DFU Service with readback protection

Can DFU Service update the SoftDevice, Application, and/or Bootloader if readback protection is set to ALL?

  • In the nRF51 Series Reference Manual Version 3.0, Section 8.1 it states...

    "Code running from code region 1 will not be able to write to code region 0."

    I'm assuming this means that only region 0 is protected. Since the bootloader for the DFU service is located in region 1 then I would assume the DFU Service would not work. I wanted to make sure, because it is not clear why a readback protection would prevent me from writing.
