General :: Redirecting Serial Data To An External Devices Using Bluetooth?
Apr 24, 2010
i have the following challenge: i have a Bluetooth GPS device that i have connected to my linux notebook. but now i also want to use the same device (or better, GPS data stream) for my Navigation device (HP Ipaq with TomTom). make an serial port bluetooth service (sending) that my Navigation device can connect to. copy the incoming bluetooth serial port data stream to the outgoing bluetooth serial port.
i have already installed GPSD so i have the TCP port where the GPS data is available for everything on my notebook. but now i also want it to send it out through bluetooth.
1. is there someone out there who already did this?
2. how to make an bluetooth serial port service on Fedora 12?
3. how to copy a data stream from 1 device to the next device?

i have a bluetooth modem (BlueSMiRF) that is connected to Arduino Duemilanove. I am trying to see serial communication messages from the bluetooth modem.
I have Blueman Device Manager that enabled SPP (Serial Port) and it says :
Code:
Serial port connected to /dev/rfcomm0
How do I see the serial communication on this?
I tried on console
Code:
$rfcomm listen 0
but it's stuck at

Waiting for connection on Channel 1
Is there any other way to listen (and also send) to serial comm msgs on bluetooth?

I have an application where I am sending data via serial port from PC1 (Java App) and reading that data in PC2 (C++ App). The problem that I am facing is that my PC2 (C++ App) is not able to read complete data sent by PC1 i.e. from my PC1 I am sending 190 bytes but PC2 is able to read close to 140 bytes though I am trying to read in a loop.Below is code snippet of my C++ AppOpen the connection to serial port
Code:
serialfd = open( serialPortName.c_str(), O_RDWR | O_NOCTTY | O_NDELAY);
if (serialfd == -1)

I am using read() in c++ to get data from a serial port. However, if no data is available on the serial port the function blocks until dta arrives.Example code:
//------------------------------------------------------------
char m_readBuffer[255] = {0};
char* p_curChar = m_readBuffer;
[code]...

I have been trying out serial and parallel data communication on Fedora 13 Beta. I can easily see the list of serial ports through:
Code:
setserial -g /dev/ttyS[0-3]
And can also write some data through:
Code:
ll > /dev/ttyS0
But I am unable to see parallel ports
I can see something like:
Code:
/dev/parport0
But when I try out:
ll > /dev/parport0
It throws error.

Minicom was running fine two days ago capturing data from a gage device via a serial cable. Yesterday, users of the data started complaining that they were not receiving any data.
The minicom status line reads offline. Is this part of the problem or is this normal (I never really noticed it before.) All settings on the gage device match the minicom settings.

I did a forum search and too much came up that was not the answer I was looking for. I have only Linux devices at work and I was wondering how do Linux Administrators connect to Cisco devices via serial console cable. Cisco recommends 'Hyper Terminal' which was a Windows add-on applications licensed to XP. I think Vista and 7 no longer have the license to use Hyper Terminal. Regardless I don't have any versions of Windows and would like to use a serial cable from Com port 1 to the console port on the device. I can't use SSH since some devices don't support SSH and or I have to do a password recovery.

Find external and internal devices attached to a system in Linux
How can i find through terminal that which devices are external and which are internal.
By external i mean devices attached to USB port. For Example, USB Drive, Portable USB HardDrive etc
By internal i mean devices attached internally. For Example, SATA Harddisk etc.

I was using V9 and upgrade to V10 and now my logins in my inittab do not work. I realize that is file structure is outdated so I made individual run files for each of my serial devices under event.d ( such as TX0000 - rc....etc) - all this works but i need to manual type initctl start TX000o to get logon for my serial devices. I would so much like them to automatically start on bootup.

My bluetooth devices disconnect after a period of inactivity (not sure exactly how long). They're being connected with:
sudo hidd --connect
And I've made no edits to any bluetooth related system files so it should be default settings throughout. I would like them to stay connected indefinitely and it would be even better if they would stay connected through reboots.

About 7 years ago I setup a Redhat system with 8 serial terminals and 8 serial printers, this is still running but I need to get another system running so the original can be taken down for maintenance. The printers are ancient Newbury data dot matrix wide carriage with 7 data bits receive 8 data bits transmit Xon/Xoff flow control. Now I remember setting the transmit and receive data bits as above but after 7 years can't remember where.

I am using Ubuntu, now installed KDE (kubuntu) and I have Bluetooth working and enabled but for some strange reason the bluetooth scan is not finding any devices in spite of the fact that I have my mobile phone with bluetooth on and discoverable.

I've followed the guide at URL.... but my computer is unable to find any Bluetooth devices. Whether I'm using the command line or gnome-bluetooth, I don't get any results. If I plug in a cheap USB adapter, I'm able to connect and use the devices.My computer is a HP ProBook 4330s running Debian Jessie. And as far as I can tell the Bluetooth adapter is a Ralink rt3592 combination Wi-Fi and Bluetooth PCI card. The Wi-Fi works fine, but when i try to connect to a Bluetooth device, I get no search results.

I am trying to get two way serial communications going between a Windows XP system and a Linux system (RHEL 5).I have /sbin/agetty -L 9600 ttyS0
in /etc/inittab. I am using a generic USB to serial adaptor on Windows (Unitek) and a null modem cable. I have putty configured for 9600 baud, 8 bits, no parity, one stop bit, no flow control.I get the login prompt from agetty in the putty window but input does not work; I see weird characters in the putty screen. I can echo output into the device from windows and see it, but
cat < /dev/ttyS0. just prints out weird characters from what I type.

I'm looking for a tool similar to synctoy in linux. For those who dont know what synctoy does is... its a simple syncing application that allows you to copy your data between multiple hard drives and keeps all copies in sync with the latest data. I'm specifically looking for KDE based tool if KDE based is not available then my second preference will be for gtk based app.

I'm using Ubuntu 10.04 and am trying to use it to recover data from a failed External HDD (NTFS).
The drive failed with an accompanying smell of electric burning and subsequently was not recognised by Windows. It would recognice the enclosure, but told me that the drive had to be reformatted.
I removed the drive from the external enclosure and hooked it up to my PC with a power cable and USB to SATA connector. I can mount the drive in Ubuntu (eventually) and I've learned enough about BASH to navigate through the files on the drive.
Those that I can access I am able to copy across to my internal drive (VERY slowly, but it does do it) but a lot of the directories show up with an Input/output Error when I run the ls -l command.
Is there any way for me to be able to access these files or to recover them? Should I be trying a different technique rather than just attempting to access and copy the files?

I have an Aspire One with Linux operating system.
I have an external hard drive that I want to save data to from my Aspire One however when I try I get a message that the external hard drive is full.
I know it isn't full and when I use the external hard drive on my other pc with Window 7 it is fine.
I am assuming my problem is something to do with the ACER Aspire One

I dont know if this is the right forum, But I try to find a solution, I want to intercept data from/to serial port without disrupting the software that manages the serial port, (I would like to save the data to a file or sent into a socket) I searched somes modules and programs (linspy, ttysniff, interceptty, maxty ...), A bit complicated (There are some diff. between kernel 2.4 and 2.6), So I'd like to change the serial port driver to intercept the "read" and "write " and do what I want with the data, I'd like to know what do you think about
