hi guys,

i have a cellphone nokia 6610 and i want to ask how to interfacing nokia 6610 to arduino? is there only connecting the tx-rx-gnd 6110 to the arduino or use rs232 to ttl adapters?? does anyone have wiring diagram connecting nokia 6110 to arduino?

Thanks,
best regards. :smiley:

the pinout http://pinouts.ru/CellularPhones-Nokia/nokia_pop_pinout.shtml

pins 6 & 7 used for serial comm. I'd guess u need a rs232-ttl adapter.

I'm not 100% certain, but I belive the nokia understand AT-commands
From search, it looks like the phone HAS TTL-level (u check this with a multimeter)
If its RS232-level, u need an adapter or build one yourself
....
others have ttl

Check voltage at comm-pins on your nokia (the internal 'dots') to verify that they are almost TTL-level
(0V ..3.5V ?) If this is the case, you can connect directly. (add a small resistors i series with arduinos TX)

I guess softwareserial can be used. Connect common groud,
Rx to Tx, both directions.
