Hi,

I still can hit below issue sometimes on SDK-3.7.0-7.

Basically, the device is useless after this issue happened.

If there is still no fix available for now, how can I detect this issue?

I'd like to make the device reboot if this issue happened.

Any callback or notification I can know this issue happened?

Below is the message for reference:

Add rash

AFAICT, the GKI_exception() issue is too critical because the device no longer work.

You need to provide a method for application developers to detect the exception.

Hi,

Can someone help on this issue?

It happens randomly in random devices.

The problem is when this happened, the device does not work anymore unless reboot.

I have no way to detect if this happen, in additional, the watchdog does not

work because the device is still alive but only BT no longer work.

I have a batch of devices going to release next Month, I'm worried about this issue.

BTW, do you consider to make the output more verbose?

I think below messages does not help too much to analyze the root cause.

I start getting some customers report about such issue.

This problem is annoy for us because the device becomes a dead board.

I tried increasing buffer size but it seems does not help, and I cannot debug it at all because it's binary released code.

Also it seems easier to reproduce it if enable STDIO output.

I'm wondering if the BLE library has STDIO debug print which causes problems? (well, just a guess.)

It's easy to get GKI_exception 65524 getbuf: out of buffers if the code to handle scan_result callback got block

for a small delay. This can happen if you have another thread doing tcp connect to server.

I have reported this issue for several weeks can someone help?

BTW, I'm wondering why running out of buffers is so fatal which make the BT part complete dead.

The buffer is likely to be available soon even, isn't it?

Any update?

And do you have any plan/bug fix for next sdk-3.x update?

I hit this issue again.

From the timestamp, you can see it happens immediately after GKI_create_task.

Cypress team,

Since you don't response on this issue.

Can you at least tell me how to detect if the exception happens so we have a chance to reboot the device as workaround?

Hi axel,

Maybe last chance are test string message in wiced_uart_transmit_bytes->platform_uart_send_message...

If debug uart and strstr "GKI_exception 65527 getbuf: Size is too big"...reboot.

That won't work because we have NOSTDIO in release build.
