Why WiFi-Manager directs to 192.168.244.1 instead of 192.168.4.1? (SOLVED)


#1

Hi,

Does anyone know why this happens? Takes me to a site where i should type “IP unset”-fields. I´m using NodeMCU 1.0.

Is there some way to fix this problem?

Thanks.

Pete.

Thanks, but thereś still something I don´t get now. I tried with these 2, but the first one changed to address I need to use to get to the config and second one filled those “IP unset”-fields. Still it takes me to that 192.168.244.1. And login doesn´t work. Hereś the code I try to use also. What I´m doing wrong here?

So these i tested to add:

wifiManager.setAPStaticIPConfig(IPAddress(10,0,1,1), IPAddress(10,0,1,1), IPAddress(255,255,255,0));

wifiManager.setSTAStaticIPConfig(IPAddress(192,168,0,99), IPAddress(192,168,0,1), IPAddress(255,255,255,0));

/*
This example will open a configuration portal for 60 seconds when first powered up. ConfigOnSwitch is a a bettter example for most situations but this has the advantage 
that no pins or buttons are required on the ESP8266 device at the cost of delaying 
the user sketch for the period that the configuration portal is open.
 
Also in this example a password is required to connect to the configuration portal 
network. This is inconvenient but means that only those who know the password or those 
already connected to the target WiFi network can access the configuration portal and 
the WiFi network credentials will be sent from the browser over an encrypted connection and
can not be read by observers.

I clicked on Pete’s link above, it turned out to be a pretty good resource, and i was able to find that others were having the same issue, two years ago.

The problem, as i read it , was for no reason, no one could tell why it seemed to pick on them.

Someone said the fix was to reflash your device.
But i see what you’re doing is just trying to re-write your code. Im not sure why. Can you tell us why you’ve decided not to use the fix on the github, and just go for writing different code? It says right on there that they were fixed after reflashing. Can you explain a little more?


#5

I have tried many different codes and everytime the same happens. I also have tried to ran this “EraseEsp8266Flash-master” via Arduino IDE, but it hasn´t worked for me. It gives an error and resets for some reason. I also ran NodeMCU flasher with a blank flash.

Just a minute ago I tested “Template_ESP8266.ino” from github (Blynk-library/examples/Blynk-inject/Template_ESP8266) and it took me first time to 192.168.4.1 and asked WiFi SSID, Password, Auth token, Host and Port.

I use Blynk server, so I guess the “host” should be “Blynk.cloud-com” And port “80” or “8080”?

And it still doesn´t connect. What is going on here? Or what fix you meant Ivennard?

I also have 2 NodeMCU´s in this “machine” of mine. Is it possible to set the SSID and password for 2 NodemMCU´s at one time?


#6

I think you need to decide if you’re trying to get WifiManager or Blynk inject working, as asking questions about both in the same thread is difficult.

I notice from the code that you’ve no supplied that you’re not using the main tzapu branch of WiFiManager but a Ken Taylor branch. I like the stuff that Ken Taylor does, but there have been no code updates for two and a half years, so I’d say that branch is now dead.
The tzapu master branch also hasn’t had any updates for two and a half years, but this branch is being actively developed:

I’ve never used Blynk Inject, but if its asking for a server IP address then you probably need to ping blynk-cloud.com from your PC to get the correct IP address for your local server.

No, the config is stored in the memory of the individual NodeMCU.

One other comment - I see lots of people struggling to get WifiManager or similar provisioning software to work when the majority of time it’s not actually needed.
I only use WifiManager for projects that other people are going to use in their own homes. The rest of the time I hard-code all the credentials I need into the sketch for that device. If I want to change these then I use OTA to allow me to change the sketch without the need for physical access to the NodeMCU.

Pete.


#7

I really don´t know now what is going on. I pinged the Blynk-cloud:

“Pinging blynk-cloud.com(192.168.244.1) with 32 bytes of data”

Why it gives that “244”?

And tried all variations for server to log in, but no luck. I also use that “tzapu/WiFiManager”.

I´m totally lost now. But I continue struggling with this, cause I´m trying to do couple of these for my friends. Otherwise I could just hardcode it i know that.

But thanks anyway for trying to help.


#8

Assuming that you’ve not mis-typed this IP address, you have something VERY strange happening with your network setup.
Can you please post the actual output from your command prompt window when you do this ping?

Pete.

Yes I think so too. Something VERY strange. But hereś what it says:

#10

This is the IP address of the Blynk cloud server in Frankfurt, so that’s the correct result.

