Hello guys, I’ve been usin Resin for a couple of months now and everything has been going great but now I’m struggling to to add cellular connection so my machine (Raspberry Pi 3) doesn’t need to rely on Wifi availability.
I’m not sure if it’s similar to this issue but I’ve tried some tricks from there:
I have a Hologram Nova modem with a SIM card that works well when tested on my own Ubuntu Linux machine with very basic configuration (file under
[connection] id=hologram-cellular type=gsm autoconnect=true [gsm] apn=hologram number= password= username= [serial] baud=115200 [ipv4] method=auto [ipv6] addr-gen-mode=stable-privacy method=auto
I can then connect and navigate well, although I need to connect manually. Then I tried to replicate the same on the R-Pi3 (Resin OS 2.7.8+rev1) doing the following:
create new Application, then add new device “Ethernet Only” with this Dockerfile:
CMD [“echo”, “hello”]
changed boot/config.txt to add max_usb_current=1 and safe_mode_gpio=4
Added my cellular configuration file (as above) to boot/system-connections
unplug/plug modem again with the device on
But I still can’t get a connection established. Also tried adding autoconnect-priority, unplugging + plugging the modem while the machine was on, nothing worked.
Any tips? I’m trying to investigate it further but running out of ideas here on how to troubleshoot this.
I suppose it’s not possible to log on to the machine directly via keyboard + monitor, right?
One thing I was thinking was to add wi-fi connection, then try and open a terminal via the dashboard to play around trying to troubleshoot the modem, but I’m not sure which commands could help here and if I should use either the Host OS terminal or the container.
Any help would be appreciated.
