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

Hi,

I built the code you shared from Github, but can you explain in detail how it should be used to reproduce the issue (I just naively followed intrusctions by pressing button 1 and button 1 again on the central, but a connection is never initiated (though the peripheral is found).

PS: I see many warnings when building both the central and peripheral code. At first glacne non seems likely relevant for this issue, but I would advice that you make the code build free of warnings to avoid that a stream of irrelevant warning possibly mask an important one.

Hi einar,

yes sorry for not giving instructions.

• press button one to scan
• type though serial monitor  bt connect <number on scan list>
• Type through serial monitor bt sensors  <peripheral name> 
• Type through serial monitor bt stream <peripheral name> on

to see other available commands type bt

Hi,

I see. When I test like you described, and reset the peripheral, I get the disconnected callback as expected

This is using nRF Connect sdk 2.9 without modifications, and your projects from Github without modifications (this means that I stil have CONFIG_LOG_MODE_MINIMAL=n and CONFIG_BT_ATT_LOG_LEVEL_DBG=n).

Do I need to do anythign else to reproduce?

Hi Einar,

Thanks for running the code.

I’m now very confused, with the same code running standard nrf connect sdk 2.9 on an nrf5340dk I do not get the supervision timeout. How many times have you repeated the test? 

do you have any suggestions as to what else the difference between our setups could be?

Hi,

I only tested once before, but tested a few times more now wihtout seeing any issue. Does it only happen sometimes when you test? Do you have any changes in the SDK files that could explain differences we are seeing (you can check with "west status")?
