What to do if there is no response from UART when configuring Queclink GPS?
If there is no response from UART when configuring your Queclink GPS device, the port may not be ready, or the device may not be powered on. Check both the port and the device to ensure they are functioning correctly.
Why are Queclink GPS messages not being reported to the backend server?
If messages from your Queclink GPS device aren't reaching the backend server, it could be due to an incorrect APN. You should ask the network operator for the correct APN. Also, verify that the backend server's IP address and port are accurate and that the IP address is a valid internet address.
What to do if Queclink GPS device can't get GPS fix?
If your Queclink GPS device is unable to get a GPS fix, the GPS signal might be weak. Try moving the device to a location with a clear view of the sky. Also, ensure the antenna side of the device faces upwards towards the sky.
Why does Queclink GPS CEL LED flash quickly after being turned on?
If the CEL LED on your Queclink GPS device flashes quickly after turning it on, it indicates a weak signal or that the device hasn't registered on the network. Move the device to an area with better network coverage.
