I’ve successfully setup a gateway (Pi 3+IMST), and the endnode (Adafruit Feather M0 with RFM95W) as well. The gateway is receiving the data, I can see the data coming up in TTN console. I’ve integrated TTN with Ubidots; I can see the visualization of all the measurements being made. Thanks to the community of TTN, who helped me at every juncture.
The only challenge in this whole exercise is the internet connectivity for the gateway, barring which the setup is in function for the past 2 weeks. I’m using the institute wide LAN connection of our university. As long as I’ve connected through a router, I’m able to see in TTN console that the gateway is connected, and that it is showing activity. By activity I mean, it is getting refreshed every 30sec, and also that the endnode is able to talk to the gateway. But since there are restrictions about using routers in our lab, I wanted to find an alternative: (a) Connecting to LAN port directly, (b) Using campus WiFi of our university, and © Using my personal mobile as hotspot. I’ve tried all three cases (except the second, it didn’t work), and it was observed that the console shows connected but it does no activity, as a result my endnode stopped speaking to the gateway.
I suspect that the campus network constraints/restrictions could have resulted in the non-functioning of gateway. But in case of my mobile being used as wifi hotspot, the issue should not have arisen. Surprisingly, when I’ve connected Pi to a desktop, I was able to access internet in the desktop. What could be a way out? Should I explore other alternative like cellular backhaul (3G/4G). But I’m afraid that the cost might increase, and it might have compatibility issues as well.
