b.Host with BLE beacon

Cannot connect platform
1）If power cables are wired correctly? Pay attention to not
connect them to controlling cables of vehicle.
2）If SIM card is installed correctly? Please refer to the
installation instructions.
3）Check status of LED indicators. If device is OK,12 red and
blue LED will intermittently and slowly flick.
4）Inquiry parameters of device via commands and check
replied parameters.
9. Troubleshooting
Type Use
Device is never online on the position server when installed at
the first time. Please check device:
Offline status
1）call SIM card of device and check if you can hear connecting
ring.
2）Check if vehicle is in the area where there is no GSM or LTE
CAT M1/NB1 signal.
3）Check if one device or all devices are offline in the area . If all
devices are offline, you should ask operator If network is OK.
4）Check if SIM card has enough balance.
5）If device becomes offline on the last day of one month, please
check data transferring is closed or not.
6）Inquiry parameters of device via commands and check
replied parameters
First check if LED indicators are OK, if cannot check them, you
can check SIM card following next steps:
No positioned
1）If the vehicle is in the place where there is no GPS signal.
2）The upside of device should be installed with face toward
the sky.
3）The GSM & LTE CAT M1/NB1 and GPS signal may be
weakened if device is installed in the place with electromagnetic
wave absorption material(such as metal blocks), special attention
should be paid if there is metal thermal insulation layer or heating
layer on the front windshield, so that the position accuracy will
decline, and the severe ones will not be positioned.
If the GPS is active, but device cannot be positioned for long
time, please check device:
