<![CDATA[Need more help with implementing for(each)]]>I am still lost with how to define the "for" variable. I understand the container, but unsure about the variable.
In this case my container is "RemoteDevicesList" and I want to retrieve humanly readable items from it - address and name .

Can I find "common description" as a variable from the doc?

I tried using debug for such purpose, but was not successful finding the name for the "level". . (Does *d_otr has a "name" ?)

There are TWO different QList in my snippet. The first one fails as error posted.

correct

no viable conversion from 'QList<QBluetoothHostInfo>' to 'QList<QBluetoothDeviceInfo>'
QList<QBluetoothDeviceInfo> RemoteDevicesList_TEMP = localDevice.allDevices();

This warning does not come from the for() but from the assignment and I wrote what's wrong (even I only said what the compiler error already told you).

Sorry, but I included code for working for(each) , There are TWO different QList in my snippet. The first one fails as error posted.

RemoteDevicesList.append(info);

QList<QBluetoothDeviceInfo> RemoteDevicesList_TEMP = localDevice.allDevices();
RemoteDevicesList_TEMP.append(info);

QList<QBluetoothHostInfo> BT_HostInfo = localDevice.allDevices();


for (auto  localDevice : RemoteDevicesList_TEMP)
{

however I am getting this weird error - I do not get where is the

QBluetoothHostInfo

coming from

my list is

QBluetoothDeviceInfo
