Hello ESP8266

Today i got first contacts between ESP8266 and Arduino Uno.

One Major drawback is, that the tx/rx is occupied by the ESP8266.

So once you can't really see whats going on and second you can't flash the Arduino when connected.

I added the EA DOG Shield to my Arduino to get some Response from the communication.

But viewed from now it is still some way to go.

I wonder if it is normal, that the ESP8266 gets hot.... i used the Schematic like from the ESP Breakoutboard.

BTW: Don't connect USB+ and Voltages > 5V together... PC did't like it (Rebootet) but i hope no further damage is happened.

tough one with an esp01 though, guys.

Are you sure? yes | no

I'd just use the standard serial on the ESP side buddy; I was more addressing the issue of not being able to flash the Arduino while the ESP is connected to the tx/rx pins :-)

? what do you mean?

I was under the impression that you've wanted to use a soft serial on the esp01 as well - nevermind - I wasn't paying attention enough.

Are you sure? yes | no

I second what @Radomir says. I'm currently using a software serial on my Arduino to communicate with my ESP8266 while keeping my main serial pins clear for flashing etc.

Thanks. I will try that.

You can always use a SoftwareSerial for the esp -- at least during testing.

Are you sure? yes | no

Thanks. Really good Idea. Later I can switch it over, because for the next step i need an additional Serial Port.

Are you sure? yes | no

Are your schematics still the same?

Are you sure? yes | no

Stefan-Xp wrote 11/22/2016 at 18:49

No I used the schematic of the

#ESP8266-01 Breakout

But i didn't use the switches. GP0 and GO1 are pulled to 3V3.

Are you sure? yes | no

ESP8266 and Arduino Uno still don't want to play

How it is not working
