Bluetooth Low-Energy for Linux API

Question

I have a device with several GATT user services, and I would like to write a Linux program to interact with it. After some searching, I found out that Linux uses BlueZ to process the Bluetooth LE protocol. I am using Ubuntu 15.10 with BlueZ 5.35, but I cannot figure out how to use this BlueZ from a user space program. I can not find the API documentation anywhere, there are no tutorials, examples, nothing. Is it possible to use this BlueZ stack for something other than just connecting to Bluetooth devices with default services? And if so, where is the documentation? (Preferably, the C / C ++ API, but at this point everything goes)

Answer 1

It would be simpler and faster to write a shell script in Linux to do what you need. BlueZ teams are relatively simple and straightforward, and there are many tutorials and questions on how to use them.
