[Solved] ESP8266 problem on Espruino pico

Indeed.
I reduced a bit the code, did a full restart of everything and uploaded the code at the bottom of this post under the dashed line. The output is just below that.

You can see that it is actually the serial garbage (which is a known problem in 0.9.2.4), that is the cause of the (initial) error. That's why I originally added the setTimeout. Anyway, I took that setTimeout away for now.

After uploading and executing that code (which failed), I entered the following in the command window

wifi.connect("solarsystem","tmpjoimc", print);

That resulted in:

=undefined
CWMODE failed: AT+CWMODE=1

To display the full error, I entered this:

wifi.connect("solarsystem","tmpjoimc", function(err) {if (err) throw err;});

which then resulted in:

=undefined

in function "d" called from line 1 col 16
{e=void 0;d&&d()}
                ^

which in turn is again the same error as in all previous tests.

I'll put together another pico/esp8266 to see what that gives.

====================================================

Serial2.setup(9600, { rx: A3, tx : A2 });
var wifi = require("ESP8266WiFi").connect(Serial2, function(err) {
  if (err) throw err;
  wifi.reset(function(err) {
    if (err) throw err;
      //your code to be executed after 1 seconds
      wifi.connect("solarsystem","tmpjoimc", print);
  }); //wifi.reset
}); //require

>reset();
