CC2642R: Send notification to central through CHAR4 is not working in simple peripheral code

Hey Mohan,

Which SDK are you using? I've assigned a colleague to help you with your post.

Hi Mohan,

Can you provide the debug log when stuck in  GATT_Notification?

Meanwhile, I think you can try char4 updating  under this guidance Custom Profile (ti.com)

Best regards! 

I am using this SDK (simplelink_cc13x2_26x2_sdk_5_20_00_52)

HI Simon,

SDK i am using is : simplelink_cc13x2_26x2_sdk_5_20_00_52.run

It stucking means not even a debug print is coming after that .

SimpleProfile_SetParameter -> GATTServApp_ProcessCharCfg-> gattServApp_SendNotiInd -> GATT_Notification(stucking here) ....

before the  GATT_Notification() function i added one print .... that print is displaying (Printt -> Ntfy Handle 0x2b | cccValue 1)

after GATT_Notification() function also i has one more print that is not even printing.....

can you please tell some idea about this????

Here i will posted the code flow details....

step 1: Simplepheripheral_SetParameter(SIMPLE_PHERIPHERAL_CHAR4, in_u8len, in_u8buffer);       (WORKING)

step 2: In Simplepheripheral_SetParameter function -> inside SIMPLE_PHERIPHERAL_CHAR4 switch case below function is calling  (WORKING)

 GATTServApp_ProcessCharCfg( simpleProfileChar4Config, SimplepheripheralNtfyChar_profile, FALSE,
SimplepheripheralProfileAttrTbl, GATT_NUM_ATTRS( SimplepheripheralProfileAttrTbl ),
INVALID_TASK_ID, Simplepheripheral_ReadAttrCB ); 

step 3: In  GATTServApp_ProcessCharCfg function -> inside a ........... 

pAttr = GATTServApp_FindAttr( attrTbl, numAttrs, pValue );
if ( pAttr != NULL )
{
if ( pItem->value & GATT_CLIENT_CFG_NOTIFY )
{

status |= gattServApp_SendNotiInd( pItem->connHandle, GATT_CLIENT_CFG_NOTIFY,
authenticated, pAttr, taskId, pfnReadAttrCB );(WORKING)

}

below function is calling ,,,,,,,,,,,,,

status |= gattServApp_SendNotiInd( pItem->connHandle, GATT_CLIENT_CFG_NOTIFY,
authenticated, pAttr, taskId, pfnReadAttrCB );

step 4: Inside a function -> GATT_Notification() is stucked    (NOT WORKING)

static bStatus_t gattServApp_SendNotiInd( uint16 connHandle, uint8 cccValue,
uint8 authenticated, gattAttribute_t *pAttr,
uint8 taskId, pfnGATTReadAttrCB_t pfnReadAttrCB )
{
attHandleValueNoti_t noti;
uint16 len;
bStatus_t status;

// If the attribute value is longer than (ATT_MTU - 3) octets, then
// only the first (ATT_MTU - 3) octets of this attributes value can
// be sent in a notification.
noti.pValue = (uint8 *)GATT_bm_alloc( connHandle, ATT_HANDLE_VALUE_NOTI,
GATT_MAX_MTU, &len );
if ( noti.pValue != NULL )
{
status = (*pfnReadAttrCB)( connHandle, pAttr, noti.pValue, &noti.len,
0, len, GATT_LOCAL_READ );
if ( status == SUCCESS )
{
noti.handle = pAttr->handle;

if ( cccValue & GATT_CLIENT_CFG_NOTIFY )
{
 printf(LOGD, " Ntfy Handle 0x%x | cccValue %d ", pAttr->handle, cccValue); //This line is printing

*status = GATT_Notification( connHandle, &noti, authenticated );   /////////////////////////////Here it is stucked----------------------------))))))))))))))))))))))*

 printf(LOGD, " Status ///// : %d", status); //This line is Not printing
}
else // GATT_CLIENT_CFG_INDICATE
{
status = GATT_Indication( connHandle, (attHandleValueInd_t *)&noti,
authenticated, taskId );
}
}

if ( status != SUCCESS )
{
GATT_bm_free( (gattMsg_t *)&noti, ATT_HANDLE_VALUE_NOTI );
}
}
else
{
status = bleNoResources;
}

 //printf(LOGD, " End of gattServApp_SendNotiInd"); 

return ( status );
}
