/Projects/GSM controller v2

TwoWay Thing (GSM controller v2) is a device that allows you to control appliances using SMS messages. There are also 4 inputs for connecting sensors so the device will send an alarm SMS or even call you to report an alarm condition. The device draws very little current and is being powered by phone’s battery which is a great thing. Nokia should be constantly charged or supplied with some sort of external power for long term operation.
TwoWay Thing has been successfully tested on:

- Nokia 7110 (19200 bps, 8 MHz crystal for PIC16F628A)
- Nokia 6210 (9600 bps, 4 MHz crystal for PIC16F628A)
- Nokia 6310i (9600 bps, 8 MHz crystal for PIC16F628A)

It should work on all DLR-3P Nokia phones with internal AT modem. These should work: 62xx, 63xx, 6210, 7110... Cable used for this device is DLR-3P cable made by www.atrox.at and it’s embedded on the same PCB with the GMS Controller v3.
Details about functionality of the device are in a word doc document among files for download.

Nisi ni svestan koliko sam ti zahvalan za sve ove ideje i nemilosrdnu podrsku...! Dozivecu valjda i taj dan da ti stegnem ruku i kazem ti "Svaka ti cast prijatelju"...! :-) Mislim da me mob zeza, cim mu stavim samo masu i vcc (pinove 9 i 4), on iskljuci mrezu...?! Ne shvatam koliko to ima smisla....Koliko sam skontao led sa '84 treba jednom da blinkne i da se ugasi i to je to, a led sa '628 treba da trepce u zavisnosti sta u tom trenu radi...?! A kako treba da se ponasaju led diode kada mob nije prikace

16F84 sluzi samo da prebaci Nokiju u "data rezim" i da joj omoguci FBUS (seriski port). 16F628 preko UART-a (seriske komunikacije) komunicira sa Nokijom. To ti je cijeli koncept. Mozes probati uredjaj sa samo 16F84 na plocici da vidis da li on odradi svoj posao kako treba. On samo treba da blinkne LED-icu i to je to.

Izvinjavam se na glupom pitanju, nisam ni obratio paznju cemu sluzi ta zenerica, ali to je jedina komponenta gde sam odstupio...Nego, postoji li neki nacin da saznam odvojeno koji chip vrsi normalno svoju funkciju...? Koliko sam shvatio da 628 ne moze nista bez 84-vorke, ili mozda gresim...?

Zener dioda nebi trebala da ti smeta... Ona LED na plocici koja je pored PIC16F84 bi trebala samo da blinkne jednom kada utaknes konektor u Nokia telefon i to je to. Ako svijetli konstantno - nesto nije OK. Pogledaj vrijednosti otpornika koji se spajaju na konektor od Nokije (taj dio sheme), ako tu nesto zeznes, Nokia nece uci u "Data mode".

Ma plocice me najvise ubijaju u pojam, to jest njihov kvalitet...Moguce da me tu nesto zeza.....A da li je moguce da me zeza zener dioda, jer sam stavio od 5.1 volt a ne od 5 ili manje...? Cisto da otklonim sumnje...?

Vjerovatno si nesto zeznuo prilikom spajanja. Pregledaj SVE spojeve, od konektora Nokie prema PCB-u od uredjaja. Garant si nesto naopako napravio :)

Ja imam nekoliko problema, prvi je sto izgubim signal operatera na mob-u kad prikacim uredjaj na mob i to samo zbog VCC pina, to jest pina broj 4 na mob-u, koji kada otkacim, imam signal...? Led dioda mi konstantno svetli i sa i bez uredjaja. Koristim nokiju 6210, oba mcu-a su sa 4mhz rez. 16F84 je prog. sa dlr2_4mhz.hex a 16F628 je prog. sa whereis_7110_6210.hex, imam kredita i precizno sam propratio postupak programiranja...Sta mi je za ciniti...?!?!

@Trax: Thanks! Sensor 3 is now working after sending those commands.

@ag12345: If everything else works, then try sending the "Z.0" command first. After that you need to enable sensors you want to trigger with "M" command. To enable all sensors send command: "M.ABCD.SSSS" - this will enable all to SMS sending. The "SSSS" part is: S=SMS, or C=CALL.

Hi Trax, I made this controller. everything works fine except for sensor 3. the controller does not sense anything when i connect it to the ground. id there a command that I should send. please also explain what the "M." is? thanks
