Hi!
This is my first post here, so apologies if I did something wrong 
I have been working on some WAMP components to be used for a personal project, the idea is to be able to control the GPIO pins on the Raspberry Pi and ensuring all components connected stay in sync, I call it pigpio-wamp, source code available https://github.com/om26er/pigpio-wamp. Right now the code base is pretty simple but I plan to add more features in future.
I already released the package as a snap to Ubuntu store and can be installed on a Ubuntu based system using:
$ sudo snap install pigpio --edge --devmode
``
For non-snap based Linux systems use runner
executable on the root of the project.
Currently it has to be run from command line using below command, I’ll make that a daemon that starts automatically in the background.
$ sudo pigpio
``
To set the address of a WAMP router and a realm on it you have to call the below command first
$ sudo snap set pigpio crossbar=ws://your_wamp_router_ip/ realm=realm1
``
I am also working on an Android app to control those GPIO pins but its not releasable just yet (though its already functional), but it should be in a few days.
Cheer!
Hi Omer,
cool! thanks for sharing!
one question regarding snap packaging:
https://github.com/om26er/pigpio-wamp/blob/master/snap/snapcraft.yaml#L8
is is possible to use release mode (not devmode) and explicitly grant access to the GPIO from within the snap?
Cheers,
/Tobias

Hi Tobias,
It seems we cannot have snap in confined
mode on the Ubuntu Core image that is released due to a bug[1]
​ but I had inquired in their forums and they told me to use the ‘candidate’ image[2]. That way a our snap will only be allowed to use the GPIO pins that we allow from the host (through snap connect
command).

Thanks for digging this out!
We probably would like to have a doc page or something dedicated to Ubuntu Core / snaps with Autobahn in general, and on the Pi in particular.
Such hard to find tips like this one would naturally be a nice addition then to such a page.
As we are talking here, do you know when the Core flavor of 17.04 is due?
I am asking, because of kernel version - as far as I know, ubuntu 17.04 (core also?) is based on kernel 4.10, right?
There are some interesting embedded devices (Marvell SoC based) that only have full Linux mainline support beginning with 4.10
Another Q: is Ubuntu Core able to do remote OTA updates of the kernel and userland snaps _across_ major versions?
Asking because 17.04 won't be a LTS. So could I update a Core 17.04 device over the air to 18.04 LTS once that comes out?

If you find answers to above, please collect them "somewhere" - we'll move them to a yet to be decided place then later.
Just want to make sure such hard to find and useful infos are not lost.
Rgd "somewhere": these are probably not AB XX specific infos, but general snap'ped AB infos, or Pi specific infos.
Best place for Pi related infos would be
https://github.com/crossbario/iotcookbook/blob/master/device/pi/README.md
(there are already some Docker notes there .. hence infos rgd snaps on Pi would fit naturally)
