I really do not know how to thank you, I would invite you to Italy for a lunch :D.
Thank you very much. Thank you for your availability and thanks again for helping us to finish this project for the exam.
Everything works great now.

Thanks also from the other guys who have done this project with me!

I am glad I could help you and the people reading this thread now and in the future. So the memory issues are gone? It was the String class causing problems?

So the memory issues are gone? It was the String class causing problems?
Exactly, now the dynamic memory has reached 63% and I have no problem. While with the string, over 50% started to give problems. The firmware update was not necessary :)

One last thing that does not hit anything with the programming:
I need to power the arduino with a 9V power supply (I think it will work, confirm?).

At the moment I use:
- arduino UNO wifi
- shield grove
- MQ-9 sensor grove
- MQ-131 (it is not grove but it is connected to the shield grove)
- Temp & Humi sensor grove DHT22
- Dust sensor grove
- Buzzer (it is not grove but connected to the pins of the Arduino through shield grove)

In your opinion, how many Ampere should be the power supply?

Thanks juraj ;)

Juraj

9 V is ok and at least 500 mA. biggest power consumer is WiFi transmission.

I would like to see a photo of the project, if it is possible. Grove is a very good concept.

Even 1 amp is fine, yes?

yes :) , what kind of picture? The schematic by fritzing or you mean a picture of only the Arduino with the sensors connected?

Juraj

1 A is very good.

1 A is very good.
oky, thanks you!!

I think you understand, do not you? :)

Hi, I had a similar problem, could you help me?
 
After updating the firmware (https://github.com/jandrassy/UnoWiFiDevEdSerial1)

I can not access the configuration at the address http://192.168.240.1/, and the LED is practically off.

If you offer me your help I would be really grateful.

Hello, thank you very much for your reply,
make sure you did not left EspProxy in FLASHING mode in Atmega and power cycle the board.
I have uploaded on the board, the sketch Esp Proxy after having commented the line // # define FLASHING // uncomment for use with esptool and FDT.
is this what you mean?

stefaniapep

no, the only error I find during the installation is at the command:
AT + CIUPDATE
that returns me error after CIUPDATE4

I opened a new thread, if you have any idea about what went wrong, a help is welcome :)
