Hello Cypress team,

My firmware is based on WiCED SDK-3.5.2 upon BCM43340. My question is how to disconnect a BLE link when my role is a peripheral (link_role equals 1)? I've tried wiced_bt_gatt_disconnect(uint16_t conn_id), but this API only works when my role is a central (link_role equals 0). If I call wiced_bt_gatt_disconnect in the peripheral case, the WiCED BT driver will get stuck and keep dumping run out of buffer messages. The error messages are shown below. Can anybody tell me how to correctly disconnect the link?

...... (continuously output the above error message)

Kindly update to the latest version of the WICED SDK. The wiced_bt_gatt_disconnect() API should work fine.

Look at the struct wiced_bt_cfg_buf_pool_t you used for wiced_bt_stack_init call.

As far as I know with 3.5.2 you don't have any hint about their real-time usage.

However you can blindly adjust the buffer config and hope for the best.

I'll recommend you to migrate to latest SDK and get prepared for future migrations.

You will not like to rely on official patches for non-latest SDK...
