Basically, this is a GPS receiver with bluetooth module that allows one to pair a Mobile/PDA/PC and get the GPS data in NMEA format. It has a logger function also that stores the GPS data in its internal flash memory at regular (configurable) intervals. The storage is huge and it has never ran out of memory even with 10-12 hours of logging (5s interval).
Issues that i have found.
- When downloading the GPS data from the device on the same day, the last portion of the data would not come out. If I log some seconds on next day and then try again, I would get the whole data for the previous day without any issue.
- If I switch off the device during some breaks in the trip, the logging gets screwed up. The continuety is lost sometimes.
- While on a trip, connect the device to the car adapter and never switch off till the end of the trip.
- 5 second logging seems to be reliable and anything less can cause issue for long trips.
- Wait for a day and log a few seconds in open sky (GPS lock) and they download the data for previous trip.
