How to use the softdevice (S140-SD-v6) with SDK (14.2.0)??

Hi,

    I'm trying to run some examples using my nRF52840. I noticed that the BLE header files used in the SDK 14.2.0 are different than what's in the standalone S140 (6.0.0-6.alpha). For instance, these two ble_gap.h files have a lot differences including the advertising parameters struct ble_gap_adv_params_t:

1. s140_nrf52840_6.0.0-6.alpha_API/include/ble_gap.h (S140-SD-V6)

2. nRF5_SDK_14.2.0_17b948a/components/softdevice/s140/headers/ble_gap.h (SDK 14.2.0 )

   For the ble_app_uart_c example from the SDK, I compiled and flashed the SD and App to the nRF52840 board and verified the results from a JLinkRTTClient. But since this project is using related header files in the components/softdevice folder, I made some changes to the Makefile so that it could compile with the new API inS140-SD-V6, I made some changes to the ble_app_uart_c example. First, I replaced the hex file used in the flash_softdevice target to the hex file in the S140-SD-V6. Compiled and flashed, it got me a fatal error. Then I tried to replace the  $(SDK_ROOT)/components/ble/ble_services/ble_hrs \ and $(SDK_ROOT)/components/softdevice/s140/headers/nrf52 \ to the corresponding headers in the S140-SD-V6. Didn't work either. It seems the standalone softdevice is different in length than the one in the SDK14.2. I'm not sure if that is the problem. 

   What should I change instead to make this work?

   I'm using a linux environment with Eclipse Oxygen and arm-none-eabi-gcc 7.2.1.

   Thanks!!

Hi, my recommendation in this case is wait until Monday when SDKv15 with SDv6.0 (production version) is relased. The issues you are currently experiencing is likely due to different alpha release used between SDK and SD, in any case you should use the production version that will be ready on Monday.  I would also like to mention that our SDK are not delivered with Eclipse support, so instead you should consider using SEGGER embedded studio (free commercial license for Nordic ic and gcc compiler):

Then all the examples will work straight away.

Thanks Kenneth.

I'll try the SEGGER IDE. Is there any way to experience the Bluetooth 5 advertisements with the current SDKv14 in my setting?

either way, looking forward to the SDKv15 release next Monday!
