I have been using tools (
gatttool etc) from the BlueZ bluetooth protocol stack to connect to my BLE device. I have been able to successfully connect to the device and obtain data off it. My application however demands faster transfer of data from the BLE device (BLE peripheral device) to my computer (BLE master device).
One of the ways I can make the connection run faster is by making the connection interval shorter on the main device but I have no idea how to do that in my Linux system.
