Great to here Jim! I am also unsure why this fixed your problem. Maybe something with the mbed driver? But anyway good to here that you solved your problem!

@Bjørn Kvaale I have got the nRF52DK working now with the Mbed drag and drop method. I had to use a windows PC with a clean install of windows 10 (not an upgrade from windows 7) and now I can drag and drop Mbed hex files to the board, and the code executes perfectly. I don't know why this fixes the problem.

Check out this link. Flash the softdevice (S132) to your chip and then build & download the ble_app_hrs app to your nrf52. Then, open up the nrf Toolbox app and run the HRM (heart rate monitor) app. Press Connect & you should see the DEVICE_NAME of your nrf52 given on line 80 of the main.c file.

@Bjørn Kvaale I can upload the ble_apps hrs hex to the nRF52DK using nRFGoStudio and LED1 flashes on the board. I do not know what this code is supposed to do exactly, as there is no readme file in the SDK.

@Bjørn Kvaale When I upload the mbed blinky hex either by dragging or dropping or via nRFgoStudio none of the LEDs light up. But if I upload the blinky hex from the SDK via nRFgoStudio it works well. I will try and flash the ble_apps hrs hex file now and report back to you shortly.

I believe I had the same bug as you. The Blinky example would just turn on LED1, but the led would never start blinking. I will double check with some colleagues to see what the problem is. Have you tried to flash the ble_apps hrs hex file to the nrf52dk using nrfGoStudio? Does that work?

@Bjørn Kvaale I can program the nRF52DK using the method you have described and I can see the blinky example working that was included in the SDK. However, the Mbed blinky hex file does not make the LED flash even though it nRFGoStudio says it weas programmed correctly. So I still have no way of programming my nRF52DK from with hex files from the mbed compiler on a windows machine.

What if you try to flash the blinky hex file using nrfGoStudio instead? Is that a possibility or do you absolutely want/need to use the mbed program? You can take a look at this tutorial. Just ignore the fact that the tutorial requires nrf51 and keil. Flash the softdevice (you will probably need the S132) first, and then flash the blinky hex file (under nRF5_SDK_14.0.0_3bcc1f7\examples\ble_peripheral\ble_app_blinky\hex) in the Program Application tab in nrfGoStudio.

I am also running Windows 10 and I have flashed both the Blinky and the ble_apps_hrs hex file to my nrf52 using nrfGoStudio. The hrs example worked very well when I connected the nrf52 to the nrf toolbox app for iOS (also available for android). Then you can run the HRM application. Hope that helps!

Thanks @Bjørn Kvaale I have tried it on 3 different windows 10 machines and they have the same problems even with the mbed serial port drivers installed.

Weird that it works on mac, but not windows. I'll take an in depth look at this issue next week.

@Bjørn Kvaale I am just using the mbed compiler and then drag and drop to the hex file to the nRF52 DK mbed external drive.

What IDE are you using? Are you using the ARM or Nordic SDK toolchain?
