Hi AJ,

Were you able to make your Nordic device iBeacon Firmware discovered by an iOS application? We're currently planning on writing this firmware for a solutions.

Thanks! -Eric

This is useful. Can you suggest how to optimize this code when I need to broadcast 3 times every second?

I am trying to build iBeacon profile based on the above mentioned code. I have few doubts. Is it possible just initialize all the above mentioned parameters in the main loop and just run the softdevice forever. I would like to advertise indefinitely. so I am using BLE_GAP_ADV_TIMEOUT_GENERAL_UNLIMITED in non connectable mode.My main loop looks something like this and I am not waiting for any event. Just broadcasting id and my application does not run forever but just initializes softdevice.

......

<< above example code>>

int main(void) { ble_stack_init(); radio_notification_init(); gap_params_init(); advertising_init(); sec_params_init(); advertising_start();

}

Does the softdevice run forever after this. I would like to power optimize it. Does device goes to sleep between advertising events. I would like to advertise 3 times per second. Is this the best way to do it? I would like to know how can disable all other functions except broadcasting to optimize for power. How can I do it?

Thanks! But have you tried it? Doesn't seem to work for me. Looking at the code, you are missing a couple of bytes from the beginning of the advertising payload if I'm not mistaken:

Even though Apple haven't supplied much details on iBeacon, it isn't hard to start one iDevice as an iBeacon, following Apple's documentation, and then replicating the advertising format seen there on an nRF51.

This could for example become like this:


typedef __packed struct
{
    uint16_t unknown1;
    uint8_t uuid[16];
    uint16_t major;
    uint16_t minor;
    uint8_t unknown2;
} clbeacon_info_t;
...
static void advertising_init(void)
{
    uint32_t      err_code;
    uint8_t       flags = BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED;
    ble_advdata_t advdata;
    
    uint8_t uuid[16] = {0x01, 0x12, 0x23, 0x34, 0x45, 0x56, 0x67, 0x78, 0x89, 0x9a, 0xab, 0xbc, 0xcd, 0xde, 0xef, 0xf0};
    
    clbeacon_info_t beacon_info;
    beacon_info.unknown1 = 0x1502;
    memcpy(&beacon_info.uuid, &uuid, sizeof(uuid));
    beacon_info.major = 0x3412;
    beacon_info.minor = 0x7798;
    beacon_info.unknown2 = 0xC5;

    ble_advdata_manuf_data_t manuf_specific_data;
    manuf_specific_data.company_identifier = 0x004C;
    manuf_specific_data.data.p_data        = (uint8_t *) &beacon_info;
    manuf_specific_data.data.size          = sizeof(beacon_info);
    
    // Build and set advertising data
    memset(&advdata, 0, sizeof(advdata));
    
    advdata.name_type               = BLE_ADVDATA_NO_NAME;
    advdata.flags.size              = sizeof(flags);
    advdata.flags.p_data            = &flags;
    advdata.p_manuf_specific_data   = &manuf_specific_data;
    
    err_code = ble_advdata_set(&advdata, NULL);
    APP_ERROR_CHECK(err_code);
}


/**@brief Start advertising.
 */
static void advertising_start(void)
{
    uint32_t             err_code;
    ble_gap_adv_params_t adv_params;
    
    // Start advertising
    memset(&adv_params, 0, sizeof(adv_params));
    
    adv_params.type        = BLE_GAP_ADV_TYPE_ADV_NONCONN_IND;
    adv_params.p_peer_addr = NULL;
    adv_params.fp          = BLE_GAP_ADV_FP_ANY;
    adv_params.interval    = APP_ADV_INTERVAL;
    adv_params.timeout     = APP_ADV_TIMEOUT_IN_SECONDS;

    err_code = sd_ble_gap_adv_start(&adv_params);
    APP_ERROR_CHECK(err_code);
    nrf_gpio_pin_set(ADVERTISING_LED_PIN_NO);
}

Only iOS devices can currently be iBeacons. (Yes, you read that correctly).

Apple, to date, has been pretty tight lipped about plans outside of iOS devices.

From what I've read this should be something read-only on the device, so my question is how can I read this? Any thoughts or suggestions?

From what I gather looking at the APIs you linked, that is a readonly property in the CLBeacon class, so I assume it is populated by iOS when you perform a scan for beacons nearby.

You will likely have to include certain parameters in your advertisement data and Attribute table to tell iOS that your device is indeed a beacon.

Since this not seems to be covered by the freely available docs in developer.apple.com, I assume this is probably protected under the MFi program and you'll need to contact Apple directly for more information.
