How to interface GSM adn GPS to the LPC2148 micro controller.

sucharitha G

Hi All,

Am trying to interface GSM(UART0) and GPS(UIART1). I checked individually both modules are working perfectly by connecting to the both UARTs. When i connect to the both then my MUC unit is going to be hanged. if i swith off the GPS moduel then it is working correctly. Can any one pls help me to solve this.

    Am using 12V adapters for all modules. Is it sufficient? And plese check hte below code if you have time.

    My aim of this code is that if i messaged to the mobile no which is placed in GSM the it has to replay to that no as GPS (LT and LG) Values. for that am first initalizing the components(UARTO_init, GSM init) and then reading the message ,getting the GPS values and replying back to that no. I tested individually these 2 operations but when connecting both then it is hanging.

    I hope now my problem is clear to you.
