How to establish serial connection with Bluetooth device on Win7
<p>I am really frustrated and have no idea where to search for an answer.
Currently I am working on a project to detect drowsiness with an ECG device (<a href="https://www.zephyranywhere.com/products/bioharness-3" rel="nofollow noreferrer">Zephyr Bioharness 3</a>). The device works but I can't find it with windows (<a href="https://support.microsoft.com/en-us/help/15290/windows-connect-bluetooth-device" rel="nofollow noreferrer">For example like this</a>). I tried several things:</p>

<ul>
<li>Find the device with my Smartphone -> works</li>
<li>Find the device with an Ubuntu on the same Laptop -> works</li>
<li>Connect directly on Win7 via Bluetooth with this Python Script: <a href="https://gist.github.com/darkopetrovic/2127217" rel="nofollow noreferrer">Gist</a> -> connects and sends data</li>
<li>Find other Bluetooth devices with my Laptop on Win7 -> Bluetooth radio is dound</li>
<li>COM port for (virtual) serial connection to a bluetooth device (device manager)</li>
</ul>

<p>What I am trying, is getting this script to work: <a href="https://github.com/darkopetrovic/ZephyrApp" rel="nofollow noreferrer">ZephyrApp</a>. Beside some compatibility problems with <code>QT</code> and <code>serial</code> (which I was able to fix), the programm hangs here <a href="https://github.com/darkopetrovic/ZephyrApp/blob/master/zephyr/protocol.py#L49" rel="nofollow noreferrer">protocol.py</a>. I suspect the problems of not finding the device relates to the problems with the program. I know this is very special case, but hope anyone has an idea, how to fix this.</p>

<p>Regards,
paul</p>

<p>EDIT: Another PC with Win7 can't detect the device as well, it seems it is a Windows problem.</p>
