how to FLASH upgrade FW in the nRF51822 though my application controller?

want to FLASH upgrade FW in the nRF51822 though my application controller. Is C or C++ code available for this operation or can you deliver a protocol description how to setup this ?

  • In SDK 4.3.0 there is a UART bootloader that can be used to upgrade the application on the chip. Have you taken a look at it? We don't really have any other code than this, but it should be sufficient if you need to replace the application running on the nRF51822.
