<p>So I've got the driver now. The COM ports are being established in the device manager and I can get some data off of the device using the python driver. However, it still won't connect properly to the web portal (<a href="https://developers.aceinna.com/devices/rtk" rel="nofollow">https://developers.aceinna.com/devices/rtk</a>).</p>
<p>In the logs I'm getting the following warningshow up amounst the INFO messages:</p>
<p>2021-09-17 15:40:33,340 - WARNING: error happened when decode the payload of packets, pls restart driver: pack expected 36 items for packing (got 30)</p>

<p>The sn number of our device is  2075000309</p>
<p>I've tried with the v2.5.0 of the python driver (we were previously using 2.5.2) and google chrome. It does now seem to work, however we do occasionally get the error message:</p>
<pre><code>Exception when log device connection to db: HTTPSConnectionPool(host='api.aceinna.com', port=443): Max retries exceeded with url: /api/deviceConnections/log (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1108)')))
</code></pre>

Please ignore this problem for now, it does not affect your usage, but we will continue to reproduce this problem .So we need more information:<br />
1.What operating system do you use.<br />
2.How do you run the python driver？ exe file or source code.</p>
