Setup Troubleshooting

Possible Cause
USB was not set up properly
1. USB was not set up properly.
2. COM port or baud rate value is
incorrect.
1. If it is used inside a vehicle, the
anti-sunscreen film on the
windshield may interfere and
weaken the GNSS signal.
2. The vehicle might be under some
area with a dense overhead canopy
such as a forest, buildings, tunnels,
etc.
Note: If these troubleshooting steps do not solve the problem, please contact us or send the
module back to us for inspection.

Solution
Check to see if the Development Kit was
set up properly, and make sure that the
device is receiving enough power
through the USB cable (red LED should
light up continuously).
1. Check to see if the USB connector
to the PC or Development Kit is
connected properly.
2. Double check to see if the proper
COM port and baud rate value are
selected.
For both problems, the user may
connect an external active antenna to
the Development Kit, and then place the
antenna on top of the car's roof to
improve signal reception.
