I have one of these devices and we're trying to add on our server however we have come across a problem that i see you've dealt with in the past. We receive the following data from the device:
Packet from device: 2424 0057 59772033844029 AA00 0001000051A70000000F002000003133323133372E3030302C412C313031382E323739332C4E2C30363132362E343036312C572C302E30302C3331302E39382C32333035313264530D0A
however we are uncertain as to what does the AA00 relate too at this point. We would be thankful for any help that you can give.
