but you need a way to signal the peripheral to switch mode, which may be difficult if your not in a connection or have physical access to the device. Is DFU going to be initiated by the receiver, or by an user with a smartphone,etc? &nbsp;</p> <p>Regards,</p> <p>Vidar</p><div style="clear:both;"></div>
