https://devzone.nordicsemi.com/f/nordic-q-a/48147/multiple-mqtt-pub-at-qos-0Hi, I&#39;m trying to send multiple messages to a MQTT server at QoS 0 , but the client gets disconnected after +8 messages. I&#39;m able to send more then 8 if I add a delay of 1000 ms between each message, but it disconnects at +32 messages.

Are you using TLS or just plain TCP?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/192633?ContentTypeID=1Thu, 13 Jun 2019 10:34:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:12ab7e9f-a05c-44c9-8615-8eac7149fd1bmen<p>Hi Hakon,</p> <p>Do you think this could be an Network issue? Or is it because I&#39;m handling the MQTT application the wrong way?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/191922?ContentTypeID=1Tue, 11 Jun 2019 07:19:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:adb9aff4-b7fe-47e7-8885-c1a35818dce7men<p>I don&#39;t believe it is the server that is causing the issue. I have tried following servers, all with the same result:</p> <ul> <li>iot.eclipse.org</li> <li>test.mosquitto.org (but not working at the moment of writing)</li> <li>broker.hivemq.com</li> <li>Azure IOT hub</li> </ul><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/191667?ContentTypeID=1Fri, 07 Jun 2019 13:06:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e59572c1-7a19-45e0-82f1-c89d24c95ac7Hakon<p>Perhaps you should try a different broker, like mosquitto. Iot.eclipse.org can be quite unstable.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/191650?ContentTypeID=1Fri, 07 Jun 2019 12:23:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:69c99c6e-21b8-4108-bcf6-029e570c17dcmen<p>Yes</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/191641?ContentTypeID=1Fri, 07 Jun 2019 12:07:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:40a00774-bea4-4953-8e67-4865222b9d77Hakon<p>Are you using iot.eclipse.org as broker?</p><div style="clear:both;"></div>
