i’m new and I need your help. I have an arduino compartible NANO board with an integrated ESP8266. The controller it self is a ATmega328 with 32 KB of flash storage. I want to upload an ESP example sketch but the compiler tells me, that the ESP-library can’t be uploaded on a arduino nano. So I dont know how to set up the arduino. I hope you can help me.
Yes, thats it. Sorry for my bad english, i’m a german student.
It’s not really a Blynk related thing, but I think there is info here:
You should select the Arduino Nano board in the IDE and use the ESPSoftShield example for Blynk. Because it’s integrated as Shield, not as standalone ESP
I didn’t know that until now. I selected the Arduino Nano board in the IDE but where do I find the ESPShoftShield expamle? I didn’t find it in the example folder in the library.
Well, I would never thought that would actually come up with this thing, it looked a bit useless to me anyway.
You better get a separate ESP and Arduino. That way you see a lot better what you are doing. The ESP can be programmed stand-alone for Blynk too with the Arduino IDE. Since it has more memory than the Arduino, it’s a better solution anyway.
I use most of my ESP’s standalone and my “main” Arduino for the domotic stuff has an ethernet port so I can connect it reliably to the LAN, because my wifi sucks, lol.
I can see a header on the ESP part of your NanoESP board. You can probably solder some headers on there and try to communicate directly to the ESP with an USB-to-Serial convertor. You may be able to figure out which Firmware runs on the ESP part. I think there are some recommendations as to which firmware you need to run (0.22 I think, not sure, but that is on the forum).
If you access the ESP directly ou can give the AT commands and check the firmware with AT+GMR command.
I actually think that is the correct version. You may try setting the baudrate a little slower. I think that can be be done with AT+CIOBAUD=9600 but the command list is on the internet.
Then I don’t know whats wrong, but then again, I don’t know how they made that board in the first place. We’ll call in @vshymanskyy because he has more brains then us together, lol. He knows about the firmware versions.
