Hello @MaBe,
I did and it does the same thing - returns an empty array.>require("Wifi").scan(function(arrayOfAcessPoints){print(arrayOfAcessPoints);}); =undefined [ ] -
Ordered 3 Wemos d1 minis from different suppliers. Will see how they perform while this remains a mystery...

Enabled WiFi logging

Just checked Micropython on this board - WiFi works great.

@Ollie do you mean shorting the antenna connector? Tried that out of desperation and also flashed espruino_1v85_esp8266_combined_512.bin - issue remains.

Yes - the WiFi details are correct. "simple" is the actual SSID and also is the password. I did try your code snippet.
I would like to point out, that WiFi credentials get set properly:
>wifi.getDetails() ={ "status": "no_ap_found", "ssid": "simple", "password": "12345678", "rssi": 0, "savedSsid": null }Looks like it's unable to use the radio at all somehow.

@Wilberforce I have added the antenna - getting the same result. esp-open-rtos works fine with and without the antenna though.
@CrashingDutchman It's being powered through USB out of my laptop - same power source as with esp-open-rtos. Just tried powering it with 12V 1A adapter - didn't see any improvement. Also erased and re-flashed using the new power source.
What else can we try? :D

Here's what it does after wifi.connect():

Okay.

Compiled my own firmware from latest source - same result.
Also, wifi.scan() returns an empty object. I have a few APs around for sure.>wifi.scan(function(ap){print(ap);}); =undefined [ ]Tried with esp_init_data_default.bin at 0x3FC000 and without it. I'm also erasing before every flash.
Thank you everybody for your time trying to help out.
What I mean to say here is that esp-open-rtos works just fine at this moment. As soon as I flash it with Espruino I encounter the wifi problem.
@MaBe I've already tried changing to b/g/n - doesn't improve anything.
