Bluelet™ Host Protocol Stack & Profiles
Stack and Profiles Source Code
Stack and Profiles Object Code + API
Application Profiles SDK
IVT Bluelet™ is a full implementation of the Bluetooth?
host protocol stack using ANSI C. The code, which is very efficient,
reliable and small, is suitable for embedded applications as well
as desktop applications. IVT performed protocol validation using
the formal design technique, Specification Description Language
(SDL), to assure that all protocols are logically correct before
coding. Now Bluelet V6.0 is already qualified as a fully compliant
v1.2 Bluetooth protocol stack.
|
Major advantages of the IVT Bluelet™:
- Based on validated SDL model
- Library based ANSI C source Code, easy to port
to different OSs
- Support different OSs with the same core (Windows
98/ME/2000/XP, Windows CE, Linux, Nucleus, REX, COS-II, ITRON,
OSE, VxWorks, pSOS+)
- Small code size, ideal for embedded applications
- Support many different Bluetooth chipsets (Cambridge
Silicon Radio, Broadcom, Ericsson, Infineon, National Semiconductor,
Philips, ST, OKI, Silicon Wave, TI, Waveplus, Zeevo)
- Support different HCI transport layers (USB, UART,
PCMCIA, BCSP)
- BQB Qualified, compliant with latest Bluetooth
Specification
|
IVT is working closely with Bluetooth chip manufacturers
to ensure the interoperability of IVT Bluelet™ stack with Bluetooth
chips through HCI. IVT Bluelet™ is used in IVT BlueSoleil-PTS as the
reference implementation and used by many Bluetooth test houses
and manufactures to perform conformance and interoperability testing
against many different implementations. Therefore, IVT Bluelet™
can offer maximum interoperability with others.
|
IVT Bluelet™ protocol stack
system can be divided into four parts, as shown in Figure 1:
|
- The first part is the Bluelet System Module. Each
protocol registers itself in the Bluelet System Module when
it starts up. The Bluelet System Module maintains the Bluetooth
host protocols' Finite State Machine (FSM) instance table. A
Bluetooth host protocol can use this information to communicate
with other Bluetooth host protocols. This module can vary on
different platforms, as not all applications require all of
these protocols.
- The second part is the Bluelet Common Function Library
Module. This module contains the common code used by the
FSM of each protocol, such as the code for timer management
and inter-process communications. It also contains all platform-dependent
code in the system. When there are multiple requests from different
Bluetooth host protocols' FSM instances for common resources,
it provides scheduling for these requests.
- The third part is the Bluelet Protocol Modules for
each protocol in the Bluetooth host protocol stack. Each protocol
module is implemented using ANSI C and can be easily ported
to any platform without modification. It implements states,
events and FSM matrices for each event stimulus in each state.
- The fourth part is the Bluelet User Interface (UI).
This part is a system-dependent module. Users can develop their
own UI to meet specific requirements.

Based on the Bluelet™ Basic Host Protocol Stack, IVT also developed
full range of Bluetooth application profiles which can be provided
in source code, object code or SDK form for product manufacturers
to develop their particular Bluetooth product such as cameras,
printers, PDAs, CDAM phones, smart phones, and so on.
|
IVT Bluelet™ provides the following
Bluetooth profiles:
|
| Serial Port Profile |
| The scenario covered by this profile deals with
legacy applications using Bluetooth as a cable replacement,
through a virtual serial port. Any legacy application, such
as Hyperterminal and Direct Cable Connection, may run on either
Data Circuit Endpoint (DCE) or Data Terminal Endpoint (DTE),
using the virtual serial port as if there were a real serial
cable connecting the two devices (with RS232 control signalling).
|
| Features: |
* Support applications using conventional physical
serial port
* Independent of DTE-DCE or DTE-DTE relationships between devices
* Establish and release emulated serial cable connection
* Transfer user's data, modem control signals and port configuration
commands |
| LAN Access Profile |
| Aided by LAP (LAN Access Point) of Bluetooth,
DT (Data Terminal) is able to access the services of a LAN.
Once connected to LAP, the DT will operate as if it were connected
to the LAN via dial-up networking. In the case that Multiple
DTs use one LAP as a wireless means, connecting to a Local Area
Network (LAN), the DTs can also communicate with each other
via the LAP. As a special case, two Bluetooth devices can form
a single connection with each other. This scenario is similar
to a direct cable connection commonly used to connect two PCs.
In this scenario, one of the devices will take the role of a
LAP, the other will be a DT. |
| Features: |
* Support any legacy application using PPP
* Establish PPP link between DTs
* Adopt some appropriate PPP authentication mechanism (e.g.
CHAP)
* Transfer data packets and port configuration commands.
* Indicate PPP link losses
* Release PPP link from either DT or LAP |
| Dial-up Networking Profile |
| IVT implements Dial-up GW (Gateway) and DT (Data
Terminal), allowing a DT access to the public networks through
GW using PPP. Users can use a cellular phone or modem as a wireless
modem for connecting to a dial-up Internet access server, or
use other dial-up services to receive data calls. |
| Features: |
* Scalable according to different AT command sets
* Support any legacy application using PPP
* Establish or release PPP link from either DT or GW
* Transfer PPP packets, modem control signals and AT commands
between GW and DT
* Enable GW automatically to monitoring status after DT or GW
releases the PPP connection
* Indicate PPP link loss |
| Headset Profile(Headset Control and Audio Gateway
Control) |
| The headset can be wirelessly connected for the
purposes of acting as the device's audio input and output mechanism,
providing full duplex audio. The headset increases the user
mobility while maintaining call privacy. |

| Cordless Telephony Profile & Intercom Profile |
| With these two Profiles, a cellular phone can
be used as a cordless phone or a walkie-talkie when possible.
In Cordless Phone Profile, the call is sent or received through
a voice gateway which is connected to a fixed net. In Intercom
Profile, voice connection is established directly between two
cellular phones. |
