Loading...What to do if there is no response from UART when configuring Queclink GPS GL300 through UART?
If you're not getting any response from UART when configuring your Queclink GPS GL300 via UART: * The device might be in power saving mode. Disconnect and reconnect the Data_Cable_M. This will take the device out of power saving mode for 10 seconds. * Try using the GL300 manager tool again to wake up the device.
Why can't Queclink GL300 messages be reported to the backend server by GPRS?
If messages from your Queclink GPS device aren't reaching the backend server via GPRS, there might be a few reasons: * The SIM card may not support GPRS. Try using a SIM card that does. * The APN settings could be incorrect. Contact your network operator to verify the correct APN. * The backend server's IP address or port might be wrong. Ensure the IP address is a valid internet address.
Why does the GSM LED flash quickly on my Queclink GPS GL300?
If the GSM LED on your Queclink GPS GL300 flashes rapidly after turning it on, it could be due to these reasons: * A missing SIM card. Please insert the SIM card. * Weak signal, preventing network registration. Move the device to an area with better GSM coverage. * The SIM card is PIN locked. Use a SIM card without SIM-PIN, or unlock the SIM-PIN.
What to do if Queclink GPS GL300 can't get successful GPS fixing?
If your Queclink GPS GL300 is unable to get a GPS fix, it might be due to a weak GPS signal. Move the device to a location with a clear view of the sky, ensuring the top surface (the side with the LED) faces upwards.
How to fix unable to power off Queclink GPS GL300?
If you're unable to power off your Queclink GPS GL300, it could be due to the following: * The power key function might be disabled. Enable it using the command AT+GTFKS. * A charger or external battery is connected. Disconnect them and try again.
