Hi I want to connect GSM modem to the STRE912 board I configured the uart which can recieve interrupt from modem I am using uart 0 for connecting the modem and uart 2 to debug the application but the modem is giveing timeout errorthe processor is str912Fw44 I used both ways ( by RS232 as well as TTL level to connect to the modem) but it gives timeout error
Your Olimex board has JTAG - use it!
www.olimex.com/.../str-e912.html
IF you don't have a JTAG adaptor, debug you code in the Keil Simulator - direct the USART IO to a COM port, and connect the modem to that COM port
Have you actually tested the command sequence you are trying to use - eg, by sending it manually from hyperterminal, and observing the modem's responses...?
eg, what is AT+CMIS supposed to do...?
dear neil
I solved the problem it was due to not properbaud rate thanks for your valuable time and reply now I have to convert same code to RTX kernel
thanks
