Esp8266+Arduino Bug or problem

Issues and Errors
1

Hello i try to use blink with esp8266 has a shield + arduino nano 328p

  • I change the firmware of my esp8266, i download from this tutorial:Connect to Blynk using ESP8266 as Arduino Uno wifi shield (Mac only)

  • I check the version using AT+GMR giving me this:
    酶酶鈧济济济济济济济济济济济济济济济济济济济济济济济济济济济济济济济该该窤T version:0.22.0.0(Mar 20 2015 10:04:26)
    SDK version:1.0.0
    compile time:Mar 20 2015 11:00:32

  • Then i change the baud use your command code from yours ESP8266_Shield_SoftSer:
    AT+UART_DEF=9600,8,1,0,0
    and giving me a: OK

  • i Upload ESP8266_Shield_SoftSer to my arduino nano and connect the esp8266 tx to rx (3), rx to tx(2) and works great when i opend the serial i see this:
    [19] Blynk v0.3.1
    [520] Connecting to FALI
    [3575] IP: +CIFSR:STAIP,"192.168.1.5"
    +CIFSR:STAMAC,"18:fe:34:a1:b4:39"

OK
[3602] Connected to WiFi

* In general, Soft Serial is unstable.
* It is highly recommended to switch to Hard Serial.

  • When i try to send to use blink in my smartphone i send a command to turn on a led on any pin, didn鈥檛 work, i see esp8266 recivided the command because blue led is blink when i send, but i think arduino didn鈥檛 execute the command.

  • i use arduino mega with hardser but didnt works do the same also i change the baud to 115200, i reset my modem too.

  • i probe with enc28j60 i works great but with esp8266 not.

  • i Used A nexus 5 with android 6.0.0, arduino 1.6.5, your last library 0.3.3, softwareserial. a regulator for eps8266 power and some resistor to the logic level of esp8266

hope help me with this, because i want to used this app for doing some fun project

Tayrondd,
SoftSer is only a test to confirm that the serial communications works between the ESP and the Arduino, which it is or you wouldn鈥檛 see the IP address etc.

Did you load a new sketch on the Arduino to test the Widget on your smartphone?

i didntt, i only upload the sketch below and use the botton widget in my phone for test only, but i didnt add to the sketch that i upload to arduino, so you say that the Esp8266 softser is only for test i didn`t work yet?, what happend with hardser?. thanks for your help!

Taryondd,

you have to give the Arduino something so it knows what to do with the button presses.
have a look at the examples, File|Examples|Blynk|more|Buttonpoll.
