https://devzone.nordicsemi.com/f/nordic-q-a/75027/multiple-mqtt-clients-using-nrf9160Has anyone done multiple mqtt client connections from an nrf9160? Is it simply a matter of using the mqtt api and defining multiple client structures with unique rx/tx buffers assigned to them? Or are there any limitations imposed by the modem softwareen-USTelligent Community 13Wed, 12 May 2021 07:52:00 GMThttps://devzone.nordicsemi.com/thread/309388?ContentTypeID=1Wed, 12 May 2021 07:52:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:12a7beff-71fe-412c-b9f4-08e6ba868312&#216;yvind<p>Hello,&nbsp;</p> <p>&nbsp;</p> [quote user=""]Is it simply a matter of using the mqtt api and defining multiple client structures with unique rx/tx buffers assigned to them?[/quote] <p>&nbsp;Yes,&nbsp;there should be no issues. You need to have two separate mqtt_client structure instances and handle them separately (i. e. separate init, connect etc.). There&#39;s no fixed configuration like client port in the MQTT library, all the data is kept within the mqtt_client context so you can maintain as many MQTT connections as you want (in the boundaries of the available memory of course)</p> <p></p> <p>Kind regards,<br />Øyvind</p><div style="clear:both;"></div>
