wireless networking - How to set up a Windows 7 laptop as a bluetooth access point?


I have a laptop with Windows 7 and with a good bluetooth interface, and with a very bad (and overloaded) wifi device.


My laptop is connected to the network through a simple, IP-based home network cable. This is what I want to share with bluetooth to other, bluetooth capable devices (mobile phones, other laptops, etc).


Thus, what I want, that other devices could use the network of my Windows 7 laptop, using it as a bluetooth access point.


Is it somehow possible? My bluetooth is pretty good configured (I can move files, I can connect to bluetooth networks, etc), but I can't see any option to make a bluetooth network access point.


What I essentially want, is similar to the netsh start wlan hostednetwork trick in the case of wifi, but this time with bluetooth. Of course, any gui-based or command line solution, even with non-standard software would be okay.


Is it somehow possible?


What I don't want:



  • I don't want to use wifi. Answers suggesting to use wifi are unacceptable.

  • I don't want to connect my Windows 7 laptop to a bluetooth "access point", I want my Windows 7 laptop to be the "access point". Thus, questions suggesting to connect my laptop as a client device to a bluetooth network, are also not acceptable.



Answer



The reason you do not succeed with creating a Personal area network over Bluetooth is because you are using the Microsoft Bluetooth stack. Using this stack, it is not possible to use Internet Connection Sharing (ICS). This was possible in older versions of Windows, but is no longer the case.


I quote from one analysis of the problem :



The problem isn't a new one (introduced in vista and still present in windows 7) - instead, the problem already existed in windows xp!


The Microsoft Bluetooth stack does not treat a bluetooth adapter like a LAN adapter. Period.


It is, however, a matter of the vendor supplied bluetooth software (as an alternative to just using the Microsoft stack).


So when I used Windows XP (and windows 2000, by the way) I could use the bluetooth software provided by AVM (vendor of Bluefritz USB) - which gave me a PAN connection and a bluetooth connection treated just like any other network adapter! Thus enabling ICS and/or bridging my LAN an my bluetooth adapters!


Since the only available AVM drivers, however, dropped PAN support in their vista drivers and tell you to switch to Microsoft Bluetooth (on the fly) if you would like to use the PAN profile, you are left with the Microsoft stack which doesn't support ICS and/or bridging with bluetooth connections! And this has already been this way in Windows XP!


I can still use the AVM bluetooth software in windows 7, but if I want to use a PAN connection, I now MUST switch the bluetooth stack on the fly (from AVM to Microsoft)! And voilà - no more ICS in that PAN connection!


But to all other people who may have issues with Internet connection sharing over bluetooth (be it since Vista, Windows 7 or whatever):


There is hope.


Third-party software DOES enable you to have ICS via Bluetooth!!


I tested several Bluetooth stacks:



  1. Toshiba BT stack

  2. Bluesoleil by IVT

  3. Widcomm/Broadcomm


In each case, I had ICS working via Bluetooth!



Instructions on using the BlueSoleil software for establishing WiFi-over-Bluetooth can be found in the article Sharing Internet Access using Bluetooth device. I have not tested them, since I don't have the required environment, but they seem mostly logical.


You may get the BlueSoleil stack from here. This is a demo version that limits file transfers to 5 MB per file, which is fine for your purpose.


Follow the instructions as best as you can. They were obviously not written for Windows 7, and the writer was not English, but the many screenshots should help where the text is unclear. However, not having tested the details, I cannot guarantee that this will work.

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...

linux - Extract/save a mail attachment using bash

Using normal bash tools (ie, built-ins or commonly-available command-line tools), is it possible, and how to extract/save attachments on emails? For example, say I have a nightly report which arrives via email but is a zip archive of several log files. I want to save all those zips into a backup directory. How would I accomplish that? Answer If you're aiming for portability, beware that there are several different versions of mail(1) and mailx(1) . There's a POSIX mailx command, but with very few requirements. And none of the implementations I have seem to parse attachments anyway. You might have the mpack package . Its munpack command saves all parts of a MIME message into separate files, then all you have to do is save the interesting parts and clean up the rest. There's also metamail . An equivalent of munpack is metamail -wy .

ubuntu - Why does my USB hdd returns SG_IO: bad/missing sense data?

I am able to boot and run commands from external USB hdd; the message in question appears for about 45 seconds then booting continues. GRUB2 is installed on internal HDD. When choosing to boot directly to /dev/sdb the message doesn't appear, however boot time is about the same as booting to internal HDD. /dev/sdb: Timing cached reads: 1018 MB in 2.00 seconds = 508.97 MB/sec Timing buffered disk reads: 80 MB in 3.03 seconds = 26.37 MB/sec pfeiffep@de:~$ sudo hdparm -i /dev/sdb /dev/sdb: SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 10 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 HDIO_GET_IDENTITY failed: Invalid argument Gparted correctly identifies the drive as SAMSUNG MP0402H. Any ideas how to remedy the HDIO & SG_IO messages?

Desktop reboots itself on sleep or hibernate

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot. Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware. Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work? More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influe...
