I'm running this on Linux. I can the below error only sometimes while running my program. It seems to immediately occur only once either the PoweredUpHub or PoweredUpRemote is visible to my computer's bluetooth, but other times it just fails immeidately. Most of the time, it works fine, but other times it doesn't.
