Supervision timeout does not expire during 120hz data streaming

chris.c

Hi,

I am using an two nrf5340 with hci_ipc enabled one acting as central and one as peripheral built on v2.9.0

The issue I am having is that the supervision timeout doesn't expire when I hard reset the peripheral whilst sending data (len 91) via notifications at 120hz .

My current fix is to set CONFIG_BT_ATT_LOG_LEVEL_DBG=y which then doesn't miss a supervision timeout event. This doesn't feel like a good long term solution to fixing whatever timing issue this is. Please could you help me.  

Problem Flow from Central perspective:

  1. Scan and connect
  2. Characteristic and CCC descriptor discovery
  3. Enable Notifications
  4. Central MTU Updated TX: 247 RX: 247 bytes
  5. PHY updated: TX PHY 2M, RX PHY 2M
  6. Connection Params:interval 7.50 ms, latency 1, timeout 100 ms
  7. start stream data over notifications at 120hz
  8. wait 3 seconds
  9. Hit reset on peripheral 
  10. Central Hangs indefinitely with no supervision timeout

    It's started intermittently working on my end now too 

    any chance you could run it few more time to make sure

    Hi,

    I tested some more times now, but still don't see the issue with missing disconnected event (I do hovere sometimes see a fault in BT RX WQ thread after connection which I also saw yesterday.

    With addr2line I see it is in Bluetooth_Central/src/bluetooth.c:674, your notify_func().

    This is a separate issue from what you are describing though, but maybe it could be related to some of the many log related warnings you get when building the project, so I suggest cleaning up the logging and making sure the project builds without warnings.

    Hi Einar,

    I have removed all the build errors and pushed to the git repo.

    I now don't even get it to intermittently work!

    I have also never seen that fault occurs after connection which is strange

    I do get these 3 problems:
