Hi,
Thanks Mike pour your reply.

That's why I said "it's weird that it does not work for me".

For BoilerPlate, I installed it on the shimmer on Windows using the
software provided on the Shimmer-research site web. With ShimmerConnect, I
tested on Windwos then on Linux (FYI: on Linux, I use mono to run
ShimmerConnect app). It works in both OS.
And I talked about BoilerPlate and ShimmerConnect because I can make this
work on bluetooth connection but the simple Bluetooth test does not work.
There seems to be nothing special in bluetooth configuration on
ShimmerConnect than on Bluetooth test, then why the former works and the
latter does not ?!

Yes, I got this on my machine when running rfcomm command:
rfcomm0: 4C:ED:DE:70:58:8B -> 00:06:66:42:20:81 channel 1 connected

Yes, also done that. What I get on the screen of minicom is:
========================
Welcome to minicom 2.5
OPTIONS: I18n
Compiled on May 2 2011, 10:05:24.
Port /dev/rfcomm0
Press CTRL-A Z for help on special keys
========================
and the cursor on the screen keeps blinking, like, forerver :D
When I click the power button on the shimmer, on minicom screen, a string
of "$$$" appears.

Yeah, I said that to me too, except that I can't make the Bluetooth thing
work for me so I was a bit desperate :p.
Beside, I tried to track the Bluetooth app, and it seems that the app
failed to establish the connection to my computer. The green led never wake
up (i.e. set on) as it is indicated in the code of Bluetooth example
########################
async event void Bluetooth.connectionMade(uint8_t status) {
call Leds.led2On();
call activityTimer.startPeriodic(1000);
}
########################
| Besides, the source code for ShimmerConnect is available on request
from i...@shimmer-research.com, so you can easily go poking through it to
confirm this for yourself.
Yeah, maybe I should try this. Thanks for the information.

What I meant is that with ShimmerConnect, the collected data can be stored
in a csv file and/or visualized on the ShimmerConnect GUI. What I need is
to get those data in realtime to feed another program of mine. Getting data
from the csv file is not a solution.

Thank you Mike.
I'll write the shimmer-research for the code source of ShimmerConnect, and
in the mean time mine a litle deeper in the tinyos documentation to see if
I miss something...
Have a nice day,
Ha.
