I still have connection problems:
"Failed to disable echo"
but I can not understand why ...
firmware esp2866 is:
AT + GMR
AT version: 0.40.0.0 (8 Aug 2015 14:45:58)
SDK Version: 1.3.0
To-Thinker Technology Co., Ltd.
Build: 18.104.22.168 Sep 11, 2015 11:48:04
so I think this is not the problem as the required firmware is the sdk 1.00 v0.22;
I also powered externally esp2866 to avoid power problems;
pins esp2866 TX and RX are respectively connected to pin 3 and pin 2 of the Arduino;
the code used is:
define BLYNK_PRINT Serial // Comment this out to disable prints and save space
// Set ESP8266 Serial object
SoftwareSerial EspSerial(2, 3); // RX, TX
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth = "YourAuthToken";
// Set console baud rate
// Set ESP8266 baud rate
// 9600 is recommended for Software Serial
Blynk.begin(auth, wifi, "ssid", "pass");
I would be glad if someone could help me ... I do not know what to do ...
