Hi,
I'm trying to set up the connectable/scannable advertising. I took the app_beacon example and changed advertising parameters.
My final set up is:
#define APP_BLE_CONN_CFG_TAG 1 /**< A tag identifying the SoftDevice BLE configuration. */
#define NON_CONNECTABLE_ADV_INTERVAL MSEC_TO_UNITS(100, UNIT_0_625_MS) /**< The advertising interval for non-connectable advertisement (100 ms). This value can vary between 100ms to 10.24s). */
#define APP_BEACON_INFO_LENGTH 0x0D /**< Total length of information advertised by the Beacon. */
#define APP_ADV_DATA_LENGTH 0x0B /**< Length of manufacturer specific data in the advertisement. */
#define APP_DEVICE_TYPE 0x02 /**< 0x02 refers to Beacon. */
#define APP_MEASURED_RSSI 0xC3 /**< The Beacon's measured RSSI at 1 meter distance in dBm. */
#define APP_COMPANY_IDENTIFIER 0x0059 /**< Company identifier for Nordic Semiconductor ASA. as per www.bluetooth.org. */
#define APP_MAJOR_VALUE 0x01, 0x02 /**< Major value used to identify Beacons. */
#define APP_MINOR_VALUE 0x03, 0x04 /**< Minor value used to identify Beacons. */
#define APP_BEACON_UUID 0x01, 0x12, 0x23, 0x34, \
0x45, 0x56, 0x67, 0x78, \
0x89, 0x9a, 0xab
#define DEAD_BEEF 0xDEADBEEF /**< Value used as error code on stack dump, can be used to identify stack location on stack unwind. */
#if defined(USE_UICR_FOR_MAJ_MIN_VALUES)
#define MAJ_VAL_OFFSET_IN_BEACON_INFO 18 /**< Position of the MSB of the Major Value in m_beacon_info array. */
#define UICR_ADDRESS 0x10001080 /**< Address of the UICR register used by this example. The major and minor versions to be encoded into the advertising data will be picked up from this location. */
#endif
static ble_gap_adv_params_t m_adv_params; /**< Parameters to be passed to the stack when starting advertising. */
/*

}
The ADV_INTERVAl is defined as:
#ifndef ADV_INTERVAL #define ADV_INTERVAL 300 #endif
After running the app will throw the error: <error> app: ERROR 18 [Unknown error code]
I looked to another examples which have similar set up as mine example so I would not expect any error.
If I set m_adv_params.type = BLE_GAP_ADV_TYPE_ADV_NONCONN_IND (deafult setting of the example)
then everything is OK and I can catch sent packet via wireshark.
Did I miss something? For example some, GATT settings?
Thank you for help!
