CCS/CC2650: My bluetooth advertisement data can't update

Part Number: CC2650

Tool/software: Code Composer Studio

I'm working with CC2650 LaunchPad and CC2650 MODA , at first I can use

GAPRole_SetParameter(GAPROLE_ADVERT_DATA, sizeof(broadcastData), broadcastData);

to change the advertisement data, it's work fine at first , but somehow it didn't work , I have reinstalled the ccs and simplelink SDK,

and let my project to the last worked version , but it still can't work.

I tried on the other computer it's work fine but the other computer had become the same situation, it bother me so much.
this is what I init my bluetooth code:

static void SimpleBLEBroadcaster_init(void)
{
  ICall_registerApp(&selfEntity, &sem);

  // Hard code the DB Address till CC2650 board gets its own IEEE address
  // 強制設定 MacAddress
//  uint8 bdAddress[B_ADDR_LEN] = { 0x33, 0x33, 0x33, 0x33, 0x33, 0x33 };
//  HCI_EXT_SetBDADDRCmd(bdAddress);

  appMsgQueue = Util_constructQueue(&appMsg);

  // Setup the GAP Broadcaster Role Profile
  {
    uint8_t initial_advertising_enable = TRUE;
    uint16_t gapRole_AdvertOffTime = 0;
    uint8_t advType = GAP_ADTYPE_ADV_NONCONN_IND; // use non-connectable adv

    GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t), &initial_advertising_enable);
    GAPRole_SetParameter(GAPROLE_ADVERT_OFF_TIME, sizeof(uint16_t), &gapRole_AdvertOffTime);
//    GAPRole_SetParameter(GAPROLE_SCAN_RSP_DATA, sizeof (scanRspData), scanRspData);
    GAPRole_SetParameter(GAPROLE_ADVERT_DATA, sizeof(broadcastData), broadcastData);
    GAPRole_SetParameter(GAPROLE_ADV_EVENT_TYPE, sizeof(uint8_t), &advType);
  }

  // Set advertising interval
  {
    uint16_t advInt = DEFAULT_ADVERTISING_INTERVAL;

    GAP_SetParamValue(TGAP_LIM_DISC_ADV_INT_MIN, advInt);
    GAP_SetParamValue(TGAP_LIM_DISC_ADV_INT_MAX, advInt);
    GAP_SetParamValue(TGAP_GEN_DISC_ADV_INT_MIN, advInt);
    GAP_SetParamValue(TGAP_GEN_DISC_ADV_INT_MAX, advInt);
  }

  // Start the Device
  VOID GAPRole_StartDevice(&simpleBLEBroadcaster_BroadcasterCBs);
}

and this is the code I update the data:

updateValue(); //update broadcast Data

GAPRole_SetParameter(GAPROLE_ADVERT_DATA, sizeof(broadcastData), broadcastData);

and broadcastData :

static uint8_t broadcastData[] =
{
  // length of device name
  (deviceNameLength + 1),   // length of this data
  GAP_ADTYPE_LOCAL_NAME_COMPLETE,
  0x53,	// S
  0x54,	// T

  // Flags; this sets the device to use limited discoverable
  // mode (advertises for 30 seconds at a time) instead of general
  // discoverable mode (advertises indefinitely)
  0x02,   // length of this data
  GAP_ADTYPE_FLAGS,
  GAP_ADTYPE_FLAGS_BREDR_NOT_SUPPORTED,

  0x16, // length of this data including the data type byte
  GAP_ADTYPE_MANUFACTURER_SPECIFIC, // manufacturer specific adv data type
  0x0D, // Company ID - Fixed
  0x00, // Company ID - Fixed
  0x02, // Data Type - Fixed
  0x11, // Data Length - Fixed
  0x00, // Major
  0x01, // Major
  0x00, // Minor
  0x01, // Minor
  0xc5,  // Power - The 2's complement of the calibrated Tx Power

  0xAA, // 6 accel
  0xAA,
  0xAA,
  0xAA,
  0xAA,
  0xAA,

  0xBB, // 6 gyro
  0xBB,
  0xBB,
  0xBB,
  0xBB,
  0xBB

};

My English is not very good.

and this is my first post , if something doesn't right,

Thanks for your consideration for any inconvenience caused.

I have resolved this by replace the code:

GAPRole_SetParameter(GAPROLE_ADVERT_DATA, sizeof(broadcastData), broadcastData);

to this code:

GAP_UpdateAdvertisingData(selfEntity,TRUE,sizeof(broadcastData),broadcastData);

and it's work fine.

but still can't get why

GAPRole_SetParameter()

can't work.

Hi Laurence,

Glad you found a solution.

The advertisement data can only be updated when advertising is not enabled.
