KW36 : Directed advertising query

skalyan2 — Sun, 22 Sep 2019 13:14:28 GMT

Hi,

Peripheral device : KW36, central device : Samsung note 9

I tried to do directed advertising by filling peerAddress parameter of gapAdvertisingParameters_t structure with central device(Samsung note 9 ) address, but directed advertising seems to be not happening with KW36.

Can you please check and update ( I used hid_device example), many thanks in advance.

Regards

Hello,

Is this happening with different devices ? or is this happening only with the Samsung note 9 ?

Hi Estephania,

It is with all phones, i have not enabled privacy, is this because of this ?

Have you tried reproducing from your end ?

If not reproducing, can you please disable privacy and try reproducing ?

Hi estephania_martinez‌,

I changed the advertisingType as gAdvDirectedHighDutyCycle_c and filled directedAddress with peer device address and have called Gap_SetAdvertisingParameters, i have not done anything else (i didnt enable privacy).

Hello,

Could you please try setting the following advertisement parameters?

gapAdvertisingParameters_t gAdvParams =
 {
    /* minInterval */         gGapAdvertisingIntervalDefault_c, 
    /* maxInterval */         gGapAdvertisingIntervalDefault_c, 
    /* advertisingType */     gAdvDirectedHighDutyCycle_c,  //gAdvDirectedLowDutyCycle_c
    /* addressType */         gBleAddrTypeRandom_c,
    /* directedAddressType */ gBleAddrTypePublic_c, 
    /* directedAddress */     {0x00, 0x60, 0x37, 0xB0, 0x8A, 0x1B}, //Address for ADV
    /* channelMap */          (gapAdvertisingChannelMapFlags_t) (gGapAdvertisingChannelMapDefault_c), 
    /* filterPolicy */        gProcessAll_c 
};‍‍‍‍‍‍‍‍‍‍‍
‍‍‍‍‍‍‍‍‍‍‍‍

/*! Minimum advertising interval (20 ms) */
#define gGapAdvertisingIntervalRangeMinimum_c 0x0100 //0x0020 @DAdv
/*! Default advertising interval (1.28 s) */
#define gGapAdvertisingIntervalDefault_c 0x0800
/*! Maximum advertising interval (10.24 s) */
#define gGapAdvertisingIntervalRangeMaximum_c 0x0800 //0x4000 @DAdv
‍‍‍‍‍‍

/* Setup Advertising and scanning data */
Gap_SetAdvertisingData(NULL,NULL);//(&gAppAdvertisingData,&gAppScanRspData); //@DAdv

‍‍‍‍

Regards

嗨estephania_ mart
我已经完全按照您给我的参数设置进行了配置。我使用了SDK的“蓝牙” W_ uart_ FreeRTOS“，我专门查看了手机的蓝牙地址为“ e0：cc：f8：a2：5a ：3a”。然后，我按如下所示配置代码，但是我的手机找到定向广播设备。

gapAdvertisingParameters_t gAdvParams =
{
/ * * minInterval / gGapAdvertisingIntervalDefault_c，
/ * maxInterval * / gGapAdvertisingIntervalDefault_c，
/ * advertisingType * / gAdvDirectedHighDutyCycle_c，// gAdvDirectedLowDutyCycle_c
/ *地址类型* / gBleAddrTypeRandom_c，
/ * directedAddressType * / gBleAddrTypePublic_c，
/ * directedAddress * / {取0xE0，0xCC，0xF8、0xA2、0x5A，0x3A}，// ADV的地址
/ * channelMap * /（gapAdvertisingChannelMapFlags_t）（gGapAdvertisingChannelMapDefault_c），
/ * filterPolicy * / gProcessAll_c
};

您能花点时间为我解决这个问题吗？非常感谢你。

Hi estephania_ mart
I have configured it completely according to the parameter settings you gave me. I used the SDK's "Bluetooth"_ W_ uart_ FreeRTOS ", I specially looked at the Bluetooth address of my mobile phone. Then I configure the code as shown below, but my mobile phone can't find the directional broadcast device.Could you take time to look at this problem for me? Thank you very much.

My mobile device is Xiaomi 10, Bluetooth address is：e0:cc:f8:a2:5a:3a

gapAdvertisingParameters_t gAdvParams =
{
/* minInterval */ gGapAdvertisingIntervalDefault_c,
/* maxInterval */ gGapAdvertisingIntervalDefault_c,
/* advertisingType */ gAdvDirectedHighDutyCycle_c, //gAdvDirectedLowDutyCycle_c
/* addressType */ gBleAddrTypeRandom_c,
/* directedAddressType */ gBleAddrTypePublic_c,
/* directedAddress */ {0xE0, 0xCC, 0xF8, 0xA2, 0x5A, 0x3A}, //Address for ADV
/* channelMap */ (gapAdvertisingChannelMapFlags_t) (gGapAdvertisingChannelMapDefault_c),
/* filterPolicy */ gProcessAll_c
};

I used two development boards to do experiments, but I didn't get the Bluetooth address of the directional broadcast device.
