I tried it without Wi-Fi connection too.
Which capacitor should I use?
-
I'm using this schema. Just unplug GPOI0 from the ground after flashing.

@Ollie, I just tried 1.87 and console started giving a response. I disconnected gpio0 and launched the Web IDE:
>1+1 =2 >wifi.getStatus() Uncaught ReferenceError: "wifi" is not defined at line 1 col 5 wifi.getStatus() ^ >var wifi = require("Wifi"); =function () { [native code] } >wifi.connect("TP-LINK", {password: "password"},function(err){if(err)console.log(err);else console.log("connected!");}) =undefined connected! >wifi.getStatus() ={ "mode": "sta+ap", "station": "connected", "ap": "enabled", "phy": "11n", "powersave": "ps-poll", "savedMode": "off" } >But when I tried to upload a simple sketch I received errors:
Sketch:
setInterval(function() { console.log('Hello, world!'); }, 3000);Output:

@Ollie, yes, I tried
screentoo. The result is the same - empty screen. And yes, I erased it before flashing.Before Espruino I used Arduino IDE to write firmware for it and it worked without problems.
-
@Frida, yes, I tried to disconnect gpio0 after flashing, but the result is the same.
@Wilberforce, yes, I set it to 115200.
Does
/dev/tty.usbserialor/dev/cu.usbserialmatter on flashing stage or on connection from Web IDE? Which should I choose?By the way, when I'm trying to write any text in the console a small LED on USB-TTL is flashing on every button push, but the console is still empty.

Hi!
I can't make ESP8266 work with Espruino. I'm using USB-TTL converter. Flashing works without any problems:
esptool.py -p /dev/tty.usbserial write_flash 0 espruino_1v90_esp8266_combined_512.bin esptool.py v1.2.1 Connecting... Auto-detected Flash size: 8m Running Cesanta flasher stub... Flash params set to 0x0020 Writing 524288 @ 0x0... 524288 (100 %) Wrote 524288 bytes at 0x0 in 47.2 seconds (88.9 kbit/s)... Leaving...After that, I disconnect it from the computer and connect again (GPIO to ground) and launch Espruino Web IDE. I choose
/dev/tty.usbserialand the connection is established. But I can't write anything in the console at the left.What should I do to make it work?

Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
Finally bought a capacitor (47uF, 16V) and ESP8266 started working!
Thank you very much, @Ollie! And Happy New Year to all!
