BLE at the wrong end of a learning curve and trying to piece things together. Perhaps I could just give a rough outline of the project. I want a Linux device to listen for advertisements from a particular BLE sensor and connect to those sensors, as and when they appear. Once connected, the Linux device can send commands to the sensor, to turn on/off an LED or request sensor data from each of the connected sensors. The Linux kernel is 4.15 is an Ubuntu 16.04 based system. I was looking at the latest bluez-5.50 doc directory but didn't see a file for gap.txt, but adapter-api.txt looks like the API I'm looking for. I'm trying to do this from Python, so currently thinking of using DBus interface, another learning curve to address. So after all that a specific bluex questions. I'm missing things, and possibly incorrectly assuming that I need a certain kernel specified for bluez5.50, but can't see any mention of versions of bluez relating to versions of kernel. Secondly bluez-5.50 appears to be building an applicaiton, so I assume that application has to be running to interface to Linux Kernel bluetooth stack and handle the DBus API. So bluez should be a system service just started on powerup? Thanks for any help, I get the impression that this list is predominately for guts of the Linux Kernel's bluetooth stack, but user side list is hard to find. Thanks again John
