I need to do a IOT project with my pi-3 as a homework assignment, but I have an unexpected problem.
My friends and I did exactly the same things to build the operating system and project, which is using kafka server to communicate each other.
My friends' projects work fine, but mine is giving some errors on the process of using kafka-python. The errors are like
no brokers available and
no available kafka server.
Is it possible that the Pi holds data that can cause errors without the SD card? If so, is there any way to fix it?
