Issue trying to run a program from Segger embedded studio

[Gerardo Martin]

Hello all,

I am trying to use my nRF52832 DK for a wireless camera shutter for my phone. I have reviewed the example code from SDK 15.3.0 named ble_app_hids_keyboard as well as modifications to this code to include volume control. 

link to GitHub that modifies SDK 15: https://github.com/Rallare/nrf51_ble_app_hids_kbd_consumercontrol/tree/SDK15

When I try to build and run the example code in Segger embedded studio I have problems connecting my iPhone to the board via Bluetooth. However, I can use the hex files just fine by dropping those files in the external J-LINK drive window. I am not too familiar with hex files; I don't know where they come from but I know they can upload code to my board. The example code from the SDK works fine on my iPhone only if I upload the hex file. Does Segger embedded studio make these hex files/where do they come from?

I bring up the modifications because I want to build, and run those new volume controls with the example code from SDK. The GitHub repo doesn't include hex files so I'm not sure how I can continue working on this without fixing this problem. If you have any suggestions regarding Segger embedded studio or how to incorporate the volume control modifications to the example SDK code I would really appreciate it.

Hi,

The hex file is the output from the build process in SES. Usually we include the pre-compiled hex files with projects so that the end user doesn't need to build the project before they can flash the project to their nRF. 

When I try to build and run the example code in Segger embedded studio I have problems connecting my iPhone to the board via Bluetooth

 I just tried downloading the project and after building and flashing it to the nRF it worked without any issue! Does it build in SES without any issues for you? You might need to shorten the project name as Windows has a maximum length on path. 

Also, if you're new to SES then I suggest watching this tutorial.

regards

Thanks for your reply.

SES will build and run the project just fine but with Bluetooth connection problems to my iPhone. Again, the hex files work perfectly fine. A problem that I am having now is SES will not recognize my nrf52 DK anymore. I get "No emulators connected via USB" in a little menu asking to connect via IP instead.

I have been messing with this board in the arduino IDE, trying to flash a sketch (hid_camerashutter) built for an Adafruit nrf52832. I downloaded bsp for both adafruit nrf and nordic nrf. I burned the bootloader for the adafruit version to my DK and it worked. I probably shouldn't have messed with it but I did. I tried it again for the nordic bsp in arduino, burned the bootloader but now nothing works. :/ I can't upload any arduino sketches to my dk and SES won't recognize it. 

The J-link menu still pops up when I plug in my device and I've dragged the J-link OB SAM3U128 bin file in it to try to fix any problems but to no avail. 

Thank you for your help.
