Re: [agail-dev] Setting up a resin hotspot on RPi

[Georgios Michalakidis <georgios@xxxxxxxx>]

Hi Nikos,

(Hope you’re well, and,) This is in response to your AGAIL-DEV list query.

First things first, is the device you’re using an RPi 3? If so, RPi3 defaults to wlan0, not wlan1 — just make sure you’re using the correct one. You can run ifconfig on the device host container and it'll show list of interfaces.

Also, I went through the instructions and perhaps they can be a bit more obvious — especially when it comes to the directory structure. We will look to fix this.

From the documentation, it should be noted that you will not see a new file created in resin-boot/system-connections because there isn't a two way binding. 
The way it works is that on device boot, the files in resin-boot/system-connections are copied into /mnt/state/root-overlay/etc/NetworkManager/system-connections without removing any files from the destination.
That directory is then bind mounted to /etc/NetworkManager/system-connections in the root filesystem on the Host.

So, basically, delete your existing resin-wifi-1 file in /mnt/boot/system-connections and in /mnt/state/root-overlay/etc/NetworkManager/system-connections/

Your resin-hotspot files should then look like:

root@2xxxx1b:~# find / | grep resin-hotspot
/mnt/state/root-overlay/etc/NetworkManager/system-connections/resin-hotspot
/mnt/boot/system-connections/resin-hotspot
/etc/NetworkManager/system-connections/resin-hotspot
find: /proc/1152/fd/11: No such file or directory
root@276201b:~# cat /mnt/boot/system-connections/resin-hotspot
[connection]
id=resin-hotspot
uuid=36xxxx57-axxd-4xxf-axx4-exxxxxxxxxx7
type=wifi
autoconnect=false
interface-name=wlan0

seen-bssids=
ssid=resin-xxx-testhotspot

pairwise=
proto=
psk=verysecurepassword

[ipv4]
dns-search=
method=shared

[ipv6]
addr-gen-mode=stable-privacy
dns-search=
method=auto

Reboot, and with: nmcli c up resin-hotspot

You should have your WiFi hotspot up.

Hope this helps,
