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.
