Hello,
I am a beginner student and I think this is the kind of misunderstanding on my part. I program on the Thingy 1.4.0 with the SDK 1.4.2. I create my own project to learn a little more about the embedded world. In this project I have several threads (Collect sensor values, connect to NB-IoT, connect to MQTT, LED and Button, send MQTT data).
I currently have a problem with my MQTT thread because the CONNACK events don't seem to be triggered. I receive the error MQTT disconnect -57. I can't find the origin of the problem. Do you have an idea to share? I have tested the simple MQTT and I use a lot of the functions and the one I modified were tested in a simple project without thread and it works. I think it has a link but I don't know how to solve it.
Thank you.
I attach my project here and the log:
