 Bigger Bigger  Smaller Smaller  Reset Reset

Hi,

I have a SIM300 GSM/GPRS module and i made the following steps to interface with Arduino UNO:
1) Connect TX pin of SIM300 to PIN6 on Arduino
2) Connect RX pin of SIM300 to PIN7 on Arduino
3) Connect Ground of Arduino with Ground of Sim300.

I am using the following code where NewSoftSerial.h is replaced by SoftwareSerial.h:
http://ks-gsm.svn.sourceforge.net/viewvc/ks-gsm/ksgsm.pde?revision=3

Below is the datasheet of SIM300:

Nothing is happening when i send AT command from Arduino, please guide me on what needs to be done.

Thanks,
Anil

This section of the forum is for discussing NEW hardware development. It does not sound like you are creating new hardware. So, this post does not belong here. You'll get more answers posting in the right place.
