Look's like the usbc points to the serial device, check this

The highest power setting is "none" which is onl available when BLE is switched off.

You can download latests build here

It is now posible to build a ESP32C with uart, check the board file.

i think it has to do with wifi power setting mentioned here

https://github.com/espressif/arduino-esp­32/issues/6767#issuecomment-1145661485

Wifi is not broken on 4.4.7, we need to understand that if the board is already connected a another connect will break things. The folowing code will check for that situation:

var ssid="SSID";
var password="password";

var wifi=require("Wifi");
wifi.stopAP(()=> {
     print(wifi.getStatus());
     var status = wifi.getStatus();
     if (status.ssid == ssid && status.station == "connected"){
       print(wifi.getIP());
     } else {
       wifi.connect(ssid, {password: password}, function() {
         print(wifi.getIP());
       });
     }
});

Line 8 is the breakthrough: Do not connect again if already connected

You can upload this code as ofen as you like and the ESP32 board will not reboot!

Edit:
Wow, tested today and it is broken again .......

A clone of an espressif esp32c3 devkitm-1

Got a new ESP32C3 divice with more pins and a UART instead of o USB-CDC interface. Not happy with my modification and still testing differen devices, a pm will follow.

@Gordon What do you thing about having a optional timing setting like this:

np = require("neopixel").config(t0h : 350, tol : 900, t1h : 700, t1l : 600);

Timing from datasheets WS2812.pdf, WS2811.pdf

Signal     WS2812-800KHz    WS2811-400KHz    WS2811-800KHz

T0H_NS      350              500              250
T0L_NS      800              2000             1000

T1H_NS      700              1200             600
T1L_NS      600              1300             650             

Tolerance is +-150ns

Coded in Espruino:

Signal     ESP32

T0H_NS      350       
T0L_NS      900 

T1H_NS      900   
T1L_NS      350 

Now testing some WS2812 and WS2811 with this setting:

Signal     ESP32

T0H_NS      350       
T0L_NS      900 

T1H_NS      700   
T1L_NS      600 

Data sheets for ws2812 and ws2811 show different timings for 1 and 0. Did anyone tested ws2811?

Has anyone else got WiFi working? I'm sure I did test this originally and it worked, so I'm not sure what's up...

Yes it worked before, but now its broken for ESP32C3_IDF4

Try this

// Test ESP32 WiFi event callbacks
var ssid="<SSID>";
var password="<PASSWORD>";

var wifi=require("Wifi");

wifi.on("associated", function(details) {
	console.log("  Event-> associated: " + JSON.stringify(details));
});
wifi.on("connected", function(details) {
	console.log("  Event-> connected: " + JSON.stringify(details));
});
wifi.on("disconnected", function(details) {
	console.log("  Event-> disconnected: " + JSON.stringify(details));
});
wifi.on("auth_change", function(details) {
	console.log("  Event-> auth_change: " + JSON.stringify(details));
});
wifi.on("dhcp_timeout", function(details) {
	console.log("  Event-> dhcp_timeout: " + JSON.stringify(details));
});
wifi.on("probe_recv", function(details) {
	console.log("  Event-> probe_recv: " + JSON.stringify(details));
});
wifi.on("sta_joined", function(details) {
	console.log("  Event-> sta_joined: " + JSON.stringify(details));
});
wifi.on("sta_left", function(details) {
	console.log("  Event-> sta_left: " + JSON.stringify(details));
});

level = 0;
wifi.stopAP(()=> {
  level ++;
  print("I stoped AP", level);
  wifi.disconnect(()=>{
    level ++;
    print("II disconnect station", level);
    wifi.connect(ssid, {password: password}, function() {
      level ++;
	    console.log("III Connect completed", level);
    });
  });
});

It is definitly working! This is also an issue on ESP32 devices and even with earlier IDF version like 3.x.

Edit:

Ok, this is only true for ESP32_IDF4

ESP32C3_IDF4 latest build does not connect anymore to an AP

Event-> disconnected: {.......,"reason":"2","msg":"AUTH_EXPIRE­"}

please stop posing same issue in this conversation too.

In this case I guess you are already connected, check with wifi.getState()

Hi @user158605 this is a known issue, check the workaround for this.

@Gordon Many thanks!

Nice and many thanks for your effort. I will give it a try over the weekend.

you can call git on command line:
git status show the files that are changed
git diff filname show changes
git checkout filname revert changes

@SimonGAndrews did you check this Arduino thread?
https://forum.arduino.cc/t/problem-with-­analogread-on-esp32-c3/892651

Many thanks, hope we get more tester on board for those devices.

im trying to build a set of wifi tests, refactoring @tve s esp8266 tests

please also check this tests from @Wilberforce

https://github.com/espruino/Espruino/tre­e/master/targets/esp32/tests

esp32 boards need 115200bps

if you have the .elf file you can use use

https://maximeborges.github.io/esp-stack­­trace-decoder/

upload .elf file and enter the Stack trace CPU wise to get detail about the function

use this export

export PORT=<your serial port>
