I am a senior at Rochester Institute of Technology and I need some information on linking up a cell phone to a microcontroller for my robotics project. The idea is to connect a CDMA cell phone (Verizon or Sprint) to an HCS12 microcontroller via a serial link (RS232). Hopefully, this will allow me to send and receive serial data from the microcontroller remotely. After reading through the site and the C++ code for weather BBS project, I have this question. After connecting to the cell phone and having the microcontroller issue the appropriate AT command to answer the call, how easy/difficult is it to send/receive serial data? Is it as simple as writing to the serial port of the microcontroller (and the cell phone connected to the serial port sends each individual characters to the other end, like a direct link through hyperterminal)? Or is it more involved with more AT commands and encoding/decoding data streams from/to the cell phone? I just want to know how involved this might be, whether it is worth it, or maybe I should just get a pair of inexpensive wireless modems (like 433MHz Long Range Radio from HAC). It would be really nice to have the unlimited range with the cell phone as the modem.
Thanks.
Thanks.
