Once you have upgraded to Bluez 5.46 from the previous post;
You can perform a quick BLE test with this file
To start your BLE adventure;
sudo hciconfig hci0 leadv 0 #this sets LE advertising on and as ‘connectable’
./gatt-service #starts the service
The source for gatt-service;
inside the bluez/tools folder is all the source you need to get started with your own Linux BLE Applet.
How can I view the BLE service?
there are lots of BLE exploring apps, I use the “LightBlue” App on my iPhone.
