frozen.h is missing std libraries, DebugPrint.c is missing std libraries, Fifo.c is not included in the project, etc.

I suggest you install SES on another machine and try building your provided project. You should experience the same issues.

Hi again

Hmm that is very weird.
I am using the Segger ES 3.52a.

I just tried again downloading the shared project and compiling it from scratch, no problems.

Hey I'm afraid I still can't compile.

In frozen.c you've missed stdint.h, I get compile errors because int64_t and all other basic types are undefined. This is true for a lot of the source and header files.

I do not understand how you can compile without the necessary standard libraries included in your compilation units, though I'm not that familiar with CPP and its preprocessor and compilation units.

What version of Segger ES are you using?

Ohh sorry, seems to only be one missing reference missing.

I have now added this missing fifo. At least I can compile it out of the box using Segger.

I'm afraid I'm not able to compile your project. There are too many dependencies that are not in order.

Hi Haakonsh

I have created a project, which just have the most important parts in it, to show the problem.
I have in the root added a file descriping the project and the problem. "Brief desciption of project.txt"

You can find it here:

Looking forward to you answer.

Unfortunately I cannot.

I can create an example project, that shows the problem with the setup we have, but it will take a couple of days before I got that.

I was hoping that you knew what the problem was related to 🙂

Can you share your project?

Hi Haakonsh

No, unfortunately this is not the case. All the software is running just fine, only the timeslot interrupts are not happening. As you see in link provided, I have the same problem.

It's very clear that is stops as soon as the advertising stops. I have in the event handler tried to remove the SystemOFF call. That don't make a difference. The only think keeps the timeslot IRQs trigging is to restart the advertisement again.

I need to say that is our own software running, but a very boiled down version, with only ESB usage and the BLE uart running. Where the BLE uart is almost taken directly from the examples found here.

You're probably going into SystemOFF after the advertisements time out, and that's why your Timeslots are no longer availlable.

See the advertising event handler in main.c.
