No, this is my first time using this code.
We are managing to evolve, there were no more mistakes at the same point. Now I have an array error. I will post the Error.
//char mqtt_server[40];
//char mqtt_port[6] = "8080";

You need to sort-out your code formatting.

I was referring to post #22
Pete.
The WifiManager I have installed does not contain the following method:
wifiManager.setAPConfig(IPAddress(10,1,1,1), IPAddress(10,1,1,1), IPAddress(255,255,255,0));
Can you give me a WifiManager that contains this method?
otherwise your code will be deleted.
Pete.

I formatted the posted code. Is that what you’re talking about? Enclose in 3 quotation marks (```)?
They aren’t quotation marks, they are backticks.
The formatting is okay now.
Pete.
Can you help me with this? Should I remove the library and install the blynk wifimananger library?
What exactly is it that you are trying to achieve, and why?
Your comment about…
makes no sense to me.
Pete.
What I hope is to make a firmware that has the blynk token and that I can select the network and password if necessary. (no need to recompile the code again).
You’ll need to recompile the code if the token needs to be changed.
Why don’t you just use Blynk 2.0 WiFi provisioning?
Pete.
The token will not be changed. What I want is to change the ssid and password at runtime. The code I posted does this, but it’s giving an error in the wifimanager library.
How do you know that?
It’s sometimes necessary to refresh the auth token in Blynk 0.1, and it may be necessary in Blynk 2.0 also.
Pete.
It’s okay if I have to change the token. No problem, if you need I recompile. I have a machine that connects here at the company. When I bring it to the client I want to edit the network information without needing to recompile.
Which version of Blynk are you using, and what type of subscription plan do you have?
Pete.
I’m using version 2.27.29.
I don’t have a monthly plan, I buy resources when I need them.
So you’re using Blynk 0.1, which will be retired in around 6 months time.
Using Blynk for commercial purposes is illegal without a subscription plan…

Who will buy the blynk is the customer who will buy the machine. I’m just going to market the hardware.
