Hello,

I am using multi_role example code for launchpad and I am connecting one peripheral directly using GAP commands,

here I want to receive notification from peripheral to multirole client, here my peripheral sends notification from Charecteristic 4,

I am trying to enabling CCCD from client side,

but it is not getting enabled, here I am sharing code snippets.

        else if (discInfo[connIndex].discState == BLE_DISC_STATE_CHAR)
        {

            // Characteristic descriptors found
            if (pMsg->method == ATT_FIND_INFO_RSP &&
                    pMsg->msg.findInfoRsp.numInfo > 0)
            {
              uint8_t i;
              // For each handle/uuid pair
              for (i = 0; i < pMsg->msg.findInfoRsp.numInfo; i++)
              {
                if(pMsg->msg.findInfoRsp.format == ATT_HANDLE_BT_UUID_TYPE)
                {
                  // Look for CCCD
                  if (ATT_BT_PAIR_UUID(pMsg->msg.findInfoRsp.pInfo, i) ==
                          GATT_CLIENT_CHAR_CFG_UUID)
                  {
                    // CCCD found
                    if (noCharCCCDHdl < MAX_CCCD_HANDLES){
                        charCCCDHdl[noCharCCCDHdl] = ATT_BT_PAIR_HANDLE(pMsg->msg.findInfoRsp.pInfo, i);
                        noCharCCCDHdl++;
                    }
                  }
                }
              }
            }

This code is inside multi_role_processGATTDiscEvent

static uint8_t multi_role_processGATTMsg(gattMsgEvent_t *pMsg)
{
  // See if GATT server was unable to transmit an ATT response
  if (pMsg->hdr.status == blePending)
  {
    // No HCI buffer was available. Let's try to retransmit the response
    // on the next connection event.
    if (HCI_EXT_ConnEventNoticeCmd(pMsg->connHandle, selfEntity,
                                   MR_CONN_EVT_END_EVT) == SUCCESS)
    {
              System_printf("Inside conn event notice command\n");
              System_flush();
      // First free any pending response
      multi_role_freeAttRsp(FAILURE);

      // Hold on to the response message for retransmission
      pAttRsp = pMsg;

      // Don't free the response message yet
      return (FALSE);
    }
  }
  else if (pMsg->method == ATT_FLOW_CTRL_VIOLATED_EVENT)
  {
    // ATT request-response or indication-confirmation flow control is
    // violated. All subsequent ATT requests or indications will be dropped.
    // The app is informed in case it wants to drop the connection.

    // Display the opcode of the message that caused the violation.
//    Display_print1(dispHandle, 0, 0, "FC Violated: %d", pMsg->msg.flowCtrlEvt.opcode);
  }
  else if (pMsg->method == ATT_MTU_UPDATED_EVENT)
  {
    // MTU size updated
    Display_print1(dispHandle, 0, 0, "MTU Size: %d", pMsg->msg.mtuEvt.MTU);
  }

  //messages from GATT server
  if (linkDB_NumActive() > 0)
  {
//      System_printf("Inside linkDB_NumActive>0\n");
//      System_flush();
    //find index from connection handle
    connIndex = multi_role_mapConnHandleToIndex(pMsg->connHandle);

    if ((pMsg->method == ATT_READ_RSP) ||
            (pMsg->method == ATT_HANDLE_VALUE_NOTI) ||
            ((pMsg->method == ATT_ERROR_RSP) &&
                    (pMsg->msg.errorRsp.reqOpcode == ATT_READ_REQ)))
    {
      if (pMsg->method == ATT_ERROR_RSP)
      {
//        Display_print1(dispHandle, 0, 0, "Read Error %d", pMsg->msg.errorRsp.errCode);
      }
      else
      {
        // After a successful read, display the read value
//        Display_print1(dispHandle, 0, 0, "Read rsp: %d", pMsg->msg.readRsp.pValue[0]);
        uint8_t *notificationdata = pMsg->msg.handleValueNoti.pValue;
      }

