implementing HandsFree profile
at
Windows CE Networking Team WebLog I found an interesant
post about how to implement
bluetooth HandsFree profile. By Googling "handsfree profiles on .net compact framework", trying to extend search, I saw that
Peter Foot's site also talk about it, in addition, Peter shares an
assembly that allows you to use this profile using audio gateway for your PPC application.
Broadcom WIDCOM SDK now free!
Broadcom now released the
Bluetooth SDK for free. Only need to register and they will send you an email with the link. There are the libraries and some samples but not source. I think this is a great new!!!
interesting tools
I found an interesting
bluetooth tool site called
BlueHoc: Bluetooth Performance Evaluation Tool . This one, is one of the most bluetooth sites I want to show in this blog. This site is under
SourceForge.NET, and have a lot of information pages about
bluetooth.
I encourage you to spend some minutes discovering it
my bluetooth library perspective
hi,
just finished an article about bluetooth programming on .net compact framework for spanish magazine (dotNetMania) [it would be published between July-September of current year], I developed a basic bluetooth library. I focused it to be easier development. The started class is called BthSesion. This one, allows to begin using bluetooth radio and all profiles. See this example...
BthSesion ses =
new BthSesion(
true);
this simple line allow to initialize bluetooth radio, sockets (by using BthSocket), detect all paired devices, and by passing
true by parameter, this class also has discovered all the closer bluetooth devices. If the radio was off, then it should switch it to on.
once
ses variable is set, I have information about bluetooth radio like manufacturer, bluetooth specification version, profiles availables and more;
this.txtInfo.Text =
ses.MiRadio.ToString();
the devices paired and devices discovered are stored each one at ICollections class called
BthDispositivosLista (
BthDevicesList). This class has a collection of
BthDispositivo (
BthDevice) classes. I will explain it in detail the next day.
faq's sites
Here, a faq's sites collection. Enjoy it!
ClassOfDevice discussion
I've just meet
Peter Foot's site forum, a very interesting
discussion about ClassOfDevice stats. Most of this information could be downloaded from
Bluetooth SIG web site, but here you can find the most interesting items.
enjoy it!
where to begin with bluetooth programming?
have just decided to begin with
bluetooth programming? well, there is no easy way. just begin understanding what's bluetooth specification and profiles.
see this post.
do you understand bluetooth's specificaction and which profile you need and why? so the first step is discover, pair and establish connection between bluetooth devices... let's take a look an Microsoft's Bluetooth Stack example (
Windows Embedded Source Tools for Bluetooth Technology).
don't forget that this library is only available to Microsoft Bluetooth Stack, do you know if your device supports it? look
this device list. (don't forget register before)
see how to
BluetoothRadio class method called PairedDevices shows the paired devices. this devices are hosted in registry(
HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\Device). this class also allows to set/get the radio state. this state could be
on,
off and
discoverable. the last state is a good way in order to prevent battery. it's very interesant to know what is the bluetooth specification version, the manufacturer and your device availables profiles . the next post I'll show you how to get this information in order to enhance BluetoothRadio class.
if you do need and WIDCOMM example let's go to
high-point site. unfortunaly, the WIDCOMM stack it's not free but you may download a trial assemblies. this assemblies are compiled so you only may use it. in this way is possible you don't want to developer a entire bluetooth library (
with Ms Bluetooth Stack), so you want to use it! see
Peter Foort's 32feet.net site and his library called InTheHand, see chat sample. You'll find a managed library to develop a bluetooth based applications. If you want to see examples about, look
32feet.net examples and
Lawrence Patricio blog has a lot of example based on InTheHand library. do you want to play chess through bluetooth?
bluetooth sig, the boss
bluetooth was created by
ericsson .
bluetooth was conceived to connect devices in a wireless context. if you want to know where
bluetooth's name come from, what are the origins and which companies created
sig, look this sites...
dont't forget to know how bluetooth specification works, what are bluetooth profiles used for, then decide your application scope.... do you want to develop an entire bluetooth library? or only to use it? what platform would you use?, why?
well, we talk about this the next post....
about some books...
Getting started..
For Java
Let's beginning!!
Hello!
This is just the first 'stone' of a site that tries to englobe all knowledge about bluetooth programming.
I apologize my english; I will be effort to write as well as I can.
Let's beginning!
