ESB - BLE uart timeslot problem - Timeslots stops being called

[MStampe]

Hi

I have implemented (heavily base on the found examples) an application which uses both ESB and BLE.
For now I focus on developing the ESB part of the SW.

I am using the SDK 15.2.0 and developing for a NRF52832 using Segger.
The softdevice is the newest S132.

It actually works quite well, but my main problem is that my timeslot-interrups only occurs as long as the BLE is advertising or if there is an ongoing connection.
So the default advertisement timeout is 180 seconds, after this the interrupts-doesn't occur anymore.

I have found others with this problem, but either their solution is just to restart advertisement, or else they didn't write you back here at the forum.

Sometimes I need to use ESB without using the BLE part.
In general I cannot find very much documentaion about how the ESB and BLE are related regarding the timeslots?

Hope you can help figure this out.

Best regards

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.

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.

Can you share your project?

[MStampe]

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

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.

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

[MStampe]

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.
