nobody_19: We added support for the 2Mbps PHY in S132 v5.0.0 and in all subsequent versions of the SD you will get the BLE_GAP_EVT_PHY_UPDATE_REQUEST in the application when the Central sends a LL_PHY_REQ. This needs to be handled by calling sd_ble_gap_phy_update, see Peripheral PHY Update. So if you are not handling this event in your application then you need to add the following snippet

 case BLE_GAP_EVT_PHY_UPDATE_REQUEST:
        {
            NRF_LOG_DEBUG("PHY update request.");
            ble_gap_phys_t const phys =
            {
                .rx_phys = BLE_GAP_PHY_AUTO,
                .tx_phys = BLE_GAP_PHY_AUTO,
            };
            err_code = sd_ble_gap_phy_update(p_ble_evt->evt.gap_evt.conn_handle, &phys);
            APP_ERROR_CHECK(err_code);
        } break;

to the ble_evt_handler() function in main.c.

It looks that the onePlus does a PHY request, which the GalaxyNote does not. Why is the SD not answering to the onePlus PHY request? Do I have to configure something?

nobody_19: The on-air trace only show advertisment packets, please make sure that you capture the connection process as well. Can you try to capture a new trace when you connect to the nRF52832 with the OnePlus?

Can you please capture a on-air trace of the communication between the nRF52832 and the two phones using the nRF Sniffer and nRF5x DK?

Best regards
