ROBOTDYN card. Mega + WiFi R3 ATmega2560 + ESP8266 (8 Mb mémoire)

Hello

I have the same board

I am tryng to comunicat with it

I am using blynk app

I set the pins to (usp<> esp) mode

Then i upload  esp stand alone example by using arduino ide blynk library.

The esp shown as online on my app

But i coudn't connect the arduino to my device app (blynk)

I already asked the blynk community and they direct me to your site.

Do you know what to do ?

Best regards,

Hi,

I did some try too with Blynk, but i didn't used the "stand alone example". For me it can't be considered as "Alone"  ....except if u want us the ESP itself only

I think it will be better t to consider the ESP as Arduino shield, connected.

Honnestly, i didn't succed even on this way ... refered to "Userbin" chat upper, we have all, problems to make both connecting.

If u find urself some solutions, i will be glad to read about it.

Best Regards

I found this comment too on the china web site i bought it :

"The description states very precisely how to use the dip switches on this board for the different modes. The most important mode and the only reason why I bought this board is to use the Mega together with the ESP to be able to connect the Mega with the WWW. This mode DOES NOT work. It is possible to use the Mega and the ESP separately but NOT together. This makes the price for this board extremely high because the single components are cheaper. Due to the testing I had to perform I missed the dead line to open a dispute."

I try the sketch by BISSA ORBOEA and its working... thanks for your knowledge sharing... BISSA

I have the very same device and the very same problem. I read all the information I could find on this device and I tried all the code but I only can us it as a normal Arduino Mega. I have no clue on how to get the ESP8266 working.

Did somebody made some progress on this in the meantime or do u just use it as a  really overpriced Arduino Mega?

Whren I try the code mentioned above I get following error:

<command-line>:0:9: error: expected identifier before numeric constant

C:\Users\...\Documents\Arduino\libraries\arduino-ESP8266-master/ESP8266.h:69:7: note: in expansion of macro 'ESP8266'

exit status 1

I have my board set to "Generic ESP8266 Module" as mentioned here: MEGA+WiFi R3 ATmega2560+ESP8266, flash 32MB, USB-TTL CH340G, Micro-USB

but also set to Arduino Mega I get a different Error Message:

MEGA_WiFi:6: error: no matching function for call to 'ESP8266::ESP8266(HardwareSerial&, long int)'

MEGA_WiFi:18: error: no matching function for call to 'ESP8266::getVersion()'

MEGA_WiFi:20: error: 'class ESP8266' has no member named 'setOprToStation'

MEGA_WiFi:30: error: 'class ESP8266' has no member named 'getLocalIP'

no matching function for call to 'ESP8266::ESP8266(HardwareSerial&, long int)'

Does somebody now how to fix this? I am getting really frustrated at not progressing at my project

Hola compañeros, yo tambien estoy peleando con la placa robotdyn 2560+wifi .

Por si os sirve de algo tengo un .pdf que consegui que me enviara un chino despues de ser muy pesado pidiendole informacion .

Haber si entre todos hacemos funcionar la bicha.

Hello, I am a new coming here, and also a new starter in this board ,now i still have the problem even i follow the link you post.

I want to ask that before you upload the sketch what is the board you select? ()

Thank for your information. Arduino/Genuino Mega/Mega2560  or Generic ESP8266 Module)?

For upload the sketch to the board:

5, 6, 7 ON

RXD3 - TXD3

For run the sketch:

5 and 6 ON

RXD3 - TXD3

It works

Thank you very much for helping. About this problem, which board did you

selected? "Generic ESP8266 Modules" or Atmega2560?

Best regards,

You are wellcome.

I have ATmega2560+ESP8266, flash 32MB, USB-TTL CH340G, Micro USB.

You have to select: Generic ESP8266 Module
