bluetooth authentication using Linux SDK

Also I don't see hcid running nor hcid.conf is present in the file system. I thought blueZ needs them.

So how is it working? When I say working I mean I can establish a Bluetooth socket connection between my BeagleBone TiWi5 cape and PC and able to transfer raw bytes between them.

Hi Iftikhar,

You may change the shell prompt according to the following: http://bash.cyberciti.biz/guide/Changing_bash_prompt

Let me get back to you on the other questions.

Thank you for the suggestion. In what way changing the shell going to help?

Hi Iftikhar,

I thought your first question was about changing the shell prompt, or am I not understanding it correctly?

Sorry I should have put my first question  i.e

"How can we change it so it comes with the specified name at every bootup"

in a better way.

What I meant was that when I search on my PC for Bluetooth devices, I see this BeagleBone device showing up as "am335x-evm-0". On BeagleBone I can change this name via

hciconfig hci0 name myDesiredName

and then my PC shows it as "myDesiredName", but after bootup this "myDesiredName" is lost and "am335x-evm-0" is back up.  So how can this name be permanently changed so that it always shows "myDesiredName" at every bootup without the need to run  the hciconfig command.

Hi Andrii,

You will have a section called "Name". in Main.conf file please change it to the name you desire. 

Thanks & Regards,

Sundeep.

It didn't work. I tried the following. it still shows "am335x-evm" as the name.

This is the copy and paste of the portion of  /etc/bluetooth/Main.conf

[General]

# List of plugins that should not be loaded on bluetoothd startup
#DisablePlugins = network,input

# Default adaper name
# %h - substituted for hostname
# %d - substituted for adapter id
#Name = %h-%d
Name = Ifti_BB

Hi Ifti,

This means that, you will have a config file in "/var/lib/bluetooth/<BDaddress>/config". There is a name field which you should change. 

First time when you Turn ON Bluetooth, the above file is created based on “main.conf” and for the subsequent operations it is read from the above file.

Thanks  & Regards,

Sundeep.

I went and deleted the folder " "/var/lib/bluetooth/<BDaddress>" and then rebooted my BB. As you had mentioned, now the name specified in Main.conf shows up correctly when my PC searches for bluetooth device. Thanks for the help!

I have another question: Currently I am doing the following on BB

hciconfig hci0 &> /dev/null
insmod `find /lib/modules/ -name "gpio_en.ko"`
hciattach /dev/ttyO1 texas 3000000 &
hciconfig hci0 piscan &> /dev/null

After it I am able to pair to the BB from my PC without any authentication. How can I enforce authentication so that no one can pair to it unless they provide the correct PIN?

Thanks. That was helpful. I was missing to run the agent. Where is the BlueZ forum? 

agent --path /org/bluez/agent 0000 &> /dev/null &

Hi Ifti,

There are many open BlueZ forums. Like http://www.bluez.org/contact/

Thanks & Regards,
