CC2564CSTBTBLESW: BTHID_ERROR_INSUFFICIENT_RESOURCES error

Part Number:CC2564CSTBTBLESW

Hi,

I am running HID demo on my device that works as a peripheral. For Every message it tries to send ( by HID_Get_Report_Response or HID_DATA_WRITE or any others) to the host, we always get the BTHID_ERROR_INSUFFICIENT_RESOURCES (-1004) error as the return value. What does this error mean? How does it occurs and how to get rid of it? Thanks!
