Fedora :: Connect A Bluetooth Device With The Command Rfcomm?
Mar 11, 2010
First, excuse me for my bad english I want to connect a bluetooth device with the command rfcomm. In a terminal, I put the command :
Code:
rfcomm connect 0 00:80:98:E4:07:53
And the system answers :
Code:
Connected /dev/rfcomm0 to 00:80:98:E4:07:53 on channel 1
Press CTRL-C for hangup
On fedora 10, or 11, I can use this command with all users. On fedora 12, only the root user can connect and use this device. Other users have the message :
Code:
Can't open RFCOMM device: Permission denied What can I do to resolve this problem?

Things I have tried so far:Followed tutorials found here at [url] and [url] None of which worked.
Some output from what appears to be a valid connection:
I have run sdptool browse and found my device
I have used hcitool scan and found my device
I have done a cat of /dev/rfcomm0 and seen data streaming
I have seen a process id for gpsd as well as seen a listneing port for gpsd
I have been unable to get either gpsdrive / xgps / tangogps to see gpsd. All report it as not running.

I'm writing a phone app for Android that connects to a bluetooth RFCOMM device in my car. My phone app talks AT commands with it. For development work, I often need to communicate with the device to try different commands and things.
My neighbors are starting to think I'm weird because I sit in my car for hours on end with my laptop screen shining on my face, typing away like a script kiddie.
I'd much rather configure one of my many Linux servers to act as a bluetooth RFCOMM device and allow me to connect to it (indoors, while I sit on my couch).
I imagine I have to start with something like
sdptool add SP
But then what?
I'm perfectly happy writing a perl app to handle the I/O, but I just don't know how to make the bluez stack accept connections and subsequently pipe that stream to a perl app.

I have a nifty new headset (a JawBone icon�the noise cancellation is incredible) and I've successfully connected it to my Karmic laptop (64 bit, for the off chance it makes a difference). The trouble is, I only occasionally want to connect it to my laptop; I mostly use it with my mobile 'phone.
The two devices fight over my new toy a lot, and invariably the laptop wins, contrary to what I want. It seems a pain to have to rediscover the headset every time I want to use VIOP or whatever, so is there a way to add a device to Karmic's Bluetooth list, but not have it connect whenever it sees it?

I have laptop with bluetooth and I bought PS3 bluetooth remote. In windows this remote is working with EventGhost and I would like to use it in Fedora as well. This remote has to be paired without a pin code, which is how I paired it in windows.In Fedora, however, there is no such option "no pin" when using a standard way to connect bluetooth device.How can I pair this remote in Fedora?

When a bluetooth controller I have connects I'd like a program launched (qjoypad) so that I can use it has a mouse. The controller has to be on before launching qjoypad otherwise qjoypad will not work.
So I was wondering if there is a way to launch a script when my controller connects, and then possibly when it disconnects to launch another script killing the qjoypad process.
EDIT: I created a script that checks if /dev/input/js0 exists, if it does then qjoypad is created
Code:
#!/bin/bash
while true; do
if [ -c "/dev/input/js0" ]; then
qjoypad

I use fedora12-Gnome as my major desktop OS. Every basic need was fulfilled , until I tried Fedora12 KDE and now Fedora13 KDE. The problem is with Bluetooth connectivity to my cell phone device. It connects to the cell phone and set trusted but I can't seem to see any option of "Browse files on Device". Does that mean in KDE I actually can not browse my Bluetooth connected devices?

I'm running Gnome with the bluetooth applet and I have to explicitly use the applet, select the mouse and tell it to connect. It automatically connects just fine when I boot into windows.
I have the same problem with both a Microsoft bluetooth mouse 5000 and a "BLUETOOTH HID v1.02 Mouse [Interlink Bluetooth Mouse]".

