"not connected" on TTN. #66

Closed shavaizknz98 closed 4 years ago

shavaizknz98 commented 4 years ago

Hello, I am currently creating a LoRaWAN outdoor multi-channel gateway fora university project. I purchased a RPi3 B+ and an ic880A and followed the guide on https://github.com/ttn-zh/ic880a-gateway/wiki, I even added my gateway ID to the remote-config repo. However, by the end of the installation my gateway status is “not connected” on TTN. Can anyone please help out. Here are some logs from my RPi.

After running sudo systemctl status ttn-gateway.service I receive the following,

ttn@ttn-gateway:~ $ sudo systemctl status ttn-gateway.service

And after running sudo tcpdump -AUq port 1700 I get,

What's your gateway EUI?

shavaizknz98 commented 4 years ago

Do you mean the gateway ID? Here it is B827EBFFFEBF634A

tmallikarachchi commented 4 years ago

Did you find a solution for this? I'm running into a similar issue. In my case, I get a mixed from time to time. Here the are the outputs when I run sudo systemctl status ttn-gateway.service

I'm using RPi 3. The status in things network is always seen as "not connected."

shavaizknz98 commented 4 years ago

My issue was fixed a couple of days after. I just reset the RPi and followed all the instructions again. Magically worked somehow, still do not know what the original issue was.

tmallikarachchi commented 4 years ago

Thats great. Could you please be able to confirm whether the pin configuration in the description matches the diagram? My setup seem a bit different compared to the picture in the wiki page.

gonzalocasas commented 4 years ago

@shavaizknz98 thanks for updating. @tmallikarachchi these issues are always related to some deviation of the instructions, or some misconfiguration. Please double and triple check your wiring is the same as in the instructions and you followed all steps correctly.

tmallikarachchi commented 4 years ago

I managed to resolve this yesterday!. It was an issue with pin configuration in raspberry pi. I had connected the pins in RPi incorrectly. Followed the layout given in https://www.raspberrypi.org/documentation/usage/gpio/
