Re: [TCP/MQTT] Connection issue

Hello Zephyr Community,

I found where something is wrong.
Indeed in net_context_get function, I saw that I reached CONFIG_NET_MAX_CONTEXTS (equal to 10 in my prj.conf).
For your information, I use UBLOX sara r4 driver (on zephyr 1.14.1 as I mentionned in my previous mail) and I wonder if contexts are well managed in this revision, especially when socket is closed ? 

Thanks in advance for your help

Best Regards,

Guillaume

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
