Hi,

I commented line no. 3318 of subsys/bluetooth/host/hci_core.c i.e. // BT_ASSERT(buf);

And after that everything is working perfectly normal.

Thanks !!

Hi Carles,

I tried it with samples/boards/nrf52/mesh/onoff-app ....Here too, I faced kernel OOPS.

But in that case, occurrence frequency was very low.

I'm facing all these issues after 1.12.0-rc2 update. Previously, everything was working perfectly.

Let me again thoroughly go through with my code. 🤔

Thank You !!

Hi Vikrant,

 

Can you please try to reproduce this with standard samples present in the Zephyr tree?

 

Thanks,

This is starting to look more and more like a memory corruption or kernel issue at this point.

I cannot reproduce this easily by running our standard Bluetooth samples, so I am a bit at a loss here. I will try to run a mesh sample to see if it fails in the same way.

Hi Vikrant,

 

Thanks for looking into this. It seems like we do not get a buffer back from the command tx queue: https://github.com/zephyrproject-rtos/zephyr/blob/master/subsys/bluetooth/host/hci_core.c#L3318

 

I have copied Luiz and Johan from Intel in case they know what the cause might be.

 

Regards,

 

Carles
