Yes, the connection is established on 1M. Then, you request to switch to 2M, if the other device also supports 2M and accepts to use 2M, then the connection will switch to using 2M.

so from the snippet u have shared does this means that now the connection phy is set to 2M?

want to know by default was this value set to 1M?

Hi,

Call it in the BLE_GAP_EVT_CONNECTED event, in the ble_evt_handler() function.

Snippet:

        case BLE_GAP_EVT_CONNECTED:
            NRF_LOG_INFO("Connected.");
            err_code = bsp_indication_set(BSP_INDICATE_CONNECTED);
            APP_ERROR_CHECK(err_code);
            m_conn_handle = p_ble_evt->evt.gap_evt.conn_handle;
            err_code = nrf_ble_qwr_conn_handle_assign(&m_qwr, m_conn_handle);
            APP_ERROR_CHECK(err_code);

            NRF_LOG_INFO("PHY update requested.");
            ble_gap_phys_t const phys =
            {
                .rx_phys = BLE_GAP_PHY_2MBPS,
                .tx_phys = BLE_GAP_PHY_2MBPS,
            };
            err_code = sd_ble_gap_phy_update(p_ble_evt->evt.gap_evt.conn_handle, &phys);
            APP_ERROR_CHECK(err_code);

            break;

Hi,

kindly tell where to add this function sd_ble_gap_phy_update() so that PHY for connection mode is set to 2M in ble_app_template code nrf52832 sdk version 17.2 s132

I guess with the limited data on the primary advertising channels, there is minimal to no benefit using that.

You can change to 2M after connecting, using sd_ble_gap_phy_update()

You can only do primary adverting on 1M PHY and Coded PHY. Primary advertising on 2M PHY is not supported by the spec.
