nRF52840 Dongle advertising

[lucaN]

I'm trying to set up the Dongle pca10059. I'm using the softdevice 140 and segger studio. The code is from the SDK, the template example.

the main.c:

static ble_uuid_t m_adv_uuids[] = /**< Universally unique service identifiers. */
{
       //{BLE_UUID_DEVICE_INFORMATION_SERVICE, BLE_UUID_TYPE_BLE},
       {CUSTOM_SERVICE_UUID, BLE_UUID_TYPE_VENDOR_BEGIN}
};

When I'm using BLE__UUID_TYPE_VENDOR_BEGIN, I can't find the Dongle anymore with the nRF Connect App. (The LED starts to blink.) When I use 0x01 instead, it works. But the only service I see then, is 0x0001. 

in ble_cus.c:

uint32_t ble_cus_init(ble_cus_t * p_cus, const ble_cus_init_t * p_cus_init)
{
        if(p_cus == NULL || p_cus_init == NULL)
       {
              return NRF_ERROR_NULL;
       }

      uint32_t err_code;
      ble_uuid_t ble_uuid;

      p_cus->conn_handle = BLE_CONN_HANDLE_INVALID;

       ble_uuid128_t base_uuid = {CUSTOM_SERVICE_UUID_BASE};

       err_code = sd_ble_uuid_vs_add(&base_uuid, &p_cus->uuid_type);
       VERIFY_SUCCESS(err_code);

       ble_uuid.type = p_cus->uuid_type;
       ble_uuid.uuid = CUSTOM_SERVICE_UUID;

       err_code = sd_ble_gatts_service_add(BLE_GATTS_SRVC_TYPE_PRIMARY, &ble_uuid, &p_cus->service_handle);
        if(err_code != NRF_SUCCESS)
        {
                 return err_code;
        }

}

In ble_cus.h:

typedef struct ble_cus_s ble_cus_t;

#define BLE_CUS_DEF(_name) \
static ble_cus_t _name; \

/*#define BLE_SERVICE_DEF(_name) \
static ble_service_t _name; \
NRF_SDH_BLE_OBSERVER(_name ## _obs, \
BLE_SERVICE_OBSERVER_PRIO, \
ble_service_on_ble_evt, \
&_name)
*/
#define CUSTOM_SERVICE_UUID_BASE {0xA8, 0x47, 0xKJ, 0x0A, 0x1S, 0x4E, 0x95, 0xA2, 0x01, 0x47, 0xF6, 0x47, 0x00, 0x00, 0x64, 0x75}

#define CUSTOM_SERVICE_UUID 0x0001
#define CUSTOM_VALUE_CHAR_UUID 0x0002

typedef struct
{
uint8_t initial_custom_value;
ble_srv_cccd_security_mode_t custom_value_char_attr_md;
} ble_cus_init_t;

struct ble_cus_s
{
uint16_t service_handle;
ble_gatts_char_handles_t custom_value_handles;
uint16_t conn_handle;
uint8_t const uuid_type;
};

typedef struct ble_cus_s ble_cus_t;

uint32_t ble_cus_init(ble_cus_t * p_cus, const ble_cus_init_t * p_cus_init);

I made a few changes to use it with the pca10059. Because the template is for 10056. Might that be the problem?

Thanks in advance!

I made a few changes to use it with the pca10059. Because the template is for 10056. Might that be a problem?

Thanks in advance!

Certainly it could!

Have you had it working on the Dev Kit (PCA10056)  before moving to the Dongle (PCA10059) ?

If not, I would strongly recommend that you do!
