sd_ble_gap_adv_start hangs after disconnect

[Vitaliy]

Hello

I have a problem with restarting advertising after disconnect event. There are two scenarios:

In this case everything works fine:

1. I start advertising
2. Device connects
3. Device disconnects (It sends Disconnect command)
4. I restart advertising in disconnect event

In this case sd_ble_gap_adv_start hangs:

1. I start advertising
2. Device connects
3. Disconnect event occures because I go away from this device and connection gets lost. The other device doesn't send Disconnect event (because it simply too far away).
4. I restart advertising in disconnect event and chip hangs

There is my code:

case BLE_GAP_EVT_DISCONNECTED:            
        m_conn_handle = BLE_CONN_HANDLE_INVALID;
        advertising_start();
        break;
...

void advertising_start(void)
{
    uint32_t             err_code;
    ble_gap_adv_params_t adv_params;  

    memset(&adv_params, 0, sizeof(adv_params));

    adv_params.type        = BLE_GAP_ADV_TYPE_ADV_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);   // hangs on this line!
    APP_ERROR_CHECK(err_code);
}

I use nRF51822 with SDK 9.00 in peripheral mode with S130 softdevice

S130 9.0.0? That doesn't exist. I can't reproduce this. Could you do a sniffer trace of the behavior? Also consider editing your question to include the complete project that exhibits the behavior.
