Hi Robin,

have you looked at the bootloader example from the nRF51822 SDK? It cannot be used directly on the nRF51422 yet, but it might serve as a reference for you. It includes two ways of transferring the updated image, serial transfer (UART) and over-the-air (BLE).

The nRF51422 SoftDevice is being updated to offer the same bootloader functionality as the nRF51822 one. Once that happens, the nRF51822 bootloader example will be directly applicable. When this update is released you might have to get a updated silicon revision of the nRF51422 though..

So does it mean i can not write a uart based boot loader for nrf51422? until you guys update the soft device ?
