CC2652R: How to find handle of the simpleprofile characteristic 5 value

Part Number:CC2652R

Hi All,

I'm trying to write in characteristic 5 in simple peripheral from simple central, I have changed the permission to write, now I need to find handle of the simpleprofile characteristic 5 value  , how can I do that? in the example handle of the simpleprofile characteristic 1 value is found in pMsg->msg.readByTypeRsp.pDataList[3],  pMsg->msg.readByTypeRsp.pDataList[4] but I don't understand how this is found.

Thanks in advance
