When a Pocket Buddy is indoors, the device is unable to obtain sufficient GPS (location) 'fix', and so the location sent to the platform may be inaccurate. Although the device will have a strong GPRS (mobile data) fix, it needs to have a valid GPS fix to send accurate reports, which can only be acquired when the unit is outside. This is because when indoors, walls attenuate the signal from GPS satellites.
The top LED (light) shows whether the device has a GSM fix and has a red light. The bottom LED shows if the unit has a GPS fix and has a blue light.
- The LEDs will flash every two seconds to signify that they are trying to acquire a GSM/GPS fix.
- The LEDs will flash every five seconds to signify that they have a GSM/GPS fix.
- If the LEDs are constantly on, it means it can not acquire an accurate GPS fix and that the device may be faulty.
