Hello John, There are various Python examples available in the tree under the test directory: https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/test There are a number of Python libraries that have been implemented to help with what you are looking to do. There is a list of some of them at: https://github.com/ukBaz/python-bluezero/wiki I hope that helps.
