Hello all,
I'm developing a board using a LPC2129.
This board must comunicate with a PDA using a bluetooth channel.
I've never used bluetooth before so I have many doubts.
I was thinking on using the LPC UART and convert that to bluetooth.
Is this possible? How? Any recomendations?
Is there any special requirement on the PDA side?
I need some ideias to point me to the right direction.
Any comments will be apreciated.
Best regards.
Rui Gonlves.
LPC board with bluetooth

Hi,
It all depends on the Bluetooth module, like this one
http://tw.f4.page.bid.yahoo.com/tw/auction/d23041293
this module can let you use UART to connect your board to, however
the baud rate is only 4800 bits per second. and on the PC side, it
will show up as a virtual com port, so that you can use a com port
program to transfer data.
But if you want your Bluetooth to talk to your PDA using another
service (like File Transfer, Audio ......), then you need to find a
Bluetooth module which already has the service software (or in
Bluetooth's term - Profile) implemented in the module or you need
such software on ARM board (if you can't find such software, you need
to write it, but it is not an easy task).

You can see information LPC2104 Color LCD Game
with Bluetooth from http://www.embeddedartists.com/
This board used Bluetooth based on NXP's (Philips) BGB203-S06.

The Embedded Artists board is a fun board to start with.
For a small price it gives you a quick start with bluetooth and you get
a great LCD with it too.
The only limitation I have is the lpc2104 (128 kB Flash, 16 kB RAM).
The Flash size is enough (for my app) but I like to do debugging from
RAM and the 16 kB is just not enough to load and debug even part of the
application.
To be able to debug at least the UI/LCD development I made some
modifications: I tied the reset line of the LPC2104 low, this places all
pins in tri-state mode, and connected the four lines of the LCD to my
lpc2106 board. See the august 15 (ald latests ...) entry on
http://www.myvoice.nl/electronics/
for some more information and pictures.
Using this board for Bluetooth development you may enter some more
limitations.
The BGB203 does have UART, I2C, USB, PCM and JTAG connections but the
only connection on the EmbeddedArtists board is the UART.
Not that this is a big problem since NXP seems to share only the UART
protocol - I could not find any information on the other interfaces
[:-s]
The board is great, I ported an 6502 emulator that's fed with the
Usurpator chess program (a bit slow but it works) and am now using the
second board as user interface and bluetooth gateway to the PC.
Watch out using the BGB203 module: I found that making a connection with
my Nokia 9300 does not work that well, as soon as I disconnect from the
9300 it reboots (a complete reboot of the full Symbian system ...)
