Hello,
My mobile phone (Nokia 6320i) being able to send/get AT commands, I would like to interface it to my Arduino. 
For exemple to send SMS!
It seems to be possible, regarding this post: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1267318675/2. However, the poster did not say what kind of cable he used/made.
Using original cables?
There exists two different ones:
- DKU 2, that I used to interface the phone with my computer to try AT commands. Specs: Nokia N60, N70, N90, N91, N93, E70, E61, E62, E60, E50, 3155i, 6680, 6681, 7600, 7700, 7710, 9300, 9500 pop-port DKU-2 (CA-53) usb cable schematic pinout diagram @ pinoutguide.com.
- DKU 5, that looks exactly the same than the former, but it seems it is in fact a "hidden" serial cable. Specs: Nokia pop-port LIKE-DKU-5 or CA-42 cable schematic pinout and wiring @ old.pinouts.ru
> With the DKU 5, it would be perfect cutting the cable, and maybe using a 3.3/5V level converter, right ? I'm not sure it is compatible with the phoe however...
> But what about the DKU 2 ? I don't think Arduino Duemilanove is able to read true USB data, although it has an USB port ?
Directly from the phone?
I found the details of the phone's connection pins here: Nokia Pop-port pinout diagram @ pinoutguide.com.
The interesting part is:
| 6 | FBus Rx/USB D+ | USB exists only in some models*. Should be connected to USB pin 3 in usb data cable. (USB DATA+) |
|---|---|---|
| 7 | FBus Tx/USB D- | USB exists only in some models*. Should be connected to USB pin 2 in usb data cable. (USB DATA-) |
> Would it be possible to connect those two Rx/Tx pins to the ones of the Arduino, again using maybe a 3.3/5V level converter ?
If anyone can lighten me up, I would be very grateful.
Thank you,
Klaus : )
