https://devzone.nordicsemi.com/f/nordic-q-a/47288/how-to-make-dongle-restart-application-rather-than-go-into-bootloader-mode-in-response-to-resetIn my application, the nRF52840 dongle is hard-wired via UART port pins to the UART interface of a Wi-Fi gateway host board. I need the nRF52 application to restart when it receives a RESET from this host board (not go into USB bootloader mode) USBen-USTelligent Community 13Wed, 15 May 2019 08:38:50 GMThttps://devzone.nordicsemi.com/thread/187154?ContentTypeID=1Wed, 15 May 2019 08:38:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:26c7c88b-8584-4ad1-8cb1-7c745d44559fSimonr<p>Hi Peter</p> <p>Might I suggest to make the Dongle go into system off mode (and then system on) when the reset signal is received? As this should keep the dongle from going into bootloader mode, while the button will still work.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
