Default Advtertising config Setting

[Kawing]

Hi Nordic, 

There is a question about the default setting for Advertising PHY type. if there is no config value setting like case (PHY_1M ) . (all memory already set to 0 ).

case PHY_CODED  : 

            BLE_LOG_INFO("-->  BLE_Adv Range Mode set to %s", "PHY_CODED");

            cfg->config.ble_adv_primary_phy      =          BLE_GAP_PHY_CODED;

            cfg->config.ble_adv_secondary_phy    =          BLE_GAP_PHY_CODED;

            cfg->config.ble_adv_extended_enabled =          true;

        break;

        case PHY_2M     : 

            BLE_LOG_INFO("-->  BLE_Adv Range Mode set to %s", "PHY_2M");

            cfg->config.ble_adv_primary_phy      =          BLE_GAP_PHY_2MBPS;

            cfg->config.ble_adv_secondary_phy    =          BLE_GAP_PHY_2MBPS;

            cfg->config.ble_adv_extended_enabled =          true;

        break;      

        case PHY_1M     : 

            BLE_LOG_INFO("-->  BLE_Adv Range Mode set to %s", "PHY_1M");  

            cfg->config.ble_adv_extended_enabled =          false;

        break;

what is the default PHY setting after Initial ?  Thanks.

If there's no config set the default is 1mbps PHY without adv extensions.

Thanks for reply , and I would like to know what is the different between 1mbps and AUTO PHY?

Auto PHY means that you support all PHY's that the device can support. Whenever your application or a peer device requests a PHY change the SoftDevice will change to the requested PHY. 

If you configure your application to only support 1mbps then you won't be able to change PHY.
