Hello,

We are trying to gather data of bike powermeter on one usb stick. We openthe channel got lots of RX_Fail..
Have you an idea of the reason of this issue ? (it's works fine when we connect an heartbeat device in the same way).
I provide an exemple of code and the output we got.

For this test we only write in console on messages RX_Fail et RX_Fail_Go_To_Search

Thanks for your help.

Code exemple :

device0 = null;
                device0 = new ANT_Device();   // Create a device instance using the automatic constructor (automatic detection of USB device number and baud rate)
                device0.ResetUSB();
                device0.ResetSystem();
                Thread.Sleep(500);
                device0.setNetworkKey(USER_NETWORK_NUM, USER_NETWORK_KEY, 500);
                  
                device0.enableRxExtendedMessages(true);
                device0.deviceResponse += new ANT_Device.dDeviceResponseHandler(DeviceResponse);    // Add device response function to receive protocol event messages
                device0.serialError += OnSerialError;

                var c1 = device0.getChannel(0);
                c1.channelResponse += new dChannelResponseHandler(ChannelResponse);
                c1.assignChannel(ANT_ReferenceLibrary.ChannelType.BASE_Slave_Receive_0x00, USER_NETWORK_NUM, 500);
                c1.setChannelID(42747, false, 11, 0, 500);
                c1.setChannelPeriod(8070, 500);
                c1.setChannelSearchPriority(0);
                c1.setChannelFreq(57, 500);
                if (c1.openChannel(500)){
                    Trace.WriteLine("Open power channel");
                } 

exemple of output :

Try moving the USB closer to the power meter. Confirm that you have set the channel period to match the profile document.

So it was both, it seems for the power meter we have test we need to touch the usb stick for detect the sensor (probably the sensor have a trouble), for other we detect them at many meters. We also mix the channel period.
Thanks for your help !