    }
    else if ((pMsg->method == ATT_WRITE_RSP)  ||
             ((pMsg->method == ATT_ERROR_RSP) &&
              (pMsg->msg.errorRsp.reqOpcode == ATT_WRITE_REQ)))
    {
      if (pMsg->method == ATT_ERROR_RSP == ATT_ERROR_RSP)
      {
//        Display_print1(dispHandle, 0, 0, "Write Error %d", pMsg->msg.errorRsp.errCode);
      }
      else
      {
        // After a succesful write, display the value that was written and
        // increment value
//        Display_print1(dispHandle, 0, 0, "Write sent: %d", charVal++);
      }
    }
    else if (discInfo[connIndex].discState != BLE_DISC_STATE_IDLE)
    {
      multi_role_processGATTDiscEvent(pMsg);
    }
  } // else - in case a GATT message came after a connection has dropped, ignore it.

  // Free message payload. Needed only for ATT Protocol messages
  GATT_bm_free(&pMsg->msg, pMsg->method);

  // It's safe to free the incoming message
  return (TRUE);
}

This is multi_role_processGATTMsg function

static void multi_role_EnableNotification( uint16 connHandle, uint16 attrHandle )
{
    attWriteReq_t req;
//    System_printf("Inside enable notification\n");
//    System_flush();
    req.pValue = GATT_bm_alloc( connHandle, ATT_WRITE_REQ, 2, NULL );
    if ( req.pValue != NULL )
    {
      uint8 notificationsOn[] = {0x01, 0x00};
  //    attAttribute_t
      req.handle = attrHandle;

      req.len = 2;
      memcpy(req.pValue, notificationsOn, 2);

      req.sig = FALSE;
      req.cmd = TRUE;

      if ( GATT_WriteNoRsp( connHandle, &req ) != SUCCESS )
      {
        GATT_bm_free( (gattMsg_t *)&req, ATT_WRITE_REQ );
      }

    }
}

This is enable notification function

  Util_constructClock(&startNotiEnableClock, multi_role_startNotiHandler,
                        DEFAULT_NOTI_ENABLE_DELAY, 0, false, SBC_START_NOTIFICATION);

    if (currentCharCCCDHdlIndex < noCharCCCDHdl)
    {
      multi_role_EnableNotification( connHandle, charCCCDHdl[currentCharCCCDHdlIndex ] );
      currentCharCCCDHdlIndex ++;

       //Enable notification on peripheral(after a few seconds delay, let it finish connection/discovery process)
       {
         Util_startClock(&startNotiEnableClock);
       }
    }

This is timer for some delay for connection establishment.

here in multi_role_processGATTDiscEvent while debugging i found that It's not going into loop where I find CCCD.

Please provide some guidance so I can resolve this issue as soon as possible.

Part Number:TPS546D24

MSEL,MSEL2,VSEL, register values not described in datasheet.

It looks very similar architecture with 548d22, 549d22 .

different things are 546d24 uses voltage divider bp1v5 .

But, others and most of previous ti power ic uses BP2V5.

Could you give a information on that? draft datasheet is also very helpful to me.
I've finished single mode and dual mode 543c20 design.

thanks.

Part Number:IWR6843

So i recently bought a mmwaveicboost and IWR6843 antenna, but im having some trouble running the demo from the mmWave Demo Visualizer. I can flash the board using UniFlash, but when i change the SOP2 to open, restart the sensor, connect the demo visualizer with the correct COM ports, the demo only shows "waiting for data ..." even after i click "Send config to mmwave device". I've tried the "68xx - People counting demo" from the TI Resource explorer and again the same results (can flash the board but no communication after), using this demo the message is "Warning: Unsuccessful read: The specified amount of data was not returned within the Timeout period..".

Part Number:ADS1284

Hi team,

Customer wants to use ADS1284 in their project, but I find there is no detailed price and sample in web. Could you help check the current status and schedule of ADS1284? 

Thanks and Best Regards,

Will

Good afternoon, TI.

Tell me please what will happen in the next situation, maybe you can tell me how best to do it.
I am using TMS32028379D.
I have a synchronous measurement of ADC 1 (A) and ADC 2 (B), while each ADC has its own DMA channel (1 ( high priority) and 2) and configured the ripping vector ADCINTA1, ADCINTB1 for each SOC of the ADC.
I also use the DMA channel 4,5,6 (configured).

