Hello,
I'm trying to get the Bluetooth working on a my board but somehow I very often get the error:
GKI_exception 65524 getbuf: out of buffers
GKI_exception(): Task State Table
My pools are the following:
64 * 4
360 * 100
360 * 100
600 * 1
I tried to see what was happening by launching a periodic task that prints the state of the buffers using the GKI_* routines and it turns out that sometimes the buffers get filled in very quickly, in less than a second I get the two 360 buffers full. Why that ?
I can't really find a pattern for the behaviour, it happens when I launch a scan or when I try to discover the services of a connected device.
What are the recommendations for the pools sizes ? I don't find any documentation.
Thank you.
Arthur.

Up. I now very often get this issue when trying to connect to a device, I tried to set 1000 buffers of 360 but it doesn't change anything, they get full.

Hi,
Pools defined by you seems to be fine for a typical bluetooth application - BUT I'd recommend to increase the number of buffers in the 4th pool bit more.
This is what you could try with :
64 * 4
360 * 100
360 * 100
600 * 10
Please share if above works or not - If it does not please share more details on following:
- Platform/Board being used
- SDK version in use
- What kind of application which you've been trying ? Is it a dual-mode(classic) or Low-energy bluetooth application ?
- Any sequence of step or any necessary condition to generate these GKI errors ?
Thanks,
