My product is based on nRF52840.
I have downloaded nRF5_SDK_17.0.2_d674dde.
Example: ble_central_and_peripheral / ble_app_interactive.
pca10056 doesn't have iar project.
I have tried tried to convert from Keil project (library arm5_no_packs), using EWARM_MigratingFromKeil.ENU.pdf.
It is not clear how to use the project converter.
