Forum Post: Can NOT Send Notification after upgrade from 1.0 to 1.21

Hello,

The mechanism of sending the notification of Characteristic-4(char4) of the simpleBLE keyfob has been changed a lot from (stack version) 1.0 to 1.21.

In v1.0, I modified the content of char4 to become a 10-element uint8 array (uint8 char4[10]).

In the SimpleProfile_SetParameter() of "simpleGATTprofile.c", I modified the  function to send out my byte stream using the  GATT_Notification( simpleProfileConnHandle, &notify, FALSE ) function. This is a simple way to to send things out.

In v1.21, it passed the task to GATTServApp_ProcessCharCfg(). I have tried to modify my program code, but not successful. There is no source code for ...ProcessCharCfg() and not much mention about that function in the document.

My question is, how to and what is the correct way to send out notification in v1.21? Does it matter how I set the value of the handle of notification?  If you had tried this before, could you share your experience?

Thank you!
