I am working with nrf51, SDK 11, S130, Keil uVision 5 and have an Application with RTX and want to use DFU OTA. The bootloader works with the app_hrs_dfu example.
When starting the bootloader from my app, the bootloader is starting (LEDs are set), but the transfer doesn't start.
Do I have to stop RTX first? And how? How must the memory layout be? Is there a given order of the characteristics used? Can I reuse the running stack or do I have to restart?
Many thanks from some hints. Chris
