Why GPS location information can’t be seen in device?
1. Check if the status of the module on the device is present
2. Check if the GPS antenna is connected properly. The antenna should be placed in a wideand unobstructed place to have a signal. If the vehicle passes through the tunnel during thedriving process or if there is a tall building or a large tree, the signal will not be received. Thisis normal. Phenomenon
Why we can’t see vehicle location while device is online?
1. Please check the set GPS upload interval on the platform
2. The GPS signal on the device can receive normal positioning information for the platform, so please check whether the GPS signal on the device is displayed normally.
