Recently when I was playing with creating Docker images I came across really strange error during creation of a container that doesn’t say much (not to me):

standard_init_linux.go:175: exec user process caused "exec format error"

Do you want to know what bluetooth devices are in the range of your raspberry Pi unit and then act accordingly? Now it’s easier than ever before because with version 0.1.3 rhiot comes with bunch of new IoT components and one of them is Camel Bluetooth component which will allow you to list bluetooth devices working in surrounding area. There is also possibility to list services of given device if you want to know how to interact with it.
