Educational SIM548c Tracking Project - Basic questions to get me started.

[Mark10]

Hello all,

I am about to begin a prototype style asset tracking project, after searching around I have available a SIM548c unit / antennas / evaluation board etc.. I am about to order the items. pic below is an idea of the module.



I have some experience of using programming etc, and can pick it up quite fast.
What I require is a Basic understanding of the tracking process.

Apologies in advance if I am incorrect in any of the following - I am at beginning of a learning curve!


The project is to demonstrate the following:

1) Tracking unit to respond to SMS commands sent from a mobile phone.
2) Position of tracking unit to be sent back via text showing LAT/LONG co-ordinates + http web link to Google maps that shows position of device. (Also returning battery status information)
3) GEO Fencing

As far as I am aware ?

1) I can use the SIM548c module as a standalone GPS tracking device by inserting a PAYG SIM card and providing a battery power source.
2)A pre set program stored onto the SIM548c will then respond to SMS message commands sent to it from a mobile device.
3) The SIM548c module will then return requested information to a mobile phone device over the mobile network (as per SIM card).


I do not yet fully understand

1) How to program the SIM548c at commands?- does anyone have a simple tracking file program, that I can learn from and add to?
2) I assume the program is sent via HyperTerminal or other?

Thanks in advance! :smile:

hello mark,

you can use hyperterminal, for sending AT commands but not for programming. but c++ and the other programming languages have interfaces for AT commands.

does anyone know how to send AT commands to SIM548C via SMS? I am making a project and any help will be much appreciated.

thank you in advance,
