Please note that I have included 2 PDF manuals within this directory. The first, gps306a_b-user manual, is the actual manual that came with the device we were testing. The second, coban GPRS protocol, is NOT the manual for the device but it is for a very similar device. The reason I have included it is because it explains the gprs protocol and messages very well and is useful knowledge.

tk103-server.php is the actual server. I will explain in a tutorial how it works.

socket-client.php can be used to test the server but is not required once the server is setup and running properly.

this is a log of 3 gps data points received from the ODB gps device we were testing.
