Concentrator won't start about rpi-ttn-gateway HOT 9 CLOSED

When I'm installing the software native on my RaspberryPi, the concentrator works fine, so the hardware is working fine.

I'm running on a RaspberryPi3 with HypriotOS v1.4. Any hint would be highly appreciated.

Which backplane are you using? We are using Charles' backplane which has the reset pin connected to PIN 17 of the RPi. You might have it connected to PIN 25?

I'm using the simple Gnz from Tindie, is that the same? How can I manually trigger a reset?

The pin re-assignment is the most likely reason for what you're seeing I believe. Could you please try commenting line 34 of the Dockerfile and build your own image (either on macOS or the Pi)?

from rpi-ttn-gateway.

YES! That looks much better!! That seems to solve the issue!

Now I just have one last question about the MAC that needs to be supplied, how do you format that? When I run it native, I get B827EBFFFEA10C04 and I don't seem to get FFFE when running the docker image?

Great, good to hear!

Just hours before you raised this issue we had been discussing options for making that pin assignment configureable (Dockerfile env config, multiple Dockerfiles in subfolders, custom base image with extensions, etc.). I'm positive we'll make "that", which ever way it's going to be, available sooner rather than later.

I'm not sure about your MAC address question, though. The address on the host OS (Hypriot) is the same as in the Docker container:

$ cat /sys/class/net/eth0/address
b8:27:eb:97:73:e2
$ docker run -it --privileged --net=host --restart=always netceteragroup/rpi-ttn-gateway /bin/bash
root@black-pearl:/opt/ttn-gateway/bin# cat /sys/class/net/eth0/address
b8:27:eb:97:73:e2

However, if by running 'native' you mean running the install.sh from TTN ZH GitHub repo then https://github.com/ttn-zh/ic880a-gateway/blob/master/install.sh#L47 is probably what you're looking for.
If I'm not mistaken gateway_ID in local_conf.json simply has to be a unique 8 byte number - the MAC address is as good as any and just so happens to be 64 bits.

ok, yes, this is what I mean. Is there a specific reason that ttn-zh injects the FFFE and you don't?

Anyways, after correcting several typos on my end, I realized that I can just supply the gateway_ID in that format to the container and it works then as I want it to.

Thanks for the help!!

Now we do 😉 Sorry my previous comment

was of course wrong. The Pi MAC address is 48 bits, not 64 bits. I added a note about that to the README (→ GATEWAY_EUI).

Awesome! Thanks for the clarification!
