Developing and Deploying devices

[Robert Helling]

Hi,

I have been thinking a bit more about setting up a small device (C.H.I.P. or similar) to do the dive computer read out and communication with the mobile device.

One thing I am worried about is how to collaboratively develop for such a target. It is quite likely that we have to modify system files and settings (like startup, maybe configure BT or networking, instilling packages etc). How can we put that in version control? Do everything with a script and version control that script? For configuration files, one could have those in a directory under git and then have a small script that writes them in the appropriate places (and sets permissions etc). But maybe people have better ideas. Am I reinventing a packaging system?

The other thing is deployment. Initially, that’s simple, we provide disk images. But then, what is the upgrade path? Connect to wifi and do git pull? apt-get upgrade/update? Get a new disk image? That needs to be thought about as well for devices like this.

Any opinions?

Best
Robert
