CC2340R5: Zephyr DIS Exp

Hello Jim,

Thanks for reaching out.

I am working on trying to reproduce the issue. The repository has been updated very recently, could you please update your local branch and try again.

I only get one warning when building: No SOURCES given to Zephyr library: drivers__entropy.

In addition, could you please try flashing with XDS using a .hex file?

BR,

David.

Hi David - Thanks for reaching out.  I have been trying a few things today.

-Flashing with Uniflash and XDS.  This had no effect on the issue.

-Local branch version.  I just setup the simplelink-zephyr last week.  I used the tag "v3.7.0-ti-8.20.01_ea" in the west init command.  This is the latest version.

-The warning about the function bt_tx_irq_raise().  I did a search for this function.  I can find it in the hci_core.c file (in the ../subsys/bluetooth/host folder).  However, I do not find it in any header files.  It's kind of an odd case.  The file diff for commit:ea816e6/tag:v3.7.0-ti-8.20.00 shows the declaration being removed in hci_core.h, but the previous commit/tag (ed5d059/v3.7.0-4eb8fa603cf-ti-8.20.00_ea) does not have the declaration.  So, it seems like this was inserted during development, but then removed.  If I add the declaration back in.  The code compiles with no warnings.  However, the issue remains where the phone connects, but cannot retrieve the characteristics of the DIS, and then disconnects.

My other thought is perhaps some other tool is the wrong version.  Pasted below is the full output out of the build.

Hello Jim,

For a quick sanity check, may we do a fresh installation of the latest release? Please make sure to follow the steps in https://github.com/TexasInstruments/simplelink-zephyr/tree/v3.7.0-ti-8.20.01_ea and https://docs.zephyrproject.org/3.7.0/develop/getting_started/index.html, especially considering the required minimum versions of the libraries and the following note in the TI ReadMe?

NOTE: When running west init in the getting-started guide it's important to instead run west init -m https://github.com/TexasInstruments/simplelink-zephyr --mr {tag-name} zephyrproject in order to use the TI Zephyr repository. The {tag-name} changes with each release from TI.

BR,

David.

Hello David -

No luck, unfortunately.  I've pasted all the commands below.  Note, I did change a couple of things from the previous install.  Switched to Python 3.11 vs 3.12 as there is a note in the Zephyr Getting Started about 3.12 not being recommended.  Switched to Zephyr SDK 0.16.8 because 0.17.0 is not listed as compatible for Zephyr 3.7.

I'm going to try this on a different PC as well.  I will let you know.

-Jim

Flashed with both UniFlash/XDS and Segger JLink. No difference

Hello Jim,

I will try to reproduce this on my end again and come back to you tomorrow max. Please bear with me.

May I ask if you are executing west zephyr-export? I don't see it in your previous steps.

BR,

David.

Hi David - Yes, I did.  I post documented the steps and realized I made errors in that process.  I originally copied only the command, but later added the Command Shell prompt to show the location.  However, in that step I also marked some of the prompts as (.venv) when they were not.  Sorry for the poor documenting.

Hello Jim,

Apologies the delay. I am trying to reproduce your scenario however I do not end up with the same warning. Please allow me until tomorrow to try with a fresh setup.

BR,

David.

Hello Jim,

I have done a clean installation, I was able to reproduce the issue and I am working on the problem you are referring to. So far I see the device stops executing any type of BLE task after the central attempts a gatt discovery and remains in idle.
