Hello Zephyr community,

I contact you because I have an issue when I run mqtt_publisher example

https://docs.zephyrproject.org/1.13.0/samples/net/mqtt_publisher/README.html

I have the following issue when I have multiple mqtt connection/disconnection (through tcp transport_connect function)

[try_to_connect:233] mqtt_connect: -2 <ERROR>

I have this issue after 10 connection/disconnection. The eleventh one is always failing.

As I said you I saw that this is failing when I try to run mqtt_transport_connect(client); in client_connect.

My configuration is the following one :

• MQTT (not secured)
• TCP/IPv4
• Broker on external server (not any issue on this one)

If you have any idea to help me

Thanks in advance

Best Regards

Guillaume
