Hi,
I am using keil uvision 5.17, SD 130, nRF 51822, dualbank bootloader.
I have programmed own application and merged bootloader, application, soft device.
I can do dfu as many as I want,
but the problem is I should push reset button whenever I finish dfu.
If I don't push reset button, I can't connect with smartphone.
My application have programmed from s130_hrs_with_dfu example,
I removed all of code exept dfu and device manage service.
