I am develloping in C (using Tasking compiler for C16x) a software which consist of data center ,for sending and receiving SMS per GPRS, and making distance diagnostic task. The idea of the project is to send an SMS to activate some specified task such as update eeproom, receiving data from the mobile station(with the modem), sending data from a fix station with a PC (hyperterminal) through rs232 to modem.
My formal collegue realize this task with GSM and it works, so i have to realize now a GPRS connection and sending an SMS or e.mail with the format (password;command;parameter) which activate a task on the integreted C167 Processor.
The problem is I have no idea for GPRS at the moment.
1) would you mind helping me in such a way to build this GPRS connection ?
2) How can I code the SMS-Message (command part) in order to activate a specified Task (I wrote the c - code for all tasks as functions)?
3) what is the maximum weight (in bytes ) of an SMS that can be sent using GSM/GPRS Modem MC35T ?
