is it ok if i connect SIM300CZ gsm module digital and analog ground with each other in my circuit design ???
We (me and my friend) have designed a circuit that includes SIM548C gsm module. This circuit is powered by 4.24 V DC. Actually this voltage is acquired by using LM2576 regulator IC and input of it is 12V DC. So while 12V dc is available, my purpose is served. But in absence of 12V, i have nothing to do. So, i want to (...)
Hi, I have a circuit diagram of SIM300C but it is in chinese. the main COM should be connected to the MAX232-UART port of the micro. basically, it is a RS232-gsm module. the main connector of SIM300 is connected to your device. the other connector is when you must configure the output/select the gsm band to be used.

Hi sujan, check the recieving part of your it the same you are using or not. I had faced the same problem but i dit it atlast. Better you add your circuit and program till then nobody will come to know where you are facing the Problem.
I bought Simcom SIM V_7.03 gsm module, Can i get the datasheet for it, with external components too. I am not able to understand purpose of additional circuit. plz acknowledge me as soon as possible.....
@manjunatha it depends what is the module, what is your micro-controller, and how are you interfacing the rest of peripherals such as LCD etc and what you need to get out of this setup.. so u cant ask for correct code like that. secondly you should share your schematics and your circuit here and we can try to help out with the problems (...)
First of all you need to post the circuit diagram that you are working on .....Basically Atmel processor that you are using have Seial Port interface that you need to connect to Max232 Ic and then connect the DB9 Serail port connector to the Serial Connector of SIM900 board connector.... Now to program the atmel you need atmel programmer for the c

I want it to be as cheap as possible. Here are some of my questions: 1. Is there anything (already made board) that I can buy and program it? I (...)
I am not into good cheap gsm modules, but if it has to work under low signal conditions, make sure you have a good antenna and use it properly. Frequently the design is almost finished and then somebody says: "We need an antenna, where do we leave it, we don't have space?" Frequently the antenna is put at an inconvenient place and doesn't perfo
