ttn-gateway service entered failed state

[thayuriko]

Hey guys, After installing the install.sh and rebooting, I wanted to check if the service was running (since it was not being shown in the console) and here is what I got:

rxhf@radek-gw2:~/ic880a-gateway $ sudo service ttn-gateway status ● ttn-gateway.service - The Things Network Gateway Loaded: loaded (/lib/systemd/system/ttn-gateway.service; enabled) Active: activating (auto-restart) (Result: exit-code) since Fri 2017-08-04 17:33:02 UTC; 4s ago Process: 9538 ExecStart=/opt/ttn-gateway/bin/start.sh (code=exited, status=1/FAILURE) Main PID: 9538 (code=exited, status=1/FAILURE)

I get this "failed to start the concentrator" quite often in my other gateway, but after retrying a few times the gps_packet_forward it works. Should I just retry with this one as well? If so, how? By rebooting it and rechecking the status of the service over and over?

Hi @thayuriko, I wouldn't use the gps_packet_forwarder, it's not really tested much. The poly_packet_forwarder on the other hand, is used by the whole community, and it's been working pretty well... About the error message, the issue with failed to start the concentrator means that the SPI connection between the RPi and the concentrator is not working correctly. This can be for a multitude of reasons:

• If the wiring is wrong, so, you would get this consistently every single time.
• If, however, you have the adapter board instead of jumper wires between boards, the reset pin could be wrong. This can cause the error to appear mostly every time.
• If the power supply unit is not delivering enough (make sure it's 2A, and a good quality one), you might also get this very often. If you get it intermittently, this might be the first to examine.

Cheers gonzalo

Thank you, Gonzalo. I changed the Reset Pin as you recommended and now it works! :) For those who are struggling with the same thing (and using a RHF0M301 + RPi3 + adaptor board), check this https://github.com/ttn-zh/ic880a-gateway/issues/11#issuecomment-320494038

what's the correct pin number ?
