    The nRF51822 chip is shipped without pre-programmed software. This gives you the option of developing your application directly onto the chip or alternatively, by using our S110 nRF51822 SoftDevice, which is a Bluetooth low energy peripheral protocol stack solution. For more information, see the S110 nRF51822 SoftDevice Specification.
  • Page 34 6.1.2 Identifying the nRF51 chip and chip content When you select a board, nRFgo Studio identifies the nRF51822 chip and how its memory is organized. The following chip and memory information is displayed: • nRF51 chip identification - Identifies the chip by name and code variant (for example, nRF51822 QFAACA).
  • Page 35 4. Set the SoftDevice size. This sets the size of the code memory region 0 and will not be available if the size is defined by the HEX file. Note: The S110 nRF51822 SoftDevice can be downloaded from www.nordicsemi.com by logging into your MyPage account and entering the product key printed in the Development Kit.
  • Page 36 Development Kit User Guide v1.4 6.1.5 Programming an application This function lets you program an application onto the chip. Before nRFgo Studio starts programming it verifies that the HEX file matches the actual memory configuration. If it matches, nRFgo Studio continues with the programming, if not it stops the programming and returns an error message.
