How do I use softdevices in nRF52?

[tj.park]

I want to implement BLE using nRF52840.

Without using SDK, we have formed a new project and successfully controlled GPIO control and UART.

She wants to use the Softdevices API here.

How should I use it with the IAR compiler?

Hi, 

Which version nRF5-SDK would you use? The latest version is nRF5 SDK v17.0.2 which supports IAR Workbench 7.80.4. You can duplicate the IAR project under nRF5_SDK\examples\ble_peripheral\ble_app_template\pca10056\s140\iar as the base to develop.
