Windows 8 and Bluetooth module installation and reconnection

clock Juni 24, 2013 01:06 by author Administrator

First click “WIN+Q” to perform a search in the Settings of Windows 8. We put “Add Device” and already have access to the option “Add Bluetooth device”

or search for “bluetooth”


The Serial over Bluetooth-Feature must be add manually on the properties dialog of

the paired device (I used this one. ID = 1234 and this one as Bluetooth-USB-Adapter).

this is also a good info on HC-06 Bluetooth module (telling how to use and add).

How to reconnect ( WIN8) no. is not a Headset! (or here or partially this)


First click “WIN+Q” to perform a search in the Settings of Windows 8. We put “Add Device” and already have access to the option “Add Bluetooth device”





This is not correct (MS removed the reconnect feature – on SPP-profile silently! That is the reason!):

The PROBLEM with Bluetooth in Windows 7 is that there is no “Reconnect” button for the Bluetooth devices, so simple items such as a Bluetooth Mouse must be removed and paired again to use it again. Such a hassle! Does this BUG still exist in Windows 8?

By the way, Ubuntu 12.10 has absolutely NO PROBLEM reconnecting a Bluetooth device after it has been used elsewhere, so this is definitely a shortcoming of Windows OS.


Reconnect is done automaticly by choosing the right outputport in blinking state.

By typeing “AT” once on BT-Serial the device entered in “connected” state by setting led red on.

It seems to be that an manual “Reconnect” is not necessary!

Tip: Buy always these things at least  twice, my first module was “burned out”  after the first tries ….

The second one is running as expected!




Using TeraTerm or Putty for testing.

Minimal HTTP-Server

clock Juni 15, 2013 23:37 by author Administrator

While you can write your own HTTP server using normal TCP/IP (it's relatively simple), it is easier to use HttpListener, which takes advantage of the HTTP.SYS functionality added in Windows XP SP2.

However, HTTP.SYS adds the concept of URL ACLs. This is partly because HTTP.SYS allows you to bind to sub-namespaces on port 80. Using TCP/IP directly avoids this requirement, but means that you can't bind to a port that's already in use.

On Windows XP, you can use the HttpCfg.exe program to set up a URL ACL granting your user account the right to bind to a particular URL. It's in the Platform SDK samples.

On Windows Vista, HTTPCFG is still supported, but the functionality has been absorbed into NETSH:

netsh http show urlacl

...will show a list of existing URL ACLs. The ACLs are expressed in SDDL.

netsh http add urlacl url=http://+:80/MyUri user=DOMAIN\User listen=yes

...will configure the MyURI namespace so that DOMAIN\User can listen to requests.

For example, instead of "http://*:9669/" you can write "http://localhost:9669/". This works fine with HttpListener and doesn't require administrative privileges (at least on Windows 7).

httpcfg set urlacl /u http://+:8081/YourService /a "O:DUG:DUD:(A;;GX;;;IU)"
