Set wifi creds not working?

Connectivity
1

So I’ve tried for hours to figure this out, but I can’t even get this thing to connect to a open network using code.

Here is what I do:
setup argon to connect to wifi using doctor tool
use webide to program unit
use serial to run WiFi.clearCredentials();
argon stays connected until restarted
use serial to restart unit
argon is now disconnected
use serial to set ssid var
use serial to save new ssid WiFi.setCredentials(ssid);
still not connected
use serial to run WiFi.connect();
still not connected
use serial to restart argon
still will not connect.

What is going on with this?

I can even verify my commands are working by not clearing creds and running all the same commands. I use serial to print ssid var and WiFi.SSID() but it will not change WiFi.SSID().

Which overload of WiFi.setCredentials() are you using?

You need to make sure the security is WLAN_SEC_UNSEC and cipher is WLAN_CIPHER_NOT_SET. Just setting an empty password will not work.

Docs say:

// Connects to an unsecured network.
WiFi.setCredentials(ssid);
WiFi.setCredentials(“My_Router_Is_Big”);

// Connects to a network secured with WPA2 credentials.
WiFi.setCredentials(ssid, password);
WiFi.setCredentials(“My_Router”, “mypasswordishuge”);

// Connects to a network with a specified authentication procedure.
// Options are WPA2, WPA, or WEP.
WiFi.setCredentials(ssid, password, auth);
WiFi.setCredentials(“My_Router”, “wepistheworst”, WEP);

Can you give me some working examples for wpa2 and open connections, please?

Also I don’t know what overload is. I’m using version 4.0.0 OS.

Open Wi-Fi:

WiFi.setCredentials(ssid, "", UNSEC);

WPA2:

WiFi.setCredentials(ssid, password, WPA2);

Also the Argon can’t connect a Wi-Fi network with a hidden SSID. Since it worked from web device doctor, that’s presumably not the case, but I thought I’d mention it just in case.

By the way, if you’re really setting the Wi-Fi credentials from USB serial, and the device is in listening mode (blinking dark blue), you don’t need custom firmware. Connect to the device by USB serial and send it the w character. This will enter remote Wi-Fi set up mode and you can just wait for the prompt then send the next thing that’s requested. That’s how the Particle CLI sets Wi-Fi on the Argon using particle serial wifi.

I tried particle serial wifi but it failed a lot, so I used the doctor tool.

Make sure you’re not writing to USB serial using Serial.print or the SerialLogHandler when in listening mode from your firmware. It will interfere with listening mode commands such as particle serial wifi.

Still doesn’t work:

incoming serial data

	} else if(data == "clearCredentials") {
		remoteCommand(data);
	} else if(data.indexOf("setssid:") >= 0) {
		remoteCommand(data);
	} else if(data.indexOf("setpassword:") >= 0) {
		remoteCommand(data);
	} else if(data.indexOf("setauth:") >= 0) {
		remoteCommand(data);
	} else if(data.indexOf("setwifi:") >= 0) {
		remoteCommand(data);
	} else if(data.indexOf("restart") >= 0) {
		remoteCommand(data);

all data goes to this function. I tried doing it all in one command using Scanff but I get a blinky red light. So I broke each var out and did each command separately. Still doesn’t connect.

int remoteCommand(String data) {
if(data == “restart”) {
System.reset();
return 1;

} else if(data == "clearCredentials") {
        Particle.publish("log", "clearCredentials", PRIVATE);
	    WiFi.clearCredentials();
	return 1;

} else if(data.indexOf("setssid:") >= 0) {
	ssid = data.substring(data.indexOf(":")+1, data.length());
	
	return 1;
	
} else if(data.indexOf("setpassword:") >= 0) {
	password = data.substring(data.indexOf(":")+1, data.length());
	
	return 1;
	
} else if(data.indexOf("setauth:") >= 0) {
	auth = data.substring(data.indexOf(":")+1, data.length());
	
	return 1;
	
} else if(data.indexOf("setwifi:") >= 0) {
	
	if(auth == "WPA2") {
	    WiFi.setCredentials(ssid, password, WPA2);
	} else {
	    WiFi.setCredentials(ssid, password, UNSEC);
	}
	
	return 1;
	
} else {
	return -1;
}

}
