Trouble 

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. 

The device cannot be 
powered off. 

The function of power key is 
disabled by 

AT+GTFKS

Enable the function of power 
key by

The device cannot be powered 
off if charger is connected or 
external battery is used. 

Disconnect charger or external 
battery and try again. 

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. 

The 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.
