![]() In the Devices tab, search for and select the target device, "nRF51822_xxAA" so that the related packages appear in the Examples tab. It is a good idea to click the "Check For Updates" button to update Pack Installer beforehand. In Pack Installer, software packages necessary for the target board to be developed can be installed. When Keil µVision IDE first starts, Pack Installer launches. But, then, the system does not have any Nordic SDKs installed. Once installed, Keil µVision IDE is installed with ARM CMSIS and such. Step 1: Software Installationĭownload MDK-ARM v5.26 or later from ARM KEIL and install it in Windows 10. Run the app on a mobile phone (Android)Īll the information are obtained as of September 28, 2018. ![]() The procedure contains the following steps. I found out that my nRF51822 board is "nRF51822_xxAA" which has 256kB ROM (program memory size) and 16kB RAM (the 2nd image). So, a power supply may have to be prepared when using a ST-Link device because some of ST-Link devices seem not to have a capability of powering up a microcontroller. The programming of the ble_app_hrm application which is provided from Nordic's SDK is presented here.Īnd as shown in the 1st image, ST Nucleo-F401RE, Waveshare BLE400 and nRF51822 Board have been used, but BLE400 is not necessary as far as you can connect ST-Link and your nRF51822 board.Īnd the advantage of using ST-Link on Nucleo has been taken to supply the power of 3.3 or 5V to the nRF51822 board. ![]() This describes what makes me struggle to implement a "Softdevice" example app onto the board. Here, thus, I would like to note what I have gotten through. When I started to develop a nRF51822 application for my hobby project, I found that there was not organised information on this topic.
