Parameters connHandle – connection handle (0xFFFF for all connections).
charCfgTbl – client characteristic configuration table where this characteristic is
bStatus_t GATTServApp_ProcessCharCfg( gattCharCfg_t *charCfgTbl, uint8 *pValue,uint8
authenticated, gattAttribute_t *attrTbl, uint16 numAttrs, uint8 taskId,
pfnGATTReadAttrCB_t pfnReadAttrCB )
Process Client Characteristic Configuration change.
Parameters charCfgTbl – profile characteristic configuration table
pValue – pointer to attribute value.
authenticated – whether an authenticated link is required
attrTbl – whether attribute table.
numAttrs – number of attributes in attribute table.
tasked – task to be notified of confirmation.
pfnReadAttrCB – read callback function pointer.
