"Manufacturer Specific Data" does not reflect values

[takashina hiroki]

SDK: 15.3.0
SoftDevice: S132
Device: EYSHJNZWZ (nRF52832)

I want to use "Manufacturer Specific Data".
I created a sample program, but 8 bytes from the beginning are not set to the value I set.
Please tell me what is the cause.

static	ble_uuid_t	m_adv_uuids[] =
{
	{
		0x1234,
		BLE_UUID_TYPE_VENDOR_BEGI
	}
};

BLE_ADVERTISING_DEF(m_advertising);
ble_advertising_init_t		g_advinit;
ble_advdata_manuf_data_t manufacturer_specific_data;
uint8_t manuf_specific_data[16];

memset(&g_advinit, 0, sizeof(g_advinit));	
memset(&manufacturer_specific_data, 0, sizeof(manufacturer_specific_data));	

g_advinit.advdata.name_type				= BLE_ADVDATA_FULL_NAME;
g_advinit.advdata.include_appearance	= false;
g_advinit.advdata.flags					= BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

for(i=0; i<16; i++) {
	manuf_specific_data[i] = (i + 1);
}
manufacturer_specific_data.company_identifier	= 0xFFFF;
manufacturer_specific_data.data.size			= ( sizeof(manuf_specific_data) / sizeof(manuf_specific_data[0]) );
manufacturer_specific_data.data.p_data			= manuf_specific_data;
g_advinit.advdata.p_manuf_specific_data			= &manufacturer_specific_data;

g_advinit.srdata.uuids_complete.uuid_cnt	= ( sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]) );
g_advinit.srdata.uuids_complete.p_uuids		= m_adv_uuids;

g_advinit.config.ble_adv_fast_enabled		= true;
g_advinit.config.ble_adv_fast_interval		= (40.0 / 0.625);
g_advinit.config.ble_adv_fast_timeout		= 0;
g_advinit.evt_handler = NULL;

ble_advertising_init( &m_advertising, &g_advinit);

Hello,

Please make sure that you always check the returned error codes from the SDK functions in order to be alerted in the case that a function call unexpectedly fails.

Please also take a look at how you can use the advertising library to dynamically update your advertising payload with manufacturer specific data in the example from this blogpost.

Best regards,
Karl

The code I have included omits it, but there is actually an error checking process.
I have verified that no errors have occurred.

Hello,

Great - I did not see any, so I thought I should mention it just in case, but I am glad to hear that you already have it in place!

Best regards,
Karl

Please tell me what is the cause.

Hello,

I am not sure exactly what you are asking about here, could you please elaborate?

Have you had a look at the example in the blogpost I reference in my first comment?

Best regards,
Karl

The problem has not been solved.
However, since there is no longer a need to use “manufacturer-specific data,” it is closed.
