Overview
The Inventory Master GPS tester healthcare connects the gateway via OTAA to join the network. It has an LCD screen. It can test the Uplink and Downstream packet loss rate. Meanwhile users can get RSSI and SNR for gateway transmission. Users can turn on the GPS to display the latitude and longitude coordinates of the device, and check the LoRoWAN TM CLASS type and the firmware version of the LoRa tester.
