Milesight LoRaWAN gateways support GPS which is used to locate the position. The GPS data will be sent to platform connected as well, the time will be 10 seconds every time. The models supporting GPS are as follows:
- UG67
- UG87
- UG85 (Optional)
Symptom 1: No GPS data in the web GUI of gateway.
Checklist:
1. Check if gateway model supports GPS. GPS is supported for UG67/UG87 by default. For UG85, if the model does not includes -G, this gateway does not support GPS.
2. Upgrade gateway to latest version. Click here to find the Latest firmware.
3. Ensure the gateway is placed outdoors or beside the window to receive good GPS signal.
4. For UG8x, check if GPS antenna is connected to correct GPS antenna connector and not break. If it connects to other connectors, gateway can not get good GPS signal.
Symptom 2: No GPS data in network server.
Checklist:
1. Ensure the gateway is online in your network server.
2. Go to Maintenance -> Log -> System Log to download log package and unzip it.
Try to check the 'lora-pkt-fwd.log', you will find some logs about GPS.
