problem connecting wifi of robotdyn

Using Arduino Installation & Troubleshooting
#1

i am not able to load the page using 192.168.240.1.
neither m able to get the ssid as arduino uno fifi instead m getting ssid as ESP_9EE0D7 to this ssid i am able to connect but still not able to load the page 192.168.240.1

and i also have problem with the firmware updataion using windows with esp recovery tool. after uploading the esp tool and when i am testing the connection it gives error .

Can't communicate with programmer! at cc.arduino.plugins.unowifi.flashers.cli.CLIFlasher.testConnection(CLIFlasher.java:100) at cc.arduino.plugins.unowifi.UpdaterImpl$2.run(UpdaterImpl.java:112)

please need an urgent solution

#2

did you load the EspRecovery sketch into the Atmega of Uno WiFi to bridge the connection to the esp8266? and did you put the esp8266 into bootloader mode with B/L button?
And do not touch the bottom of the board while you hold it. Use the plastic cover to protect the bottom side.

#3

thank you for the rply
the thing is that the board which i am using is the uno wifi robotodyn

#4

change the title if it is the Robotdyn board

switch the switches 5 and 6 ON for esp8266 to USB and switch 7 for uploading to esp8266 and then reset the esp8266 to enter the bootloader mode

#5

plz send me the steps on how to switch the switches and all.

i am using UNO+WiFi R3 ATmega328P+ESP8266, 32Mb flash, USB-TTL CH340G, Micro-USB board

i have also attached the photo of my board.

scroll down this page

#7

after flashing the esp8266 you can connect Atmega to esp8266 over serial (switches 1 and 2), but it is not practical because you then can’t connect Serial Monitor. better is connecting Atmega to USB (3,4) and connect RX/TX of esp8266 on board header with jumper cables to a pair of Atmega pins used with Software Serial like it is common with standalone esp8266 modules. use level shifters to protect esp8266 form 5 V of Atmega pins

#8

i tried the following code from the robotdyn site

void setup()

{ Serial.begin(115200);

pinMode(13,OUTPUT);

delay(500);

Serial.println("AT+CIPMUX=1");

delay(2000);

Serial.println("AT+CIPSERVER=1,5000");

delay(2000);

Serial.println("AT+CIPSTO=3600");

delay(2000); }

void loop()

{ while(Serial.available())

{ char Rdata;

Rdata=Serial.read();

if(Rdata=='A'|Rdata=='a')

{ digitalWrite(13,HIGH);

delay(50); }

else if(Rdata=='B'|Rdata=='b')

{ digitalWrite(13,LOW);

delay(10);

digitalWrite(13,HIGH);

delay(10);

digitalWrite(13,LOW); }

else

{ digitalWrite(13,LOW); } } }

but its giving me error

espcomm_sync failed
error: espcomm_open failed

#9

you have only switches 5,6,7 ON and you did reset the board before uploading?

(and this sketch is for Atmega)

#10

i tried to reset the board but somehow it was giving me an error

if i tried to update the firmware it was giving error.
i tried using esp tool to update the firmware.

#11

and upload to Atmega is working?

#12

upload to atmega meaning are u asking about whether m able to upload the sketch ??

if yes then ya i am able to upload the sketch and control my display.

i have only issue with the wifi connectivity. which i need to control the display through app.

first of all i am able to see the ssid as ESP_9EE0D7 of my robotdyn board in the network scan of my computer.

#13

you see the access point because it is enabled and the setting is persistent in the WiFi part of the esp8266. it will be there even if you would upload Blink.

and AT firmware is in the esp8266 or you managed to upload something earlier?

#14

no i didn't upload anything.

#15

then AT firmware is there. set switches 5,6 ON all others off, connect with Serial Monitor, set baud rate 115200 and CR/LF and send AT. it should respond with OK.

#16

set switches 5,6 ON all others off,

should i connect pin 5 and 6 to vcc of the arduino board??

#17

gourish:
should i connect pin 5 and 6 to vcc of the arduino board??

No. I write all the time about switches:

#18

then AT firmware is there. set switches 5,6 ON all others off, connect with Serial Monitor, set baud rate 115200 and CR/LF and send AT. it should respond with OK.

it gives me this error.

#19

Serial Monitor can’t give you that error

#20

Serial Monitor can't give you that error

the error is displayed in arduino IDE

what i am doing wrong??
