How do I use softdevices in nRF52?https://devzone.nordicsemi.com/f/nordic-q-a/67177/how-do-i-use-softdevices-in-nrf52I 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?en-USTelligent Community 13Wed, 14 Oct 2020 09:05:31 GMTRE: How do I use softdevices in nRF52?https://devzone.nordicsemi.com/thread/274826?ContentTypeID=1Wed, 14 Oct 2020 09:05:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:75ee1d65-a194-456c-9690-b03c26eaf2b0Amanda Hsieh<p>Hi, </p> <p>Which version <a href="https://www.nordicsemi.com/Software-and-tools/Software/nRF5-SDK/Download#infotabs">nRF5-SDK</a> <span style="font-family:inherit;">would you use? The latest version is </span><a style="font-family:inherit;" title="nRF5 SDK v17.0.2" href="https://infocenter.nordicsemi.com/topic/struct_sdk/struct/sdk_nrf5_latest.html?cp=7_1">nRF5 SDK v17.0.2</a> 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. </p> <p>-Amanda H.</p><div style="clear:both;"></div>
