It seems that TI-RTOS have memory Problems after a BLE Stack update to latest version 2.0.

Whenever funktion GATT_bm_alloc located in "ICallBLEAPI.c" is called an error returned.

Which stack must be increased to solve my memory problems?

Many thanks for any support

Hi,

GATT_bm_alloc allocates memory from the ICall heap. Please see Section "3.11.5 Dynamic Memory Allocation" in the SW Developer's Guide (SWRU393). Specifically, read the details about the HEAPMGR_SIZE.

Also, if you are using GATT_bm_alloc, make sure your use of GATT_bm_free is proper. See the example usage in gattServApp_SendNotiInd within gattservapp_util.c

Best wishes

Your comment helped me to find the problem.
Real cause was a wrong integrated bleUserConfig file.
Because of this the stackpointer was not set.
Thanks for your help.
