.Using this on the NodeMCU 3 go well.
char auth[] = "xxxxxxxxxxxxx";
char ssid[] = "xxxxxxxxxxxxx";
char pass[] = "xxxxxxxxxxxx";
Serial.begin(9600);
delay(10);
// Set ESP8266 baud rate
EspSerial.begin(ESP8266_BAUD);
delay(10);
Blynk.begin(auth, wifi, ssid, pass );
How can I do on the Arduino Mega and ESP8266-01?
@mauroviana below is the ESP8288_Shield example in Arduinoâs IDE. Obviously you will change the board in the IDE to Mega from NodeMCU3. Also the project settings in the app will need to be Arduino Mega.

@mauroviana Hi guys.
im using local blynk local server but it is working fine. no any problem installed in Intel NUC I5 PC windows 10. before i run the java server, i configure first the ports manually from inbound firewall to make sure no problem from the firewall.
after that run the server to test wow, its working, then i created my local blynk account add some project. and it works very well.
other than that i create batch file and convert it to â.exeâ then i put to run folder so every time s restarted my local server my blynk server java apps is automatically run by it self. so coolâŠ

I think that I just needed of this:
Blynk.begin(auth, wifi, ssid, pass, "192.168.xx.xx" );
I need help with this:
How to read the historic?
I need of some program to uncompress this data?
What is the best way of enjoy of it?
Sorry for so many questions.
Good to see you have some data now @mauroviana
csv fileâs can be opened in Excel to produce your own fancy graphs.
.gz are just compressed zip files (Use 7zip).
I donât think the bin files are for you and I to touch, right @Dmitriy?

Correct. BINs - are binaries. For human data we have CSV API and button in history graph.
Iâm having dificulties to work with the WiFiManager and Blynk. Can you tell what I need? Iâm trying this code, I can save the configurations in the WiFiManager but the Blynk doesnât begin.

What is this supposed to do?
Are you trying to connect to Blynkâs server or another server?
If it is another server you will need:
Blynk.config(blynk_token, "xxx.xxx.xxx.xxx"); // enter IP address
When I use WiFi Manager all I use is Blynk.config() because it is already connected to the WiFi router so your line of:
Blynk.config(WiFi.SSID().c_str(), WiFi.psk().c_str());
makes no sense to me.
The other thing to do is ensure you display variables in Serial Monitor to be sure they are exactly how you expect them to be.
At my server, the âBlynk Serverâ.
Iâve have tried this to connect.
This is what appears at the Serial Monitor:
Conectando...
[580923] Connecting to blynk-cloud.com:8442
[581937] Invalid auth token
If you want to connect to YOUR server that is running the Blynk server software then you need to include an IP somewhere. Connecting to blynk-cloud.com:8442 states you are trying to connect to Blynkâs cloud server not one of your servers.
Do you mean storing tokens etc on an Arduino instead of on an ESP i.e. a WiFiManager equivalent for Arduino devices?
yes arduino and esp8266 together.
This is a subject I have looked at very closely.
When I first became a Blynker I knocked up some very bad code that used an Android app called DroidTerm to do this.
There are several threads on this site about implementing it with EEPROM for Arduinoâs.
There are several Apps that can do the same as WiFiManager but they are ESP based.
Very recently I found the âperfectâ solution but itâs not something I can say much about.
Yes, Iâve seen some of they but I havenât found none of then that can help me to understand and adapt to my necessities.
Yes but I think that the âATmega328Pâ and âESP8266â together Iâll have more options of ports.
I understand. Youâve helped me so much and I can just thanks you. Iâm still searching for this âperfectâ solution, if everything goes well I want that the client can himself put your login, password and token before begin the Blynk.
