Posted at 2014-02-14 by @gfwilliams This is awesome - thanks! I've got a T68i kicking around - I wonder if that'll handle it. Come to think of it - it has bluetooth I think. I wonder if the bluetooth module would connect to it (as a host) and would still be able to send the commands? |

Posted at 2014-02-14 by BogdanG T68i has the same DCU-11 interface as the T630 (uart interface with unfriendly connector, some people managed to solder 3 cables /rx, tx, gnd/ directly to the phone). I bought USB to DCU-11 cable and simply cut off the USB part and soldered serial cables to the plug). |

Posted at 2014-02-14 by BogdanG It seems that bluetooth can be used for accessing GSM modem: Bogdan |

Posted at 2014-02-14 by BogdanG Try to use: to see if '1' value is available. "1" means that PDU mode can be disabled. The default is usually '0' |

Hi,
Some time ago (before espruino 1v30) I tried to port my Nokia based GSM temperature monitoring system to espruino. Just for fun because my linux based solution worked fine.
Unfortunately it was a failure because I was not able to implement the Nokia's FBUS protocol on 8KB STM32VLDiscovery board. I simply ran out of memory...
The other day I bought an old Sony Ericcsson T630 which has nice serial interface based on AT commands. Here you can find similar models (they may have slightly more difficult SMS encoding scheme so be warned!). These phones are really cheap - a couple of euros.

Here you can see an example how easy you can send an SMS:
The code above is really rough (it's not an example of good javascript style, neither good programming). It's purpose is to show the idea of using cellphone with espruino.
