Using Bluetooth low energy in linux command line
I am working on using the Bluetooth low energy modem with Linux. I am using the command line option for that i.e. hcitool . I am able to the find the devices using the command: $ hcitool scan
It is working fine for me, also I am able to broadcast my device using :
sudo hciconfig hci0 leadv
It is also working fine. But I want to add the services and characteristic to the modem device which can be detected by other device. I have tried sdptool add but it is not working for me. Does anyone know how to add the services and characteristics to the peripheral using the command line tools in ubuntu?
Edit: My modem is broadcasting but not able to explore the services and characteristic to the other BLE device. Now I am able to set the name of device using hcio name command
Edit: Now I am able to render the services and characteristic, by simultaneously running sudo hcidump command. But I am not able to track from where I am getting those services and characteristics. One definite observation is those services are rendering from the machine.
Solution 1:
SDP is absent in BLE. Broadcast/advertise frame and GATT client/server are used instead.
