https://devzone.nordicsemi.com/f/nordic-q-a/24141/dfu我的手机APP会自动检测固件是否有更新，当检测到固件更新后，会进行DFU升级。 现在问题是，当升级进行中将手机APP强退，会导致程序停留在BOOTLOADER中，此时APP不会识别BOOTLOADER的蓝牙，不能继续升级。 我想在这种升级失败的时候直接进入应用程序，而不是停留在bootloader中，请问可以吗。 我使用的芯片为nrf52832 协议栈为13.0.0en-USTelligent Community 13Tue, 08 Aug 2017 12:58:24 GMThttps://devzone.nordicsemi.com/thread/95053?ContentTypeID=1Tue, 08 Aug 2017 12:58:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2e369dd4-1a86-40f7-a76f-9dc0e57769e0Hung Bui<p>Thanks Roger for the Google translation. It&#39;s still not clear what exactly the problem was. @Stefanie: Please describe, better in English, how you tested. What exactly happened when the problem occurs.

The reads</p> <p><strong>DFU upgrade failed to enter the application after the problem</strong></p> <p>My mobile phone APP will automatically detect whether the firmware update, when the detection of firmware updates, will be DFU upgrade. Now the problem is, when the upgrade will be in the mobile phone APP strong retreat, will cause the program to stay in BOOTLOADER, APP will not recognize the BOOTLOADER Bluetooth, can not continue to upgrade. I would like to directly in this upgrade when the failure to enter the application, rather than stay in the bootloader, may I ask you?</p><div style="clear:both;"></div>
