Challenges that makes me hesitate to vote:

I ran into there error discussed here: devzone.nordicsemi.com/.../ Sarah's answer worked. The challenge is I spent more time than I should figuring this out.
The GitHub readme is still poorly documented. It should be updated with the info you provide.

Does it make sense to fix these? If so I will then vote.

yes, indeed. It was great to get this working. Now I am not sure about using the newer SDK :-)

Now, with SDK 8.0.0, it works!!!

I'm also facing the same problem that 'vojc0008' described above with "L6128E...." errors. Which is the solution to go ahead? You said you already have the solution. Which is this one?

Best regards.

I am also have this (frustrating) issue. Can you please update steps/procedures so that we can make progress?

the project compiles but the linker doesn't want to play:

I have the very same issue. This is really getting frustrating. No matter what you try, there's always a new set of errors. Can anyone please post a step-by-step explanation how to make this work?

What was the solution the Nordic employee gave you in the end? I am stuck trying to get the same thing going. I've unzipped to C:\Keil_v5\ARM\Pack\NordicSemiconductor\nRF_Examples\8.0.0\ble_peripheral\nrf51-ble-app-lbs-SDKv8.0 Loading and trying to build this results in a raft of errors caused by broken links. I tried copying to my own projects folder C:\Projects\firmware\nRF51\nrf51-ble-app-lbs-master and then selected applicable software packs (though I don't know what versions to use of each, for example do I use RF libraries v 2 or 3?) and this did not work...

A local Nordic employee helped me get this rocking now. Thanks for also helping. Great to know there's good support around. I am now moving forward and have my custom PCB working very well now with LEDs and PWMs. Buttons and the DFU are the last two things to get working.

Why is the "nrf51-ble-app-lbs" not included in the examples? Or am I not finding it? I can compile all the other examples just fine but if I place the "nrf51-ble-app-lbs" in the folder "\examples\ble_peripheral" I still get errors. Has anyone been able to get this to compile? This should be so simple I figured it would be in the SDK examples but it is missing. I have added the GCC folder to the includes to remove the CM0 error.

Now I get the following errors:

._build\ble_app_lbs.axf: Error: L6218E: Undefined symbol nrf_drv_gpiote_in_event_disable (referred from app_button.o).

._build\ble_app_lbs.axf: Error: L6218E: Undefined symbol nrf_drv_gpiote_in_event_enable (referred from app_button.o).

@wojc0008: You can download the SDK .zip file here And simply unpack it, and you will have the folder structure needed to compile the lbs project. You don't need to unpack it to KEIL folder. Don't forget to match the project with the SDK version. (nrF MDK v7.2.0 is recommeded to use with KEIL v5.14)

Which one would you recommend? I have tried including all the files and folders so the linking is all correct now. I am getting tons of errors still though. See below. Does anyone have a simple example that has all the files in the project instead of linking to different directories? I have a feeling it is linking to previous SDK versions on accident.

What version of the SDK are you using? You can select an older SDK by clicking on the branch drop down.

Edit 18.05.2015: In general I would recommend you to use the latest SDK, version 8.1.0, but the latest ble_app_lbs example made with SDK 8.0.0. So if you want the example to work out of the box you should use SDK 8.0.0.

Edit 08.06.2015:

Step by step:

Download SDK version 8.0.0 zip(nRF51_SDK_8.0.0_5fc2c3a.zip) from here.

Unzip to C:\Keil_v5\ARM\Device\SDK8.0.0 (SDK8.0.0 folder must be made)

Go to the nrf51-ble-app-lbs example on GitHub and select the SDKv8.0 branch.

Unzip it to C:\Keil_v5\ARM\Device\SDK8.0.0\examples\ble_peripheral

Open ble_app_lbs.uvprojx in C:\Keil_v5\ARM\Device\SDK8.0.0\examples\ble_peripheralpemy\nrf51-ble-app-lbs-master\arm and compile.

Edit 09.06.2015:

The readme in branch SDKv8.0 now contains a How to get started
