    Hi,

    I have done a quick searching on the web. It seems the modem sim900 has serial port and uses AT commands. So if MSP430FG439 has serial port ( I would say yes), there would not be problems to interface both devices. You only have to use the serial port of the uC to send the AT commands to the modem and to receive the response from it, and then, interact with these data how corresponds.

    Best regards.

    The way to answer that question is to study the documentation (datasheets, etc) for both the sim900 and the MSP430fg439:  that will tell you what facilities each one requires, and what facilities each one provides - if the two match, then the devices are, by definition,  compatible.

    So why did you say sim900, then?

    AFAIK, TI do not make modems/modules; they make chipsets for use by modem/module manufacturers - but they do not make the modems/modules themselves:

    I think Enfora modems/modules use TI chipsets: http://www.enfora.com/index.cgi?PageLanding:CONTENT_ID=53&User:LANGUAGE=en

    Anyhow, regardless of who makes the modem/module, the task of interfacing it to an msp430fg439 (or any other microcontroller, for that matter) remains the same - as previously stated.
