Current consumption before flash bootloader is 200uA, but when i flash bootloader it increase 1.2mA. How do i disable bootloader?en-USTelligent Community 13Mon, 23 Aug 2021 12:32:17 GMThttps://devzone.nordicsemi.com/thread/326194?ContentTypeID=1Mon, 23 Aug 2021 12:32:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:30137074-43dd-47a7-8dbc-76a847961ac8Amanda Hsieh<p>Hi,&nbsp;</p> <p>Our expert said 1.2 mA sounds like either UART in constant RX, or the SoC is in Debug mode. In that case, this has nothing to do with the bootloader.&nbsp;You should have a look at <a title="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/optimizing-power-on-nrf52-designs" href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/optimizing-power-on-nrf52-designs">https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/optimizing-power-on-nrf52-designs</a></p> <p>In particular, ensuring the debug interface is not running is point 1 under &quot;Debugging&quot; in that blog post. That said, Bluetooth mesh typically means staying in RX most of the time, so you should expect relatively high power consumption.</p> <p>What kind of mesh node is it? If it is a relay node, then the bootloader should not add any overhead.</p> <p></p> <p>Regards,</p> <p>Amanda H.</p><div style="clear:both;"></div>
