    Default Sms based device switching

    Hello Everyone,
    I am making a device which can switch all home appliences, by sending an SMS through any GSM mobile to another GSM mobile interfaced to a microcontroller. This microcontroller decodes the sms received and accordingy switches the appliences.
    I am using the NOKIA 3310 and interfacing it with M-BUS to the PC COM port. But how can i see the coded frame which is generated when an sms is being received by this mobile.
    Can anyone help me?

    Nokia 3310 works only in PDU mode. This is a rather difficult to encode/decode.
    I suggest you to find out a phone that uses also text mode.
    Siemens TC35J is the best gsm modem you can find for your application. Search on ebay for second hand. If you have a phone with text mode function I will be more than happy to help you.

    Interfacing a phone that use PDU format to a PC is possible and is already been done.
    I think you should use the Fbus and not the Mbus.

    Visit the links given below they should help you to find the best way to go.

    wishing you good luck
