Multi ble_app_uart to one ble_app_multilink_central

[Stanley]

Dears, I would like to implement a solution for multi-nus(peripherals) to connect one ble_app_multilink_central(centrals). Is it the right way to implement multi-nus connecting to one central(blinky)? I have checked the developer zone about multi-nus with one central. Someone advises to follow this way for such kind of solution. I have tried to modify ble_app_multilink_central to connect just one nus(peripheral) at the first. I can connect the peripheral by uuid, but can't connect it by device_name. Have anyone can tell me how to get the device_name from adv. data?

Hi,

Have anyone can tell me how to get the device_name from adv. data?

The ble_app_multilink_central does this in the on_adv_report() function.

Snippet:

// For readibility.
ble_gap_evt_t  const * p_gap_evt  = &p_ble_evt->evt.gap_evt;
ble_gap_addr_t const * peer_addr  = &p_gap_evt->params.adv_report.peer_addr;

// Prepare advertisement report for parsing.
adv_data.p_data = (uint8_t *)p_gap_evt->params.adv_report.data;
adv_data.size   = p_gap_evt->params.adv_report.dlen;

// Search for advertising names.
bool found_name = false;
err_code = adv_report_parse(BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME,
                            &adv_data,
                            &dev_name);
if (err_code != NRF_SUCCESS)
{
    // Look for the short local name if it was not found as complete.
    err_code = adv_report_parse(BLE_GAP_AD_TYPE_SHORT_LOCAL_NAME, &adv_data, &dev_name);
    if (err_code != NRF_SUCCESS)
    {
        // If we can't parse the data, then exit.
        return;
    }
    else
    {
        found_name = true;
    }
}
else
{
    found_name = true;
}

if (found_name)
{
    if (strlen(m_target_periph_name) != 0)
    {
        if (memcmp(m_target_periph_name, dev_name.p_data, dev_name.size) == 0)
        {
            do_connect = true;
        }
    }
}
