Configuring data in BLE Advertisement header

[Michael Zeng]

Hi,

I'm trying to construct a BLE advertisement whose header satisfies the following requirements:

I am configuring my BLE advertisement as such, and I believe this is correct:

uint8_t manufDataBuff[]={0xFA, 0xFF, 0x0D, 0x77, 0x02, 0x10, 0x31, 0x32,
                         0x33, 0x34, 0x35, 0x36, 0x37, 0x38, 0x39, 0x30,
                         0x31, 0x32, 0x33, 0x34, 0x35, 0x36, 0x37, 0x38,
                         0x39, 0x30, 0x00, 0x00, 0x00};
struct bt_data dt_bt_conn_ad[] = {
    {
        .type = 0x16,  // Service Data
        .data_len = sizeof(manufDataBuff),  // 30 bytes
        .data = manufDataBuff,
    }
};

struct bt_le_adv_param param = *(BT_LE_ADV_NCONN);
param.interval_min = 1000;
param.interval_max = 1000;

// setting BT_LE_ADV_CONN_NAME instead of BT_LE_ADV_CONN automatically sets a scan response containing the device name
int err = bt_le_adv_start(&param, dt_bt_conn_ad, ARRAY_SIZE(dt_bt_conn_ad), NULL, 0);

I don't currently have a way to scan for and read out the data in the header to confirm. Do you know if my code would satisfy the requirements, particularly for the Preamble and Access Address (I couldn't find a way to explicitly set the PHY to LE 1M or the Access Address, but I assume these are correct by default?).

Thanks,

Michael

Sorry we are running bit short in resources due to summer holidays in Norway. I will look into your description and answer you on Monday. Thanks for your patience so far.
