ESP8266 ESP-01 with AT version:0.50.0.0

@MichaelPralow argh, what a mess! Why can't they just leave it alone?

IMO we should stick with the existing ESP8266WiFi_0v25 module unless it turns out they've changed something so drastic in 0.50 that we can't do it easily. I've just committed a change to fix it for 0.50 and will update the website over the next day or so.

Does anyone have a copy of this 0.50.0.0 firmware? I'd like to get a download link for it on the Espruino website.

would there be any interest in an alternative app that accepted as input and returned as output ... JSON strings?

I don't think it would make much difference. It'd be a little faster, but so what? IMO it's far more important that someone can buy an ESP8266 and use it without having to re-flash the firmware. I'd also hope that the 0.50.0.0 firmware is quite well tested and stable now...

AT command support has to exist in Espruino for GSM support (and also some other things like BT devices), so it's not such a big deal.
