-//tk102 data from Brent's device. note that data received is not always complete.
+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.
