Testing new wifi bootstrap script process

Thanks for your interest in helping test something new!

We have a new process for setting up OpenAPS that may be easier for people, but need some help testing.

What it does:

  • Finds and helps you set up your wifi automatically
  • Simplifies the old Phases 0 and 2 in the documentation to be more streamlined.

What you should do:

Thanks in advance for help testing!

Works like a charm, Dana! Just used it to setup a new rig and all went smoothly! Just a few notes...

  • Would be nice to handle wifi SSIDs with spaces in them, perhaps just check the input string for double quotes on the beginning and end and remove them. I did have to run it twice since I have a ssid with a space in it. (I know, I know… just never got around to changing it long ago and it kinda stuck with me)
  • Got “sudo: unable to resolve host jubilinux” on installing openaps dependencies and when running oref0-setup but I checked and all the hostname stuff got setup correctly. Doesn’t seem to matter from what I can tell, but I wouldn’t think we should get those errors.
  • Might be handy to automatically create the .bash_profile? Would make quick verification/troubleshooting super easy.

Agreed on supporting wifi SSIDs with spaces. Care to test that and PR in what works?

The "unable to resolve host" stuff should go away after rebooting onto the new hostname. We decided not to force a reboot until after we're done with everything, though, so that's an acceptable and harmless cosmetic bug IMO.

I think oref0-setup does all the .bash_profile stuff automatically. What are you seeing / referring to there?

I'll see if I can get a minute tonight to look at the quotes/spaces thing....

(Referring to the bash_profile implemented in the docs). Well I guess on reboot I didn't see aliases available was all. I had to set up the aliases in bash_profile after installing dev the other day... wasn't aware it was supposed to do it automatically. Im probably just not aware of the expected behavior.

Agree with, jyaw, worked like a charm, I think. This is my first rig so the new script came just in time. But that also means I can't tell you if everything is working as expected, at least not yet. Once I fixed the wireless stability problem everything completed without error. I'm now going to get to know my medtronic pump, and take this all out for a spin. Thanks, Dana!

Dana, this being my first install I'm wondering where this leaves me in the build process? Your script completed without error, so what do I do next? Where do I pickup the build in the OpenAPS docs?

@thanksegon you should have a basic loop going, but you'll want to head back to the main docs and pick up here for step 3 (watch the logs) and step 4 (change maxIOB and any other settings you want to customize): http://openaps.readthedocs.io/en/latest/docs/walkthrough/phase-2/oref0-setup.html#step-3-watch-the-logs-required

Thanks, Dana. It looked as if the new script updated my azure site with the Nightscout OpenAPS features, yes? My NS site doesn't show these yet, so I'm wondering if I need to do anything further.

The script was dropping out right before the last line. I'm guessing an error with iwgetid.
I added a sleep 10 before the line echo -ne "\nWifi SSID: "; iwgetid -r and that fixed the problem. My rig must be a little slower than most in getting a connection. Here is a little snippet of the error I was seeing:

Unfortunately this method didn't work for me. It hung near the very last step for about three hours, so I quit terminal. After that I was unable to restart the process and had to login via my router and start from scratch the traditional way. Not sure what made things hang, but that's what happened.
