OTA updates with Espruino?

Hi everyone,

I recently saw a post about FOTA (Firmware over the air) where they explained how to update the firmware over the air. Now I was wondering if I could upload a .js file like in the Espruino IDE over the air (via WIFI). This script would then be executed like any other script in Espuino. But I couldn't find anything about that online (or I might just be bad at googling).

I hope you guys can point me in the right direction.

What kind of Espruino board were you thinking of using?

If you're using a bare ESP8266 then you can connect over the network with the Web IDE and everything will be fine, but the normal Espruino boards need some software on them first.

Something like this should work though:

var server = require("net").createServer(function(c) {
  c.pipe(LoopbackA);
  LoopbackA.pipe(c);
  LoopbackB.setConsole();
});
server.listen(1234);

You might also want to make a new reset() function that doesn't completely reset the board, as normally when the Web IDE sends reset() then it would stop your network connection.

At some point I'll build the functionality straight into the firmware, but it's not there at the moment.

The other option you have is for Espruino to connect to a server, download the javascript, and then execute it with eval

okay thanks for the information Gordon. I am planning on using an ESP8266 I think the eval() option works best with my requirements. I will have you do some research into it.

thanks for your help!
