Hi,

I am using Murata Type 1Dx module, which uses Broadcom BCM4343W chipset.

I am  trying to bring-up the Bluetooth module & using WICED SDK 3.5.2

My host MCU platform is ARM Cortex M4. I am using WICED-SDK-3.5.2\apps\snip\bluetooth\ble_hello_sensor application.

I could see read/write operations happening through UART port.

On Console I see below messages

00000000 GKI_create_task func=0xfa1d  id=1  name=BTU  stack=0x0  stackSize=6144

00000000 GKI_create_task func=0x10e91  id=0  name=HCISU  stack=0x0  stackSize=4096

00096110 GKI_exception(): Task State Table

00096110 GKI_exception 65524 getbuf: out of buffers

00100110 GKI_exception(): Task State Table

00100110 GKI_exception 65524 getbuf: out of buffers

00124110 GKI_exception 65524 getbuf: out of buffers

Program control never reaches in  bt/ble link management callback function. Whereas the "Out of buffers" message keeps on coming. I also tried increasing  buffer count in wiced_bt_cfg_buf_pools (defined in file WICED-SDK-3.5.2\apps\snip\bluetooth\ble_hello_sensor\wiced_bt_cfg.c). But this did not help.

How can I solve this "getbuf: out of buffers" issue?

It will be very helpful if someone can provide pointers on this.

Thanks & Regards,

Pratik.

Depends on the profiles enabled.

But in general currently if this is BLE only then need at least 96KB of SRAM for reliable operation
