GPS Assist URLs can be resolved.
6.12 Motion Logs (1hz vs 5hz GPS Sample Rate)
Since there is a difference in the GPS update rate (1Hz vs. 5Hz) between the LMU8 and EdgeCore
products, there is an impact on the sampling in some of the pre-defined motion logs.
On an EdgeCore platform the Short Motion Log types 0-4 samples at a fixed interval of 200mS
while on the LMU 8-Bit the sample interval is 250mS. This causes the motion log buffer to fill up
faster.
The Short Motion Logs Types are defined on Calamp’s wiki site:

6.14 Version String in ID Reports
The EdgeCore platform sends and displays the version string in a different format.
ID Reports:
The firmware version of the LMU-1300, can be obtained from the LMDirect ID Report, Extension
String field. In that field, there is a new Key-Value pair in the “LMUAPP” extension string. See the
definition below.
