Wifi problem with espruino 2.01

Hello,

I am seeing a message that I believe comes from the lower level wifi interface after espruino idles for a while.

wifi.connect(wifi_options.ssid, { password: wifi_options.password },
  e => { print("WIFI: " + e); }
);
wifi.on('connected', () => {
  print('WIFI:', wifi.getIP());
  setTimeout(() => { httpServer(); }, 1000);
});
wifi.on('disconnected', () => {
  print("WIFI: Reconnecting...");
  setTimeout(() => { wifi.connect(wifi_options.ssid, {password: wifi_options.password}); }, 5000);
});

There has been a problem with wifi for all versions following espruino_2v00.42 (due to espressif's SDK 3.1) . Feel free to follow along here https://github.com/espruino/Espruino/issues/1571. I don't think a stable wifi release has been cut yet, as I just tried the latest and I'm seeing the same results. @Wilberforce and @JumJum have been making good progress though!

I noticed that trying to connect to ESP_203D1D with my desktop computer makes espruino fail.

Happened as soon as I tried to connect:

abort() was called at PC 0x40084b1f on core 0

or the normal error we see:
E (36210) event: post event to user fail!
E (39052) event: post event to user fail!
E (41894) event: post event to user fail!
E (44737) event: post event to user fail!

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

Mention another user by @username

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
