Self Updating Mechanism

[Diaonic]

I really don't want to reinvent the wheel if I don't have to. Whats the best way to implement some type of software versioning / updating routine. There will be many ESP8266 in the field and I need them to periodically check for a new version of my .py files and update accordingly.

I've seen references to upip, is that the best way?

Thanks in advance.

If your application is sufficiently small not to need frozen bytecode then I'd consider using upip. I don't know if anyone has run it programmatically but there's no obvious reason why you shouldn't. It lacks an update mechanism (it only has install) but I'm sure you could invent a way of checking for a new version on PyPi.

Hi;

I have done this using a nodejs webserver to host the update files, using express server-side it is pretty trivial:

Code: Select all

var express = require('express');
var app = express();
var home = '/nfs/qnap/data/uPython/updates';

app.get('/*', function (req, res) {
  if((/robots|sitemap|favicon/).test(req.url)) return res.end();
  var path = home+req.url;
  console.log('path:',path);
  try {
    
    res.download(path);
  } catch(e){
    res.end()  
  }

});

app.listen(process.env.PORT, function () {
  console.log('Listening on port: '+process.env.PORT);
});

Client side I wrote a wget() function to download required files.