With your other computer, and possibly your NodeMCU, it’s seeing what I assume to be an internal IP address. What IP address range are you using for your home network?
You mentioned that the computer that gives the correct IP address is connected via a cable. Is the other connected via Wi-Fi? if so, what happens of you connect that via cable and disable Wi-Fi?

Do you have any weird and wonderful network setup - private DNS server, local routing table entries on the “strange” PC, multiple DHCP servers etc?

Pete.


#11

I just noticed that I´ve made a mistake. I have somehow mixed those different WiFi-Manager-libraries. Now when I use the “WiFiManager-development”-library, I managed to connect with my phone and WiFi-manager. It still directed to 192.168.244.1 and asked many things there in the config, but I filled only those SSID and password-fields. And it connected.

So seems like it was because of wrong WiFi-manager-library. Done only one test now, but looks promising.

Thanks for your help. I do more tests and see if it really works.


#12

No. Seems like my phone just made it look like it connected, but I think it only disconnected from NodeMCU`s and picked up the old WiFi from the list automatically. So… Now this ask a lot more in the WiFi-config. SSid, password, Static IP, Static Gateway, Subnet and Static DNS. And it still directs to 192.168.244.1. So when it works it should ask only SSID and Password… right?

This is really weird.


#13

I’m sorry, I don’t really understand the question.

Usually, when people are using WifiManager with Blynk they add fields to the static portal to allow SSID, WiFi Password and Blynk Auth Code to be inputted.

They then use Blynk.begin(auth, ssid, pass); to use a DHCP allocated IP address for the device and connect to Blynk cloud.

If you need to be able to specify a static IP address for your device, as opposed to one allocated by your DHCP server (router) then you’ll need to change your code to manage your own Wi-Fi setup using something like
WiFi.config(device_ip, dns, gateway, subnet);
followed by
Blynk.config(auth, blynk_server, blynk_port);
Blynk.connect();
commands.

Maybe if you explained a little more about what exactly you’re trying to achieve, why you need to use a library like WiFiManager rather than hard-coding credentials, and sort of scenarios where your devices are likely to be used, we’d be able to give you more targeted advice.

Pete.


#14

Well… This is a automatic hydroponic system, which checks the water level using ultrasound sensor and uses valves and pumps during watering process. Here´s part of the code, whole code is too long here… To this I´d like to include WiFi-Manager cause I´d like to make couple more of these… For my friends without profiting. But still it´s too hard to use hardcoded method here. Maybe I try with other computer… this is so strange anyway.

Okay, so you’ve shared a load of code that has no WifiManager items in it, and the only item of interest is the shightly strange way in which you’re doing you’re Blynk.begin…

Blynk.begin(auth, ssid, pass, IPAddress(139, 59, 206, 133), 80);

if you did

Blynk.begin(auth, ssid, pass);

Then it would achieve exactly the same result.

As I said before, the Auth code, SSID and Wi-Fi password are the only three fields that you need to capture when using WifiManager with Blynk Cloud, provided you don’t need your devices to have a static IP address (which you’re not doing at the moment in this code).

If you want examples of how to capture these three items via the WifiManager static portal and save them to EEPROM then you’d be better searching this forum than github.

Pete.


#16

Yeah I´ve tried to test that WiFi-manager by itself before including it to this long code. To find the best way to do it first. So there is no WiFi-manager stuff in this code yet, but you asked about this project so I told you about it.

I try to search the Blynk-forum and keep on struggling. That´s ok I´m used to it.

Thanks.

#18

If you get compile errors with that code then you need to downgrade your ArduinoJson library from 6.x.x to 5.13.5

Pete.

Browser gets stuck at http://192.168.244.1/wifisave
and says:
"

Trying to connect ESP to network.
If it fails reconnect to AP to try again
"
And my laptop (which I used to set the config) is not connected to any network anymore.

What this means? Is NodeMCU connected or not? This is a bit confusing.

Update:

I tried this with 2 more NodeMCU´s and I get the same result. Second time I connect power to NodeMCU the serial monitor gives this:

*WM: [2] Connection result: WL_CONNECTED
*WM: [3] lastconxresult: WL_CONNECTED
*WM: [1] AutoConnect: SUCCESS 
*WM: [1] STA IP Address: 192.168.10.54
connected...yeey :)
BLYNK Connected
*WM: [3] freeing allocated params! 
*WM: [3] unloading 

So seems like it connects to Blynk automatically. So how this works? How can I set new SSID and password for it when I want to use other network? How to reset it?

Sorry I´m totally novice with this WiFi-manager.

Thanks

Can you post your full WifiManager code?