I've been having trouble in a couple of distros (including when I had windows installed..) getting my bluetooth working,
I have a dell vostro 1720, and the specs from dell insist there's a bluetooth adapter installed, and the laptop even has a little light which (ostensibly) indicates data being transmitted via bt... and, it's enabled in the bios.
though, dmesg | grep bluetooth
gives no results.
I've read comments on dell bluetooth for other dists, but can't seem to find any deb-specific recommendations.
So, how do i confirm that this laptop does *in deed* have a bluetooth adapter.. and... if there is one... how do let the kernel know about it?

I'm using Ubuntu 11.04 and bluetooth turn/off is not possible. However, with 2.6.37 kernel it is possible. Now i have gathered whole info about the device(mac adress, usb port etc) from 2.6.37 and what i need is to somehow use those info in kernel 2.6.38 so that bluetooth works.
lsusb in 2.6.37 (while bt is on)
Code:
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 002: ID 1241:1603 Belkin Keyboard

I am developing an application which communicates with a bluetooth device.I do not want the user to pair or unpair the device using the Bluetooth applet or command line, but I want to automate the pairing process through my application. The application will scan and find the bluetooth devices in the proximity of the computer, and automatically pair the required device without any user input.Where should I look for the relevant APIs?

I have just installed the last FC distro, and everything works good, except the wireless network.I have a Linksys N-Ultra WirelessN USB wifi card, model WUSB600N.It uses the rt2x00 driver, concretely the rt2870 driver (at least, thats the driver included in the original device drivers CD).Right now, the problem is that i don't know how to make my Fedora 12 to enable and/or connect to internet.

Currently my setup is a road runner cable modem connected to a desktop via a ethernet cable. The networkmanager lists "Broadcom BCM440-BO 100BaseTX" device not managed. I've turned off the power to both the cable modem and the computer. I then turned on the power to the cable modem and then the computer. If I try the firefox browser, it can not connect to the internet.

I updated quite a lot - kernel, selinux policies, initscripts, glibc and a lot more - and after reboot one filesystem does not mount. It says:Command failed: Can not access device... and asks for password. This is: RAID -> LVM (mirrored) -> LUKS -> ext3. Similar filesystem (raid->lvm(not mirrored)->luks->ext3) mounts fine. Mounting the problematic system by hand works fine. During boot, the lvm blockdev is named by UUID in crypttab, and the name used in fstab.
Of course I removed it from fstab to boot now. I tried downgrading initscripts so far, will try others. What I also noticed is that the emergency shell (bash) complains about something, I'd need to write it down next time I reboot; also "lvs" fails when / is ro, but maybe that's normal, dunno.Googling for the error message brought something about cryptsetup, but I didn't upgrade it (there is no upgrade available), and all I gather from it is that the error message might really mean something else, like device is already mapped.
It is probably something related to lvm mirrors, maybe also to luks, though the only related package in the list is the kernel, maybe the module-init-tools. SELinux seems not to be the cause, booting with permissive has the same problem. What I wrote above, leads me to thinking that luks is trying to set up lvm mirrors in parallel as they have the same uuid, but a) later during boot the mapping name is not there b) I have no idea what reads crypttab

After a lot of messing around and research, I figured out how to actually get my bluetooth headphones to connect and stay connected. Although once I shut them off, remove the device and re-add it using Blueman.
Right now, `pavucontrol` shows "Headphones (unplugged)" and there is no sound coming out of the speakers. But there is no sound coming out of the headphones either. They are set to the fallback. I've opened `alsamixer` and made sure everything was turned up. Still, no sound.
Since `bt-audio` isn't on Jessie, I don't know what I should do. It seems like this may be the missing step but I am unsure.

My onboard bluetooth is not being detected by SUSE 11.4. Fedora 14 has no problem detecting the hardware, but it just doesn't show up in SUSE 11.4. I have included a few outputs:
lsusb:
Code:
Bus 008 Device 002: ID 045e:0745 Microsoft Corp. Nano Transceiver v1.0 for Bluetooth
rfkill list
[Code]....
If I plug in a dongle, the Bluetooth icon shows up in the notification bar, and I'm able to add and remove devices normally. Is there support for my onboard bluetooth device?
