Tahu C CONNACK (3)

JakobKlocker opened this issue · comments

When attempting to connect to a Sparkplug B broker, such as ThingsBoard, using the provided C examples, I consistently receive a CONNACK (3) Error. This error appears when the mosquitto_loop function is called.

I've successfully connected and published data via the Python and Java libraries without encountering any issues. However, the problem persists exclusively with the C library.

I've spent the past two days experimenting with different settings, but unfortunately, I've been unable to publish any messages using the C library. Could there be specific differences or considerations unique to this library compared to the others that I might be overlooking?
