[BLE]nRF52DK update PHY to 2M PHY with iPhone 8, but the callback indicate it's still 1M PHY.

This is my code, https://os.mbed.com/users/krenbluetoothsig/code/BluetoothLEGap/ You can check the latest commit out, compile and run it on Nordic nRF52DK. I use my iPhone 8 (iOS 12.1) to connect with nRF52DK, I could noticed that iPhone and DK updated the PHY to 2M PHY because they were preferred PHY, but the callback from mbed OS indicated that the PHY is still 1M PHY, they are mismatched. The callback is below, the phy.value() is always 1.

virtual void onPhyUpdateComplete( ble_error_t error, Gap::Handle_t connectionHandle, Gap::Phy_t txPhy, Gap::Phy_t rxPhy ) { if (error) { printf( "Phy update on connection: %d failed with error code %s\r\n", connectionHandle, BLE::errorToString(error) ); } else { printf( "Phy update on connection %d - Tx Phy: %d, Rx Phy: %d\r\n", connectionHandle, txPhy.value(), /*to_string(txPhy),*/ rxPhy.value() /*to_string(rxPhy)*/ ); } }
