i am trying to send information to ubidots but i get a CIPMODE error. i am using the ESP-01 and arduino uno.

@xmex I think that you aren’t connecting it in the right form.
please follow the steps in this guide: http://ubidots.com/docs/devices/ESP8266-arduino.html
Best regards,
Metavix
done that thrice but still i get the same error
done that thrice but still its not working
@xmex Same erro? Could you post here a photo of your esp connected to Arduino, i need to check the leds on ESP
Best regards,
Metavix
@xmex sorry i made a mistake, the right connection is this:
Arduino —— ESP8266
D2 ——–> RXD
D3 ——–> TXD
3.3V ——–> VCC
3.3V ——–> CH_PD
GND ——–> GND
now i get an error CIPSEND.
now i get an error cipsend. initially i was stuck with cipmode error then edited the .cpp at AT+CIPMODE FROM “OK” to “ERROR”) !=NULL
NOW THE CIPSEND is a problem
@xmex i was trying to get the same error that you have, I found a possible explanation for that and it is the small timeout for CIPSEND, i gave just 1 second and it need wait more time to get a response. I will fix it and upload a new version.
Best regards,
Metavix
Metavix,
Have you corrected the cipsend error issue?. Can I know the changes?
