here i write my experiance with witilt ver 2 bluethooth wirless module and its interaction with max\jitter program.
power- the manual says 4-6volt. i used 2 3v batt, i got the red light but the bluetooth couldnt find the device. i would be happy to hear from anybody on batteries that work. and can be bought locally.(update: now it works)
i am using a 5vol 800mA wall wart taken from an old iomega zip drive i had. it works.
make sure you connect using a passkey, the passkey is default. for connection i use a cheap BT usb connector from MSI, and xp bluetooth network connection app.
hyprterminal connects just fine using the raw mode.
i had another program i wanted to work with (eyesweb.org) but has a strange habit of only working with serail devices between the range of 1-9, as my com was 10 i was out.
luckely u can change the assigned com port of the bluetooth serial in [control panel>hardware>device manager>ports>standard serial over bluetooth link (com10)> port settings>advanced>com port number] check box.
some of the lower com number are marked as “in use” but after clicking away the worning it works. my bt com is now com 5…
i connected to max\jitter using the serial object. it did not recognize the assigned port (com10) but after looking at the names he gave the port he did recognize (a=com1…d=com4) i changed the serial name to j (=com10) and got it talking.
i am still stuck here as i am getting ascii codes and need to find a clean fast way to turn it into chareters, and then write a parser that can chop the input
i manged to fry one the caps trying to connect a diffrent power supply. must have short circuted. the C1 cap just blew in my face. ho the smell of stupidness.
i went out and bought a 10uF cap and soldered it in place, the witilt works. again.
i post again after a long time, regarding a different project. and it hit me i forgot to show the result for this one.
here are 2 youtube vid’s of the accelerometer connected to max/msp/jitter over bluetooth. the first one is a bit rough, no battery and no video textures.
the rendering is done using jitter opengl capabilities. basically the patch takes the current position of the sensor and pushes previous position back, creating a segmented line, that gets various polygons attached to. on those polygons i texture video (can be live, not shown) and shaders. i can (clean) and attach the source if your a jitter user.
i would also like to thnx sparkfun for their support and connsidration. your great!
