GV300LAU Troubleshooting List 

Problem 

Possible Reason 

Solution 

After the device is 

turned on, the CEL LED 

always flashes quickly. 

The signal is too weak. The 

device isn’t registered to the 

network. 

Move the device to a place 

with good network coverage. 

Messages can’t be 

reported to the backend 

server by network. 

APN is not right. 

Ask the network operator for 

the right APN. 

The IP address or port of the 

backend server is wrong.   

Make sure the IP address for 

the backend server is an 

identified address in the 

internet. 

There is no response from 

UART when the device is 

configured by using UART. 

The port is not ready or the device 

is not powered on. 

Please check the port and the 

device to ensure they are 

working properly. 

Th

e device can’t get GPS 

fix. 

The GPS signal is weak. 

Move the device to a place 

under open sky. 

It is better to make the side 

with antenna face the sky.   

7.2.

 

Safety Info 

 

Do not disassemble the device by yourself.   

 

Do  not  put the  device  in the  overheated  or  too  humid place,  and  avoid exposure to  direct 

sunlight. Too high temperature will damage the device or even cause battery explosion.   

 

Do not use the device on the airplane or near medical equipment.
