Just some context to explain my question :
My application can pair 5 types of sensor (Hr, Speed, Cadence, Combined S&C, Power).
The value of the sensor id, device type and transmission type are all stored for easy pairing when the user starts a bike workout.

When the workout is started, all necessary channels are opened (up to 4 channels) using the previously stored id of the sensor.
Now because I know that all the sensors ID should be good (user paired them). I set an infinite timeout on the channel search, so the user have time to do whatever he wants before the workout :

bStatus = pclMessageObject->SetChannelSearchTimeout(Channel, 255, MESSAGE_TIMEOUT); 

This is all working properly if the channel find a device, but if the channel doesn't find one, I cannot close the channel and the channel is left in an "infinite search" it seems.

Code for closing the channel (the application sends the flag closeChannelNow=true when the workout needs to end and close all channels):

if (closeChannelNow && antThreadRunning) {
                if (!threadStopped) {
                    qDebug() << "OK Closed window,, Closing Channel Now!";
                    pclMessageObject->CloseChannel(pclMessageObject->GetChannelNumber(&stMessage;), MESSAGE_TIMEOUT);
                    threadStopped = true;
                }
            } 

Is there a command or a way to end the search manually? Or a way to force a channel close ? My closeChannel command get ignored even if the channel is open.

Thanks in advance!

Did you try to unassign the channel instead of closing it?
Technically speaking the channel isn't open before the search succeeds, so it's not too strange that close() doesn't work.

Thanks for your reply,

In fact it has been resolved now, the problem was on my side.
I suspect I was closing the channel but not stopping the "Demo::MessageThread"

I changed my closing channel code recently not sure what fixed it:
C++ Code:

/// Workout finish, close open channels
            if (closeChannelNow && antThreadRunning) {
                if (!threadStopped) {
                    threadStopped = true;
                    qDebug() << "OK Closed window, Closing all open Channel Now!";
                    foreach (int i, lstOpennedChannel) {
                        qDebug() << "Got to close channel:" << i;
                        pclMessageObject->CloseChannel(i, MESSAGE_TIMEOUT);
                    }
                }
            }

As soon as the workout begins, the sensor's unique identifier is retrieved from memory and used to open the appropriate channels (up to a maximum of four).
At this point, I am confident that all of the sensors' IDs are functioning properly (user paired them). I made the channel search timeout limitless, giving the user plenty of leeway before the operation timed out. penalty kick online
