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: http://pinouts.ru/CellularPhonesCables/nokia_dku2_cable_pinout.shtml. - DKU 5, that looks exactly the same than the former, but it seems it is in fact a "hidden" serial cable. Specs: http://pinouts.ru/CellularPhonesCables/nokia_dku-5_cable_pinout.shtml
> 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: http://pinouts.ru/CellularPhones-Nokia/nokia_pop_pinout.shtml.
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 : )