In the case when I am processing the DMA 4 channel, the ADCINTA1 and ADCINTB1 interrupt is triggered at the same time, the data is unloaded from the DMA 1 priority channel, after the DMA1 download is completed, the DMA2 will go to the processing, or return to channel 4, 5.6 and only after Processing them to channel 2? Channel 2 is configured to interrupt ADCINTB1 which is triggered simultaneously with ADCINTA1.

My task is to make it so that when the ADCINTA1 and ADCINTB1 snagging is triggered, the information from ADCs A and B is unloaded into RAM with priority No. 1 by means of DMA CH1 and DMA CH2. Perhaps you can tell me how to set up DMA 1 so that it processes ADC A and ADC B in turn. Or how can I set high Prioryty on CH1 and CH2.

Part Number:TPS2000C

The TPS2000C datasheet details 'reverse current blocking when disabled' as a feature in the overview section. Can this device--or any other similar 2A-limited USB switches--be used to allow reverse current with minimal voltage drop? I'm looking for a single, inexpensive device to provide current limiting from IN to OUT while allowing current (with or without limit) from OUT to IN.

Part Number:CSD17573Q5B

Tool/software:TINA-TI or Spice Models

I have pulled the most recent version of the CSD17573Q5B PSpice Model from the TI web page.  I am running Orcad 17.2-2016-S048.  When I attempt to simulate with the model, PSpice gives me a netlisting error.  Relevant output from PSpice follows; it appears that an undeclared "NMOSW" model is used inside the CSD17573Q5B's encrypted model.

Hi, I use internal sensor of TM4C1294NCPDT. When i read positive degrees it works fine but when i want to read negative degrees it always shows zero degree. What is my mistake? 

Part Number:TMS570LC4357

Tool/software: TI C/C++ Compiler

Hello,

I want to run a smal program on the chip. I faced two main problems:

- the first is that if I do the array initialization in this way : 

xmss_params params;
    // TODO test more different OIDs
    uint32_t oid = 0x00000001;

    /* For WOTS it doesn't matter if we use XMSS or XMSSMT. */
    xmss_parse_oid(&params, oid);
 
    unsigned char seed[params.n];

Th program enter in a infinite loop.

To solve that i defined manually the size of the arrays. e.g. 

unsigned char seed[32];
Which is not practical. Is it another solution for that?

- The second problem is: when I add code lines to the main function, the program stopped in the first line, and the debugger indicates these code line data entry:

resetEntry
        b   resetEntry
undefEntry
        b   undefEntry
svcEntry
        b   svcEntry
prefetchEntry
        b   prefetchEntry
dataEntry
        b   dataEntry
        b   phantomInterrupt
        ldr pc,[pc,#-0x1b0]
        ldr pc,[pc,#-0x1b0]

When I delete the last code lines and minimize the size of main function, the error disappears.

Bests,

Rachel.

Part Number:UCC2818

Hello,

I designed a PFC converter which has the following features :

Vinac = 85V~130V (Typical input voltage is 115Vac)

Frequency = 400Hz ~ 800Hz. ( go from 400Hz to 800Hzn, avionic power supply)

Vout = 260V/ Poutmax = 150W.

I m using the controller UCC2818.

My issue is about the current harmonic distortion. I want to know if there is trick that exists to improve the distortion during the current crossing of zero.

I used your mathcad file and your note application to choose peripheral component (voltage and current loops).

bellow the current waveform @Pout=400W, Vin=85V, Vout=260V.

The waveform is correct except when the current is crossing zero.

I tried to change current loop component, it allows to improve the current waveform and harmonic distortion but it is not enough to meet the specifications.

Thank you for your help.

Hi team,

For the following description of USB OTG feature of BQ25710. Is the 10ms claimed as marked in the capture below (between EN and Vbus ramp up) can be reduced by external methods? Or it is a defaulted fixed setting by IC?

Thanks.

Hi Team,

i am supporting TPS546D24. Using thermal simulation to find out its performance in high temp. is quite significant. After created the simulation, i found the case just stoped in "Queued" state and did not proceed for more than hrs. Could you please check the reason and E-mail me? I will send the webench link to you. Thanks
