I have purchased LoRa/LoRaWAN Gateway-868 MHz kit with the raspberry pi and when I tried to set up the gateway. putty is always showing the blank screen and in PRI2 bridge and well as RHF0M301 shows blinking green light. I am from India please help me with my doubt that why I am not getting boot screen with rxhf login in putty terminal and also I cannot see any light glowing in rpi3 that comes with kit even after powering on with power adapter given inside the kit of Lora.
