[MQTT/SARAR4] Issue during MQTT publish
Hello Zephyr Community,
I am trying to use example in samples/net/mqtt_publisher.
I am on zephyr 2.0 release and I use SARA R4 driver to try this example.
I just changed prj.conf to use MQTT (not secured) on my own mosquito broker (on infomaniak server).
I don’t achieve to connect to MQTT broker and I always have following error message:
MQTT connect failed -111
Moreover, I tried to see what is send to SARA-R4 module (and what is its answer).
I can see that it loops several times on same command whereas command is ok and well understood by my SARA R4 module
Do you have any idea on what can happen ?
For your information, it works when I use zephyr 1.14.1 with 1st SARA R4 driver revision.
Thanks in advance for your help
